A Tour of the HOBOware Interface
This is the main HOBOware window. Use the menu bar or tool bar to access all the features within HOBOware. The status bar at the bottom of the window shows the current view in place (as selected by the Window menu) as well as the device currently selected or connected, if any.
This example shows a file that has been opened and plotted. There are three components to a plotted datafile: the Points Table, the Details Pane, and the Plot.
The Points Table
The Points Table is a list of data points, or values, and logged events displayed in the plot. The Points Table is linked to the graph: only the data for the series and events on the plot are listed in the Points Table.
The data points are listed chronologically. Each point or event is listed in a single row and each series or event type is displayed in a column. You can resize the columns by clicking and dragging the dividers between the column headers.
Use the arrow keys or scroll bars to move up, down, left, and right in the Points Table. Additionally, as you click the crosshair tool event cell in the Points Table, the crosshair will appear on the graph at the time corresponding to that cell.
in the plot, the corresponding point is selected in the Points Table. Similarly, if you click a value or
To resize the pane, drag the divider between the Points Table and the plot. To hide the Points Table, select Points Table from the View menu.
1-800-LOGGERS 10 www.onsetcomp.com
Page 11
HOBOware User’s Guide
If you do not want the Points table to be displayed by default when you plot data, open the Preferences, select Plotting, and then Layout. Disable the "Show the points table when plotting data" checkbox.
The Details Pane
The Details Pane shows information for each series and event displayed in the plot including:
Information about the devices, such as model and serial numbers.
Deployment information, such as the launch description, deployment number, start time and time
zone, logging interval, and battery voltage at launch.
Series statistics, such as the total number of sensor samples and events, time of the first and last
sample, and the maximum, minimum, average, and standard deviation for each sensor series in the plot.
Audit trail information for secure files.
Click the + or - button to expand or collapse an entry in the Details Pane. Click the Expand All/Collapse All buttons to expand or collapse the entire details tree.
Click a series node in the details tree to select the corresponding series on the graph and corresponding column in the Points Table.
Right-click a series to hide it on the plot and in the Points table. The hidden series will be grayed out in the Details Pane. Right-click a grayed out series to show that series or select Show All Hidden Series to show all series that were previously hidden.
To resize the pane, drag the divider between the Details pane and the graph. To hide the Details Pane, select Details Pane from the View menu.
If you do not want the Points table to be displayed by default when you plot data, open the Preferences, select Plotting, and then Layout. Disable the "Show the details table when plotting data" checkbox.
The Plot
The plot displays the data series and events in a graph. The plot has a time axis (x-axis) and a value axis (y-axis) for each series selected in the Plot Setup window. The title, displayed at the top of the plot by default, is the Description in the Plot Setup window. The legend, displayed to the right of the plot by default, lists the keys for each series (line colors and marker types). If the crosshair tool is in use, it also lists the date, time and point values
currently selected by the crosshair. For secure files (.hsec and .dsec), a padlock icon to the names of the series that were verified as original data.
appears in the legend next

HOBOware User’s Guide
To show or hide the title or legend, use the View menu. Double-click a plot element (series, axis, title, or legend) to change its properties or right-click the plot and select the item from the menu.
For more details on working with plot, see Reading Out, Plotting, and Analyzing Data.
Working in Secure Mode: 21 CFR Part 11 Compliance
You can create secure files in HOBOware Pro to comply with 21 CFR Part 11, or simply to add a level of security when working with datafiles. When Secure Mode is enabled, HOBOware Pro begins an audit trail in the logger when you launch it and adds an encoded digital signature to the new datafile when you read it out. A digitally signed file, or "secure file," has a filename extension of .hsec (for most U-Series loggers) or .dsec (for station-type loggers).
Notes:
Issues may arise if you do not always use HOBOware Pro in the Secure Mode, if you sometimes use
HOBOware, or if you sometimes use a version of HOBOware prior to 2.3.0. The resulting file issues are described later in this section.
This feature is not available for use with HOBOnode Manager and its associated ZW series data node
files.
Project (.hproj) and export files are not secure, even if you create them from secure files.
To enable secure mode:
1. From the File menu in Windows or the HOBOware menu in Mac, select Preferences
2. Select General and then select Data Verification.
3. Select the Enable Secure Mode checkbox.
4. Click OK. When Secure mode is enabled, a padlock icon main HOBOware Pro window

HOBOware User’s Guide
Opening a Secure File and Data Verification
Secure files can be opened with HOBOware Pro 2.3.0 or greater. You can open .hsec files only with HOBOware
2.3.0 or greater.
Every time you open a secure file – even when you are not in Secure mode – HOBOware verifies the encoded digital signature to detect whether the file has been corrupted or tampered with. When a file is verified as secure,
the padlock icon
Filtered series set up prior to launching or created after readout are not verified.
Series that were created as a result of user input after readout, such as running a data assistant or
Series retain their verification status (and padlock icon) when copied and pasted into other plots.
In the Details pane, audit trail information is displayed under the Data Verification node for each series. HOBOware Pro automatically obtains the Launch User and Readout User names from your computer's operating system. To save the Launch User name, you must have Secure Mode enabled when you launch the logger.
If the digital signature cannot be verified when you open a file and even a single bit of data has changed since readout, a warning message will appear that verification has failed. This means that the file has been altered or become corrupted since it was originally saved. You may still be able to plot the data from the file, but the padlock icon will not display in the legend or there will be no signing information in the Details pane. You will still be able to perform typical HOBOware functions on the file.

File Compatibility
Depending on the type of logger, the version of HOBOware that launched the logger, and the version of HOBOware that reads out the logger, the resulting datafile may not be compatible with versions of HOBOware prior to 2.3.0 or you may not be able to read out the logger at all. The following files are created when launching and reading out in these scenarios:
Launching and reading out in non-secure mode with any version of HOBOware. A backward-
compatible datafile (.hobo or .dtf) is created.
Launching in non-secure mode with any version of HOBOware and reading out in secure mode.
A secure file (.hsec or .dsec) is created with an audit trail that lists the readout user, but not
the launch user. Secure files are not backward-compatible.
Launching in secure mode and reading out in a pre-2.3 version of HOBOware. Most U-Series
loggers cannot be read out. A backward-compatible datafile (.dtf) is created for station loggers.
Launching in secure mode and reading out in non-secure HOBOware 2.3. A datafile (.hobo) is
created for U-Series loggers, but it is not backward-compatible. A backward-compatible datafile (.dtf) is created for station loggers.

Chapter 2 Working with HOBO Data Loggers
Working with HOBO data loggers involves the following basic steps:
1. Connect the logger to the computer for the initial setup and launch.
2. Launch the logger. Enter or select the appropriate parameters for the logger deployment and then launch, or start, the logger.
3. Check the status of the logger. You have the option of checking the current status of the logger and any current readings while it is still connected to the computer. This can be helpful to verify that the launch configuration is as expected.
4. Read out the logger. After deploying the logger, read out all recorded data and save it to a file. Many devices also work with shuttles that allow you to keep the logger in the field, but still read out any recorded data. You can then bring the shuttle back to the office, connect it to the computer, offload and save the files.
HOBOware User’s Guide
5. Plot the data. After reading out the logger and saving the data, you can select and define the data series you wish to plot in a graph. Data Assistants may be available for automatic scaling of certain data when plotting.
6. Analyze the data and customize the plot. There are numerous tools available for working with the data and changing the plot, such as exporting, filtering, merging files, cropping, and more.
7. Save changes to the plot as a project file. Changes to the axis, series, plot, and legend properties as well as any filtering or merging can be saved as an .hproj file.
Connecting Devices
Most HOBO data loggers and shuttles connect to the computer with a USB cable. The HOBO Weather Station, HOBO Micro Station, and HOBO Energy Logger connect to the computer with a serial cable (or to a USB port with a Keyspan™ serial adapter).
Some loggers require an optic USB base station/coupler to connect to the computer. Consult the manual that came with your device for specific information about required base stations/couplers or cables.
Once a device is properly connected to the computer as described below, the device name is listed in the status bar at the bottom of the main HOBOware window.

Launch Logger Window
Use the Launch Logger window to set up your logger to record data. The Launch Logger window is divided into the following three panes:
Logger Information. The model of the logger currently selected appears at the top of this pane,
which also includes the serial number, deployment number, and current battery level.
Use the Name field to type up to a 40-character name for the logger deployment. The name you enter here will be used as the default file name when you read out the logger and save the data. It will also be the default title on the plot. For new loggers, the name defaults to the logger serial number.
Click the Status button in this pane to see the current status of the logger and the settings used on the previous launch.
A User Notes button may also appear for some loggers. Click it to enter more extensive notes about the deployment.
Sensors. This pane displays a list of the sensors available for the logger. Choose the sensors, or
channels, that you wish to log in this deployment, select any external sensors you may be using, and type labels for sensors as desired. Note that labels may not be applied to some calculated or derived channels, such as filtered series. This pane also displays any utilities available for your logger, such as Alarms, Scaling, and Filters. For the HOBO Plug Load logger (UX120-018) logger, you also have the option of configuring statistics for each channel in this pane.
Deployment. Use this pane to select the logging interval (the rate at which you want the logger to
record data) and to choose when the logger should begin recording data. Loggers can be configured to start logging immediately or on a specific date/time. Some loggers also can be configured to start at an interval or start with push button/coupler start. The coupler start (also known as a triggered start) involves removing the logger from its coupler or base station and then taking it to the deployment location. When you are ready for logging to begin, insert the logger in the coupler without the base station for three seconds. Refer to the logger manual for details.
This pane also displays the logging duration, which is the approximate time it will take to fill the logger memory based on the logging interval, sensors, and other settings currently selected. For some loggers, you can also set a sampling interval, choose when to stop logging, and select other options in this pane.
When you are done choosing the launch settings, click the button in the lower right-hand corner of the window to send the settings to the logger. Note that the button text changes based on when you chose to start logging.
HOBOware Pro Tip: If you will be using the same launch settings for multiple deployments of the same logger type, select the Skip Launch Window Next Time checkbox to bypass this window the next time you launch a device. This will cause the next logger to be launched with either the previous launch settings or the current logger settings as set in Launch Time-Saving Options subcategory of the General preferences.
The options available in the Logger Launch window vary depending on the type of logger you are using. For more details about launching your particular device, refer to the following topics:

launched. Each time you start a new launch, the deployment number increases by one.
Battery Level. This shows the current battery level in the logger.
Status. Click the Status button to check the logger settings from the previous launch.
Sensors
The Sensors List displays all internal and external sensors available for recording data. Choose the sensors, or channels, that you wish to log in this deployment. To configure a sensor:
1. Select the sensor(s) you wish to log.
2. Choose the measurement to log (e.g. State, Runtime, etc.) from the drop-down list.
3. Type a label for the sensor, if desired.
4. Complete additional details for the sensor. This will vary depending on what the logger will be measuring. For most sensors, type a name and select a description pair from the drop-down list. For external Pulse channels, click the button for the corresponding channel in the sensor list to select the sensor type as shown below. If you select Raw Pulse for the sensor type, you can use Data Assistants to set up kWh (HOBOware Pro only) and pulse scaling information as necessary, which will also display
1-800-LOGGERS 18 www.onsetcomp.com

HOBOware User’s Guide
on the logger LCD screen. Note that sensors that support Data Assistants at launch time display the kWh and/or scaling icon next to their name.
5. Repeat steps 1 through 4 if your logger supports multiple sensors.
6. Set the units that display on the logger's LCD screen. When the sensor is configured to log State or Runtime, choose either:
"Time" to show the total amount of time the switch has been closed or on since logging began,
ranging from seconds to days; or
"%" to show the percentage of time the switch has been closed or on since logging began.
When the sensor is configured to log Pulse or Event, the LCD will display the units in three characters. Accept either the default units or type your own three-character units.
Notes on configuring sensors:
Click the Filters button to create additional filtered series for any of the channels you configured. The
filtered series will then be automatically calculated when you read out the logger and plot the data.
Click the Advanced button to access the following settings specific to the logger: Pulse Frequency and
Lockout Time, Occupancy, and Calibration.
When setting up a pulse sensor, consider setting up the launch for a delayed or push button start and
then connect the sensors/devices later before logging begins. after logging begins may not log accurate data.
Important: Sensors that are connected
The Occupancy/Light logger (UX90-005x/-006x) also automatically generates additional series upon
reading out the logger to give you combined statistics, such as how long the lights were left on while the room was unoccupied. These series will be available in the Plot Setup dialog when opening the datafile.
You have the option to record the logger's battery voltage at each sample time; this is the last channel
in the sensors list. Like the other data channels, logging the internal battery channel consumes some of the logger's memory. Unless you suspect abnormal battery performance, you do not need to log the battery voltage. You can also hide the battery channel with Series preferences (in Preferences, select Display, then Series).
Note that labels do not apply to calculated or derived channels, such as filtered series.

Logging Duration. This lists the approximate time it will take to fill the logger memory based on the
logging interval and sensors currently selected. This is a theoretical estimate only; battery life and frequent state and event logging will affect your deployment. This estimate is only available when the sensors are configured to log Pulse or Runtime. For estimates with State and Event logging, refer to the logger documentation, also available at http://www.onsetcomp.com/support/manuals.
Start Logging. Select when to launch the logger. This defaults to the setting for the logger's previous
launch (you can change this in HOBOware Pro with the Launch Time-Saving Options subcategory of the General preferences). You can choose to launch this logger:
Now. Logging begins as soon as you click the Start button in the Launch Logger window.
At Interval. Logging will begin at an exact interval (for example 9:00:00 rather than 8:47:00 when
you choose a one-hour logging interval). The exact start time depends on the logging interval you choose. This option is only available when the sensors are configured to log Pulse or Runtime.
Push Button. Logging will not start until you press the Start/Stop button on the logger and hold it
down for at least three seconds. The LCD screen on the logger will display "Start" until you press the button.
On Date/Time. Logging will begin at a date and time you specify, up to approximately six months
from the present. The LCD screen will count down to that start date/time and then logging will begin.
Stop logging. Select when you want the logger to stop logging. You can choose:
When memory fills or Never (wrap when full). If you select "When memory fills," then the logger
will stop recording data once the memory is full. If you select "Never (wrap when full)," the logger will record data continuously until either the logger battery runs out or you stop it. Once the logger is full, the newest data will overwrite the oldest data. When wrapping, the memory segment on the logger LCD screen will blink.
Push button. When this option is selected, the logger will stop recording data when you press the
Start/Stop button on the logger itself for 3 seconds. The LCD screen on the logger will display "Stop" when this option has been selected.

Allow button restart. This setting is available when "Push button" is selected as a "Stop Logging"
option. If you select this option, you can resume logging on the next even logging interval on a stopped logger by pressing the Start/Stop button for three seconds. For example, press the Start/Stop logging button on the logger once to stop logging. Then, a few minutes, hours, or even days later when you are ready to continue logging, press the Start/Stop button on the logger again and logging will resume at the next even logging interval (i.e. if the logging interval is set at 1 hour and you press the button at 10:15 AM, logging will not resume until 11:00 AM, which is the next even interval based on the 1-hour logging interval). You can then continue to start and stop logging as often as you'd like during this same deployment. Any gaps between when you stopped and restarted logging during this deployment will be reflected on the plotted data when you read out the logger. Once you relaunch the logger, a new deployment and datafile will begin. The data from the previous deployment will not be carried over to the new one.
Specific stop date. Select the date you want the logger to stop recording data. Choose either a
preset time or set your own custom date and time. Note: If you select a specific stop date and also have the logger configured to resume logging on the next button push, then the logger will stop logging at the date you select regardless of how many times you stop and restart the logger with the Start/Stop button.
Options. Select "Turn LCD off" if you want the logger to operate in "stealth mode" with the LCD
screen turned off. You can override this temporarily by pressing the Start/Stop button on the logger. The LCD will then remain illuminated for 10 minutes.

With Burst Logging mode, you can configure the logger to use a different logging interval when specific conditions are met. With Statistics mode, you can configure the logger to calculate maximum, minimum, average, and standard deviation for all enabled sensors (except battery voltage) during logging at a sampling interval you specify. Keep in mind that the more statistics you record, the shorter the logger duration and the more memory is required. Once you launch the logger, the selected statistics will be displayed on the logger LCD. After you set up Burst or Statistics logging, there will be an Edit button next to Logging Mode in the Launch Logger window to make additional changes as necessary. Note that Fixed Interval or Statistics mode is required if you want to set up alarms for the logger.
Logging Duration. This lists the approximate time it will take to fill the logger memory based on the logging interval and sensors currently selected. This is a theoretical estimate only; battery life and other factors will affect your deployment.
Start Logging. Select when to launch the logger. This defaults to the setting for the logger's previous launch (you can change this in HOBOware Pro with the Launch Time-Saving Options subcategory of the General preferences). You can choose to launch this logger:
Now. Logging begins as soon as you click the Start button.
At Interval. Logging will begin at an exact interval (for example 9:00:00 rather than 8:47:00 when
you choose a one-hour logging interval). The exact start time depends on the logging interval you choose.
Push Button. Logging will not start until you press the button on the logger and hold it down for at
least three seconds. The Waiting LED will blink on the logger until you press the Start/Stop button.
On Date/Time. Logging will begin at a date and time you specify, up to approximately six months
from the present. The LCD screen will count down to that start date/time and then logging will begin.
Stop logging. Select when you want the logger to stop logging. You can choose:
When memory fills or Never (wrap when full). If you select "When memory fills," then the logger
will stop recording data once the memory is full. If you select "Never (wrap when full)," the logger will record data continuously until either the logger battery runs out or you stop it. Once the logger is full, the newest data will overwrite the oldest data.
Push button. When this option is selected, the logger will stop recording data when you press the
Start/Stop button on the logger itself for 3 seconds. If you also configured a Push Button start, then you must wait 5 minutes after logging begins before you can use the button to stop logging.
Allow button restart. This setting is available when "Push button" is selected as a "Stop Logging"
option. If you select this option, you can resume logging on the next even logging interval on a stopped logger by pressing the Start/Stop button for three seconds. For example, press the Start/Stop logging button on the logger once to stop logging. Then, a few minutes, hours, or even days later when you are ready to continue logging, press the Start/Stop button on the logger again and logging will resume at the next even logging interval (i.e. if the logging interval is set at 1 hour and you press the button at 10:15 AM, logging will not resume until 11:00 AM, which is the next even interval based on the 1-hour logging interval). You can then continue to start and stop logging as often as you'd like during this same deployment. Any gaps between when you stopped and restarted logging during this deployment will be reflected on the plotted data when you read out the logger. Once you relaunch the logger, a new deployment and datafile will begin. The data from the previous deployment will not be carried over to the new one.
Specific stop date. Select the date you want the logger to stop recording data. Choose either a
preset time or set your own custom date and time.

RMS Voltage (V). RMS is root mean square. True RMS is the real or effective value of AC voltage for a circuit.
RMS Current (A). True RMS is the real or effective value of current for a circuit.
Active Power (W). The capacity of the circuit for performing work in a particular time (also known as
real power).
Active Energy (Wh or kWh). A watt-hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. kWh is a unit of energy equal to 1,000 watt-hours.
Apparent Power (VA). The product of the current and voltage of the circuit.
1-800-LOGGERS 30 www.onsetcomp.com
Page 31
HOBOware User’s Guide
Power Factor (PF). The ratio of the active or real power flowing to the load to the apparent power in the circuit. It is a dimensionless number between 0 and 1.
2. Type a label for each enabled measurement, if desired.
3. Select the Max, Min, or Avg checkboxes (if available) to log statistics for each enabled measurement. The logger will calculate maximum, minimum, and average values at each logging interval based on the logger's fixed single-cycle sampling rate of 60 Hz or 16.67 mS. For example, at a 1-minute logging interval, the statistics would be based on 3,600 samples (60 Hz x 60 seconds). This will result in up to three additional series per channel that record the following information at each logging interval:
The maximum, or highest, sampled value,
The minimum, or lowest, sampled value, and
An average of all sampled values.
Statistics are not available for Active Energy (kWh).
Notes on configuring measurements:
If statistics were configured, press the Next/Clear button on the logger for 1 second to cycle through
the maximum and minimum values (as applicable) on the LCD screen. Average is not available for viewing on the LCD screen. Note that the maximum and minimum values displayed are not the values recorded at the logging interval. They are based on samples taken every 16.67 mS during the entire logging period. To reset the starting point used to determine the maximum and minimum values shown on the LCD screen, press and hold the Next/Clear button for 3 seconds. See the logger manual for more details.

On Date/Time. Logging will begin at a date and time you specify, up to approximately six months
from the present.

Launch Options for the HOBO U30 and Other Station Loggers
The following launch options are available for Station loggers, which connect to the computer via serial cable instead of USB cable. Note that the Launch Logger window may vary from the example shown below.
Logger Information
Name.
Enter a name for the launch, up to 40 characters, in this field. This name is used as the default file name when you read out and save the data recorded by the logger. It is also the default title of the plot.
Serial Number. This is the serial number for the logger. Note that some external sensors also have
serial numbers, which are listed in the Sensors pane.
Deployment Number. This is the number of times (including this time) the logger has been
launched. Each time you start a new launch, the deployment number increases by one.
Battery Level. This shows the current battery level in the logger.
User Notes. Click this button to type up to 2000 characters of information about the deployment.
This text will be displayed in the Details pane after you read out the logger and plot the data.
Status. Click the Status button to check the logger settings from the previous launch.
Sensors
Only the sensors that are currently plugged in or built into the logger are listed. Sensors are listed in ascending order by serial number, regardless of their physical position in the logger. If you add or remove sensors, click the
Refresh button to make sure your changes are seen by the logger and displayed in this list.
1-800-LOGGERS 38 www.onsetcomp.com
Page 39
HOBOware User’s Guide
You can assign a name to each sensor (up to 30 characters). This is helpful if you want to specify a location where the sensor will be placed or if you need to differentiate multiple sensors of the same type.
Sensors must be connected prior to launching if you will be entering a name for the sensor or configuring FlexSmart modules or Analog Sensor Ports (use the Configure button to the right of the Label field). Otherwise, sensors do not have to be connected when setting up the launch. You may set up the launch for a delayed or push button start, then connect the sensors later before logging begins.
Notes about configuring sensor channels:
Do not attach more than 15 channels of sensors. The logger cannot accommodate more than 15
channels.
In addition to logging up to 15 channels, the HOBO Energy Logger and HOBO U30 Station can record
their internal battery channel (other sensors must be attached; the logger cannot log battery alone). When enabled, the logger's battery voltage is recorded at each interval. The battery voltage is logged by default for the U30-GSM, U30-WIF, and U30-ETH and is an option for other logger models.
Always enable the logger's internal battery channel when logging with excitation power. This will help
you determine whether and when excitation power was turned off during a deployment.
HOBOware Pro Data Assistants let you create new data series by combining data recorded by the
logger with additional data. When you use a Data Assistant from the Launch Logger window, the parameter set is saved and applied to data every time you read out a logger or open the resultant data file. The derived data is also shown when you check the latest readings in the Status window. You can use the following Data Assistants from the Launch window (others can only be used from the Plot Setup window): Pulse Scaling, Linear Scaling, and kWh (HOBOware Pro only). This feature is available for the HOBO U30, the HOBO H21 (Weather Station and Micro Station) and the HOBO H22 (Energy Logger) loggers. Click the kWh or Scaling button to access the Data Assistants window. Select the desired assistant and click the Create button to run the selected assistant. After you enter values, click Save. Sensors that support Data Assistants at launch time display the Scaling and/or kWh icon next to their name.
Click the Filters button to create an additional filtered series, such as average temperature per day,
Note that labels do not apply to calculated or derived channels, such as filtered series.
Deployment
Logging Interval.
Sampling Interval. The sampling interval allows you to take multiple measurements within the
Logging Duration. This lists the approximate time it will take to fill the logger memory based on the
automatically when you read out the logger and plot the data.
Select how often the logger will record data. You can choose either one of the preset logging intervals or specify a custom logging interval. The minimum logging interval is one second and the maximum for most loggers is 18 hours, 12 minutes, and 15 seconds. The shorter the logging interval, the more quickly memory fills and battery power is consumed. Some sensors (specifically, the FlexSmart TRMS modules) require a logging interval of two seconds or greater. If you choose a faster logging interval, erroneous data will be logged on these channels.
logging interval, then average them together to create a single logged measurement. The sampling interval is optional and is valid only for sensors that support measurement averaging. Refer to the sensor's user manual to determine whether measurement averaging is available on the sensor. If you have at least one sensor that supports measurement averaging, click the Enable button, then set the sampling interval at less than or equal to the logging interval (up to four minutes). Rapid sampling (faster than one minute) will reduce the logger's battery life. If you do not have any sensors with measurement averaging or wish to turn off the sampling interval, click the Disable button.

and events, no estimation is possible. If you add or remove sensors while viewing the Launch window, click the Refresh button to get an updated Logging Duration.
Start Logging. Select when to launch the logger. This defaults to the setting for the logger's previous
launch (you can change this in HOBOware Pro with the Launch Time-Saving Options subcategory of the General preferences). You can choose to launch the logger:
Now. Logging begins as soon as you click the Start button. If you do not have at least one sensor
attached, the logger will not launch.
At Interval. Logging will begin at an exact interval (for example 9:00:00 rather than 8:47:00 when
you choose a one-hour logging interval). The exact start time depends on the logging interval you choose.
Push Button. Logging will not start until you press the button on the logger and hold it down for at
least three seconds. If the logger has a light, it will flash quickly when logging begins. This is not available for the U30 Station.
On Date/Time. Logging will begin at a date and time you specify, up to approximately six months
from the present.
Save Settings in Logger. Logging will not start, but the launch settings will be saved so that you do
not have to re-enter them when you are ready to launch at a later time. The next time you view the Launch window for this logger, the settings you entered will still be in place.
Stop Logging. There are two options for stopping the logger: either "when memory fills" or "never
(wrap when full)." If you select "when memory fills," then the logger will stop recording data once the memory is full. If you select "never (wrap when full)," the logger will record data continuously until either the logger battery runs out or you stop it. Once the logger is full, the newest data will overwrite the oldest data.
Skip launch window next time (HOBOware Pro)
Check this box if you would like to bypass the Launch Window the next time you choose Launch from the Device menu or click the Launch icon. This will cause the next logger to be launched with either the previous launch settings or the current logger settings as set in the Launch Time-Saving Options subcategory of the General preferences.
Note: For additional details on launching the HOBO U30 Station, see Working with the HOBO U30 Station.
Multiple Logging Intervals
Some loggers can be configured with multiple logging intervals, which allow you to define separate intervals for different phases of the deployment.
To configure multiple logging intervals:
1. From the Device menu, select Launch.
2. In the Launch Logger window, click the Add New Interval button for each interval you wish to add (the maximum number of intervals allowed varies by logger model). If there is no Add New Interval button, then the logger does not support multiple logging intervals.
3. Set the hours, minutes, and seconds for each interval, and the number of samples you want the logger to record at each interval.
4. Use the Start and End times in the Duration column to decide how many samples to record at each interval. logger's memory, the number of samples and end times are only estimates. Frequent events will cause the logger to fill up sooner.

Page 41
HOBOware User’s Guide
5. Set any other launch options and click Start.
To delete an interval, click the Remove button next to the interval in the Launch Logger window.
Fast Logging Intervals
Some loggers can be configured with fast logging intervals, which allow you to log more than once per second, up to 100 measurements per second (hertz).
To use fast logging intervals:
1. From the Device menu, select Launch.
2. In the Launch Logger window, click the Fast button. If there is no Fast button, then the logger does not support fast logging intervals.
3. Choose a logging frequency from the Hertz drop-down list or enter the logging interval in decimal form in the Sec field.
4. Set any other launch options and click Start.
Notes:
A logger cannot communicate with a computer or shuttle while it is logging at a fast interval. The logger will stop logging if you connect the logger to a computer, base station, or shuttle while it is logging in fast interval mode.
Be aware that a fast logging interval typically means a very short logging duration. Make sure the
logger will run long enough to collect the data you need. Disabling unnecessary channels can extend the logging duration and help to compensate for decreased duration while operating in fast interval mode.
Because fast logging deployments are so brief, the logger must be launched with a coupler or button
start. Follow the instructions that came with your logger for a trigger (coupler or button) start. If the logger has a light, it will flash quickly when logging begins.
Setting a Default Action on Multiple U-Series Devices
By default, HOBOware does not take any action when you connect a device. You can change this behavior by setting a default action to Launch, Readout, or Get Status. This can save you time when working with multiple loggers of the same type. Note: This feature is only available with HOBOware Pro and U-Series loggers.
To set a default action:
1. From the Device menu, select Default Action.
2. Select Launch, Readout, or Get Status.
If you set the default action to launch, you can also change the preferences to automatically populate the Launch Logger window with the same settings as the previous launch. This is helpful if you are launching numerous loggers of the same type with the same settings. To set this preference:
1. Select Preferences from the File menu in Windows or the HOBOware menu in Macintosh.
2. Select General and then select Launch Time-Saving Options.
3. For the "Fill launch window with contents of" setting, select Previous Launch.
4. Click OK.
1-800-LOGGERS 41 www.onsetcomp.com
Page 42
HOBOware User’s Guide
When a device is connected, the default action you set will take place automatically. For example, if you chose Readout, HOBOware Pro will read out the logger immediately. You can then disconnect that logger, connect another logger, and the next logger will be read out automatically. If you connect a shuttle, the shuttle's new files will be offloaded automatically. Similarly, if you chose Launch for the Default Action, the Launch Logger window will open automatically when you connect the logger. The next time you connect a logger of the same time, the Launch Logger window will open automatically and be populated with the previous launch settings if you configured the Launch Time-Saving Options in the Preferences. A note will appear in the Launch Logger window when this preference is in use.
Important Note for Windows: The first time you connect a device, the Default Action may not be triggered. After the device has been connected to the computer and disconnected at least once, the Default Action should then be triggered.
Using Launch Utilities
There are several utilities available from the Launch Logger window for setting up customized data series, configuring alarms, and setting advanced logger options. These utilities vary depending on the type of logger you are using. They include:
Scaling
Filters
Alarms
Advanced Sensor Properties: Pulse Frequency and Lockout Time
Advanced Sensor Properties: Calibration
Advanced Sensor Properties: Occupancy
Statistics: Maximum, Minimum, Average, and Standard Deviation
Filtered Series vs Statistics Logging
Burst Logging
Filter Series at Launch
As part of the launch setup, you can create a filtered series that automatically calculates additional values, such as maximum, minimum, average, or total, for a set interval upon readout of the logger. The filtered series is saved as an additional series in the datafile so it is always available when plotting your data. This saves you the time of manually filtering data for each series after readout using the regular HOBOware filter tool, although this tool is still available should you need to further filter data later.
To set up a filtered series at launch:
1. Select the channel, or sensor type, you wish to filter.
2. Select the type of filter and the interval you wish to use. If you select an interval of week or month, select "First data point" for the filter to start on the date and time of the first logged data point or select the day of the week or month you want the filter to start (the filter will start at midnight on the
1-800-LOGGERS 42 www.onsetcomp.com

HOBOware User’s Guide
day selected). In this example, the type of filter is "Average Temperature" in each month starting with the first data point. Note that filters vary depending on the channel's measurement type.
3. Edit the Resultant Series Name as desired. Click
4. The newly created series is added to the Filtered Series list as shown below. To make a change to a filtered series, either double-click the series name or select the series name and click Edit. To delete a filtered series, select the series name and click Delete.
Create New Series.
5. Repeat steps 1 through 4 to create additional filtered series. Not only can you create filtered series for all channels, but you can also create multiple filtered series on a single channel (for example, you can show the maximum, minimum, and average temperature for a single temperature channel).
6. Click
7. After you launch the logger and read it out, the filtered series will automatically be listed in the Plot

Filtered Series vs. Statistics Logging
Data Assistants Window (Scaling)
When you run a Data Assistant from the Launch Logger window, you can create a derived series, which is an additional data series automatically calculated each time you read out the logger. The Data Assistants window lists only those assistants available for the currently selected sensor and logger at launch time. There may be other Data Assistants available for use after reading out the logger.
To set up a derived series with a Data Assistant:
1. Select the Data Assistant you wish to use and click Create.
2. Select the information, or scaling parameters, you want the series to contain and click Save.
3. The new series appears in the My Derived Series list. Create additional series as desired.
To make a change to a derived series, either double-click the derived series name or select it and then click Edit.
To delete a derived series, select the series and then click Delete.
4. After you have finished creating or editing the derived series, click Done. Depending on the type of logger you are using, the total number of derived series created appears on the kWh and/or Scaling buttons in the Launch Logger window. Derived series are also listed in the Status window.
After you launch the logger and read it out, the derived series will automatically be listed in the Plot Setup dialog, from which you can select the series you wish to plot.
Notes:
Loggers launched in HOBOware 3.2 with series created by the Pulse Scaling, Linear Scaling, and kWh
Data Assistants or with filtered series cannot be read out in earlier versions of HOBOware.
When setting up kWh or scaling for UX90 series loggers, the scaled series information will appear on
the LCD screen on the logger. In addition, only the Energy series appears on the LCD screen when configuring kWh. Average power and cost series will not display on the screen; they are available in HOBOware only.
Although it is possible to set up more than one scaling value for each sensor on the HOBO 4-Channel
Analog logger (UX120-006M), only the first scaling value for that sensor will be used.
Configure Alarms
You can set an alarm to trip when a sensor reading rises above or falls below a specified value on certain logger models. Note: The U30 Station also has alarms capability; see Setting Alarms on a HOBO U30 Station for more details.
To set an alarm:
1. If the Alarms window is not already open, click the Alarms button from the Launch Logger window. If there is no Alarms button, then the logger does not have alarm capability. If the Alarms button is disabled, be sure you have enabled logging on a sensor that supports alarms. If the Alarms button is disabled for MX, UX100, or UX120 series loggers, make sure the Logging Mode is not set to Burst.
1-800-LOGGERS 44 www.onsetcomp.com
Page 45
HOBOware User’s Guide
Alarms are not available for these loggers when the Logging Mode is set to Burst in the Launch Logger window.
2. In the Alarms window, select the sensor that you want to have an alarm. Note: The example below is for a UX100 series logger. Any differences for other logger models are noted in these steps.
3. Select the High Alarm checkbox if you want an alarm to trip when the sensor reading rises above the high alarm value. Type the reading next to the High Alarm checkbox or drag the red upper slider. In this example, we've set an alarm to trip when the temperature rises above 85°F.
4. Select the Low Alarm checkbox if you want an alarm to trip when the sensor reading falls below the low alarm value. Type in the reading next to the Low Alarm checkbox or drag the blue lower slider. In this example, we've set an alarm to trip when the temperature falls below 32°F.
Note: The actual values for the high and low alarm limits are set to the closest value supported by the logger. For example, the closest value to 85°F that the UX100 series logger can record is 84.990°F and the closest value to 32°F is 32.043°F. In addition, alarms can trip or clear when the sensor reading is within the logger specifications of 0.02°C resolution. This means the value that triggers the alarm may differ slightly than the value entered. For example, if the High Alarm is set to 75.999°F, the alarm can trip when the sensor reading is 75.994°F (which is within the 0.02°C resolution).
5. Set the duration for out-of-range samples before an alarm is tripped.
6. Select either Cumulative or Consecutive for the Sensor Alarm Mode (select logger models only). If you select Cumulative, then the alarm will trip when the time the sensor is out of range over the course of the deployment is equal to the selected duration. If you select Consecutive, then the alarm will trip when the time the sensor is continuously out of range is equal to the selected duration. For example, the high alarm for temperature is set to 85°F and the duration is set to 30 minutes. If Cumulative is selected, then an alarm will trip once a sensor reading has been at or above 85°F for a total of 30 minutes since the logger was configured; specifically, this could be 15 minutes above 85°F in the morning and then 15 minutes above 85°F again in the afternoon. If Consecutive is selected, then an alarm will trip only if all sensor readings are 85°F or above for a continuous 30-minute period.
7. Choose how long the logger should maintain the sensor or visual alarm once it has tripped (select logger models only). Select "Host has relaunched logger" if you want the alarm to remain visible on the LCD until the next time you relaunch the logger. Select "Sensor reading within limits" if you want the
1-800-LOGGERS 45 www.onsetcomp.com
Page 46
HOBOware User’s Guide
alarm to clear once the sensor reading returns to the normal range between the high and low alarm limits. Select "Cleared with button press" if you want the alarm to remain on and visible on the LCD until you press the Alarm button on the logger (select logger models only).
8. U14-00x loggers only: You can set the Relay Contacts to Normally Open or Normally Closed as described in the logger manual. Click the Test Set Alarm button to test the relay switches. Deselect the "Set Alarm on Low Battery" checkbox if you do not want an alarm to trip when the logger's battery is running low.
9. MX1102 loggers only: You can select Use Audible Alarm if you want a beep to sound on the logger every 30 seconds when the sensor alarm trips. The beeping will continue until the alarm is cleared from the software, a button on the logger is pressed, or 7 days have passed. Battery life will be slightly reduced when this setting is enabled. It is recommended that you only enable this feature if you have regular access to the logger so that you can easily turn off the beeping.
10. Click OK to save the alarm settings and return to the Launch Logger window.
Once the logger is launched, alarms will trip as determined by these settings. For UA-001 loggers, a "high" or "low" LED will blink when an alarm is tripped; alarms are checked at every logging interval. For other models, logger alarms will display on the LCD screen. The alarm limits are checked when the logger's LCD screen refreshes. See the logger manual for details on LCD screen refresh rates.
When you read out the logger, high and low alarm levels will be displayed on the plot. In the example below, the temperature rose above 85°F so those readings are in the red, or high alarm, portion of the plot. The temperature never fell below the low alarm limit, which is the blue portion at the bottom of the plot. Some logger models also display alarm events showing when the alarm tripped (and cleared if applicable). In this example, there are "Chan 1 Alarm Tripped" and "Chan 1 Alarm Cleared" events showing when the temperature alarm tripped and cleared. The "Chan 1 Alarm Cleared" event contains the value that was furthest out of range for the sensor before the alarm cleared (see the Points table for the actual value).
Advanced Sensor Properties: Pulse Frequency and Lockout Time
Use the Advanced Sensor Properties window to set the maximum pulse frequency for raw pulse channels and to specify a lockout time for raw pulse and event channels, which prevents false readings from mechanical sensors as their relay state changes.
Setting maximum pulse frequency is not required, but it can help optimize logging duration. The maximum pulse frequency, multiplied by the logging interval, determines the maximum count of pulses possible within each interval. The logger then can use this value to adjust the amount of memory (bits) used to log each data point. This means the logger uses memory as efficiently as possible, which in turn maximizes logging duration.
1-800-LOGGERS 46 www.onsetcomp.com
Page 47
To configure maximum pulse frequency and lockout time:
1. Select the sensor that corresponds with the pulse channel you wish to configure.
2. Set the maximum pulse frequency, which controls how many pulses per second can be processed by the logger on a single pulse channel. The option to set the maximum pulse frequency is only available for raw pulse channels (sensors for which you have selected Raw Pulse as the sensor type in the Launch Logger window). Refer to the specifications in your sensor or device documentation for recommended maximum pulse frequency values. In general, the larger the maximum pulse frequency, the shorter the logging duration will be for the deployment. Note that the pulse frequency ranges in this window vary depending on the logger model.
HOBOware User’s Guide
3. Click the "Apply lockout time" checkbox if you wish to specify a time period when pulses will be ignored. Select the lockout time value from 1 to 10. On sensors with both pulse frequency and lockout time settings, lockout time will affect the maximum pulse frequency: the higher the lockout time, the lower the maximum pulse frequency will be.
Notes:
If the logger has multiple sensors, then all sensors will have the same lockout time. This means if
you are using multiple sensors with different lockout time requirements, this may result in lost pulses or false pulses.
Lockout time is only available for raw pulse channels and event channels.
When lockout time is enabled, you can specify a value from 1 to 10 (with a default of 5), which is
then multiplied by 100 milliseconds for a range of 0.1 to 1 second. The available range for the maximum pulse frequency is automatically recalculated based on the lockout time. For example, if the lockout time is set to 2, the maximum pulse frequency range changes to 0.01 to 5 Hz. The maximum pulse frequency also varies depending on the logger model. Refer to the specifications in the logger documentation for maximum pulse frequency (documentation is also available at http://www.onsetcomp.com/support/manuals).
4. Click Save. Note that the selections will not take effect in the logger until you launch it.
Advanced Sensor Properties: Calibration
Use the Advanced Sensor Properties window to set the calibration method used for internal light or motor sensors in UX90 series data loggers. The default calibration method is to "calibrate from logger," which is an auto­calibration procedure using the Calibrate button on the logger. Alternatively, you can set the calibration method to a maximum or minimum sensitivity level as defined by HOBOware. To change the calibration method:
1. Select the sensor that corresponds with the internal light/motor channel you wish to configure.
2. Select "Calibrate from logger" to use auto-calibration or select "Set to maximum or minimum sensitivity" to use HOBOware for calibration. See below for more details on both procedures.
1-800-LOGGERS 47 www.onsetcomp.com
Page 48
HOBOware User’s Guide
3. Click Save. Note that the selections will not take effect in the logger until you launch it.
Calibrate from Logger
Calibrating from the logger with the calibration button, also called auto-calibration, is used to calibrate the ON and OFF threshold of the logger to achieve reliable readings in an environment where motor or light levels are unknown prior to deployment or where logger light levels are variable. In the auto-calibration process, the light level or the AC magnetic field for a motor sensor is measured via a built-in analog-to-digital converter and the resulting value is used to generate a calibration threshold.
The logger has a built-in hysteresis level of approximately 12.5% for the light sensor and 6.25% for the motor sensor to prevent the sensor from toggling between ON and OFF when the signal level is near the calibration threshold. This plot shows how the logger handles hysteresis. The logger interprets the signal as ON until it drops below the lower level of the calibration threshold. Once it switches to off, the signal will not switch back to ON until it bypasses the upper limit of the calibration level.
When auto-calibrating from the logger (button calibrating):
1. Deploy the logger near the light/motor to be monitored. Turn the light or motor on.
2. Press the Calibrate button for 1 second. The LCD screen will display the signal strength of the light/motor. The signal strength should ideally be at least 3 bars. Orient the logger as necessary to increase the signal strength. The signal strength indicator will remain on the display for ten minutes or until calibration is complete.
3. Press the Calibrate button for 3 seconds while “HOLD” appears on the LCD screen. For the light sensor, move your hand away from the logger to prevent shadowing. The logger will count down to the auto­calibration and then display either “PASS” or “FAIL” after calibration is complete.
1-800-LOGGERS 48 www.onsetcomp.com
Page 49
HOBOware User’s Guide
4. If the auto-calibration fails, point the sensor directly at the light or position it closer to the motor source and then repeat these steps.
Set to Maximum/Minimum Sensitivity
If you cannot manipulate the light source or access the motor, you can set the calibration level in this window. The lower the light/magnetic field level, the higher the sensitivity needs to be to record changes between ON and OFF conditions. For light sensors, the maximum sensitivity is approximately 100 lux (for rooms with low light levels, such as residential environments) and the minimum sensitivity is approximately 500 lux (for rooms with high light levels, such as retail environments). For motor sensors, the maximum sensitivity is approximately 40 mG (for a weak magnetic field) and the minimum sensitivity is set to approximately 100 mG (for a strong magnetic field).
Advanced Sensor Properties: Occupancy
Use the Advanced Sensor Properties window to set the timeout value for an occupancy sensor (UX90-005x/006x models). The timeout value is the period of inactivity required for the sensor to consider the area unoccupied. The timeout value is set to 1 minute by default. You can change this to one of the preset values or enter a custom value.
To change the timeout value for an occupancy sensor:
1. Select the sensor that corresponds with the occupancy channel you wish to configure.
2. Select a preset timeout value as shown in the example below or select Custom and enter your own value in minutes and seconds.
3. Click Save. Note that the selections will not take effect in the logger until you launch it.
Statistics: Maximum, Minimum, Average, and Standard Deviation
You can configure UX100 series and some UX120 series loggers to calculate maximum, minimum, average, and standard deviation statistics for all enabled sensors during logging at each logging interval based on samples taken at a rate you specify. This will result in up to four additional series per sensor that record the following information at each logging interval:
The maximum, or highest, sampled value,
The minimum, or lowest, sampled value,
An average of all sampled values, and
The standard deviation from the average for all sampled values.
For example, let’s say both the temperature and RH sensors have been enabled, the logging interval is set to 5 minutes and the sampling interval is set to 30 seconds (with maximum, minimum, average, and standard deviation all enabled). Once logging begins, the logger will measure and record the actual temperature and RH sensor values every 5 minutes. In addition, the logger will take a temperature and RH sample every 30 seconds and temporarily
1-800-LOGGERS 49 www.onsetcomp.com
Page 50
HOBOware User’s Guide
store them in memory. The logger will then calculate the maximum, minimum, average, and standard deviation using the samples gathered over the previous 5-minute period and log the resulting value(s). When reading out the logger, this would result in 10 data series (not including any derived series, such as dew point): two sensor series (with temperature and RH data logged every 5 minutes) plus eight maximum, minimum, average, and standard deviation series (four for temperature and four for RH with values calculated and logged every 5 minutes based on the 30-second sampling).
Notes:
Statistics are not available for logging if Normal or Burst has been chosen as the Logging Mode in the
Launch Logger window.
On thermocouple loggers, statistics are only available on thermocouple channels and not on the
internal temperature channel.
Maximum, minimum, and average statistics can be logged for a HOBO Plug Load logger (UX120-018),
but they are configured differently than the following steps for the UX100 series and other UX120 series loggers. In addition, average statistics are not displayed on the LCD screen for this logger. The maximum and minimum values displayed are based on the entire deployment. See Launch Options for a HOBO Plug Load logger (UX120-018) for details.
To configure statistics:
1. If the Statistics window is not already open, select Statistics from the Logging Mode drop-down menu in the Launch Logger window. Or, if Statistics has already been configured, click the Edit button.

Once logging begins, press the Alarm/Stats button on the logger for 1 second to cycle through the current maximum, minimum, average, and standard deviation data (as applicable) on the LCD screen (it is not available in the HOBOware Status window). You can plot the statistics series once you read out the logger.
Filtered Series vs. Statistics Logging
Some logger models support filtered series and statistics logging, both of which involve calculating maximum, minimum, and average values that you can plot after the logger is read out. Both are accessed from the Launch Logger window (for filtered series, click the Filters button; for statistics logging, select Statistics as the Logging Mode or for a UX120-018 logger, select the Max, Min, and Avg checkboxes for each sensor). However, there are some key differences between the two features. Essentially, statistics logging is performed at the sampling interval of the logger while filters include data accumulated from a series of logged data points.
The following table compares filtered series to statistics logging so that you can choose the best solution for your deployment. Note: There is also another filtering option available after you read out the logger, which is available from the Filter button on the toolbar. This allows you to create filtered series based on the data in the plotted datafile. For more information on filtering after reading out a logger, see Filtering a Series.

less memory as every sample is not
recorded.
For UX120-018: Data is sampled at
an internal logger rate and statistics
are logged at each logging interval.
Burst Logging
Burst logging is a logging mode available for UX100, MX, and some UX120 series loggers that allows you to set up more frequent logging when a specified condition is met. For example, let's say the logger is recording data at a 5­minute logging interval and burst logging is configured log every 10 seconds when the temperature goes above 85°F (the high limit) or falls below 32°F (the low limit). This means the logger will record data every 5 minutes as long as the temperature remains between 85°F and 32°F. Once the temperature reaches 90°F, for example, the logger will switch to the faster logging rate and record data every 10 seconds until the temperature falls back below the high limit (or 85°F in this case). At that time, logging then resumes every 5 minutes at the normal logging interval. Similarly, if the temperature falls to 30°F, for example, then the logger would switch to burst logging mode again and record data every 10 seconds. Once the temperature rises back to 32°F, the logger will then return to normal (fixed interval) mode, logging every 5 minutes.
Notes:
Burst logging is not available if alarms have been enabled for the logger.
The Stop Logging option "Never (wrap when full)" is not available when burst logging is configured.
The actual values for the burst logging limits are set to the closest value supported by the logger. For
example, the closest value to 85°F that the logger can record is 84.990°F and the closest value to 32°F is 32.043°F.
Burst logging mode can begin or end when the sensor reading is within the logger specifications of
0.02°C resolution. This means the value that triggers burst logging may differ slightly than the value entered. For example, if the High Limit for a temperature alarm is set to 75.999°F, burst logging can start when the sensor reading is 75.994°F (which is within the 0.02°C resolution).
Once the high or low condition clears, the logging interval time will be calculated using the last
recorded data point in burst logging mode, not the last data point recorded in normal or fixed interval mode. For example, let's assume the logger has a 10-minute logging interval and logged a data point at 9:05. Then, the high limit was surpassed and burst logging began at 9:06. Burst logging then continued until 9:12, when the sensor reading fell back below the high limit. Now back in normal (fixed interval) mode, the next logging interval will be 10 minutes from the last burst logging point, or 9:22 in this case. If burst logging had not occurred, the next data point would have been at 9:15.
A New Interval event will appear on the plot (if you select events for plotting in the Plot Setup
window) each time the logger enters or exits burst logging mode.
On thermocouple loggers, burst logging is only available on thermocouple channels and not on the
internal temperature channel.
1-800-LOGGERS 52 www.onsetcomp.com
Page 53
To set up burst logging:
1. If the Burst Logging window is not already open, select "Burst logging" from the Logging Mode drop­down menu in the Launch Logger window. Or, if Burst logging has already been configured, click the Edit button.
2. Select the sensor you want to configure for burst logging.
3. Select the High Limit checkbox if you want to set up a condition in which burst logging will occur when the sensor reading rises above the high limit value. Type in the value or drag the red upper slider.
4. Select the Low Limit checkbox if you want to set up a condition in which burst logging will occur when the sensor reading falls below the low limit value. Type in the value or drag the blue lower slider.
In this example, both the high and low limits were selected. You may choose only one if you wish.
HOBOware User’s Guide
5. Set the burst logging interval, which must be less than the logging interval. Select either a preset burst logging interval or select Custom and enter your own interval. Keep in mind that the more frequent the burst logging rate, the greater the impact on battery life and the shorter the logging duration.
6. Click OK when done. This will return you to the Launch Logger window. Click the Edit button next to Logging Mode in the Launch Logger window to make additional changes.
Once the logger is launched, the high and low burst logging levels are only checked when the logger's LCD screen refreshes once every 15 seconds. Therefore, if you set the logging interval to less than 15 seconds and the sensor reading falls outside the levels, the burst logging will not log until the next 15-second refresh cycle.
Important: If high and/or low limits have been configured for more than one sensor, then burst logging will begin when any high or low condition goes out of range. Burst logging will not end until all conditions on all sensors are back within normal range.
Carbon Dioxide Sensor Settings
The CO2 sensor in the HOBO MX CO2 logger (MX1102) requires altitude compensation and regular calibration to ensure accurate readings are being taken in the location where it is deployed. Both auto and manual calibration are selected by default when first configuring the logger. Altitude compensation should be used if you are
1-800-LOGGERS 53 www.onsetcomp.com
Page 54
HOBOware User’s Guide
monitoring CO2 at elevations above or below 305 meters (1,000 feet). A manual calibration immediately after logging begins is recommended for best accuracy.
The following CO
settings are available:
2
Use manual calibration. Manual calibration is the best way to calibrate your logger. Select this option if you want to manually calibrate the logger to 400 ppm using the Calibrate button on the logger. This requires taking the logger outside in fresh air on a dry day or to an indoor location that is unoccupied and has no connection to a ventilation system for five minutes on a regular basis. This is recommended if the logger is deployed in a building that is always occupied, if you want the logger to be calibrated more frequently than every eight days (the normal auto calibration schedule), or if you want to calibrate the logger immediately after logging begins. Note: Once a manual calibration is performed, the 24-hour auto calibration is canceled and an auto calibration will be performed eight days from the time the manual calibration occurred. (Relaunching the logger resets the 24-hour/8-day auto calibration routine).
Use auto calibration. Select this option if you want the logger to automatically calibrate within the first 24 hours after logging begins and then every eight days thereafter. The logger will be calibrated based on the average of the three CO
measurements that follow the lowest CO2 value identified during the 24-hour or
2
8-day time period as applicable. Important: Accurate auto calibration requires the building or location where the logger is deployed to be empty at least once during the eight-day period (for example, an empty office building during the weekend or overnight will typically have background CO
levels of 400 to
2
450 ppm).
If the logger is deployed in an area where the CO
level does not go down to 400 ppm during the eight-
2
day time period, then manual calibration should be performed regularly instead or inaccurate CO readings will be reported. If you plan on using auto calibration but the building will be occupied during the first day after logging begins, then you can use the manual calibration option as well. You can manually calibrate the logger immediately after logging begins and use auto calibration thereafter. Note: Every time the logger is launched, auto calibration will occur after 24 hours and then again after eight days unless a manual calibration is performed first.
2
Use Carbon Dioxide sensor altitude compensation. Select this option if the logger is deployed at a location above or below 305 meters (1,000 feet). Type the altitude above or below sea level in either meters or feet. In normal use, the CO
measurement will vary by approximately 0.135% of the reading for
2
each mbar change in barometric pressure (the sensor is calibrated at 1,013 mbar). Use altitude compensation when deploying the logger for the best CO
accuracy possible.
2
After you have selected the carbon dioxide sensor settings, click Save. The settings will take effect once the logger is launched.
Notes:
If both auto calibration and manual calibration are selected, the logger will automatically calibrate within 24 hours after logging begins unless a manual calibration occurs during that time period. In addition, when both calibration settings are selected, the eight-day calibration cycle will be reset any time a manual calibration is performed.
When the logger is calibrated, a Manual Calibration or Automatic Calibration event is logged and available in the data file for plotting with a date and time stamp of when the calibration took place.
1-800-LOGGERS 54 www.onsetcomp.com
Page 55
HOBOware User’s Guide
How to manually calibrate the logger:
1. Take the logger outside in fresh air on a dry day where the carbon dioxide level is 400 ppm. You can also use an indoor location for manual calibration if it is unoccupied and is not exposed to a ventilation system.
2. Press the Calibrate button on the logger for 5 seconds until it beeps. The logger will then calibrate for 5 minutes. The CO
and Calibrate symbols on the LCD will flash while the calibration is underway. A time-
2
and date-stamped manual calibration event is logged in the data at the end of the 5-minute calibration sequence.
3. Once the Calibration process is complete, return the logger to its deployment location. Repeat this process at least once every eight days for best accuracy.
For information about launching the logger, see Launch Options for the HOBO MX CO
Logger (MX1102).

Checking Device Status
The Status window displays real-time information about the attached logger, including the current state of the logger, logging start time, current readings, and memory used. You can check the status for a logger whether it is waiting for logging to begin, actively logging (unless it is logging at a fast logging interval), or stopped.
To check the status of a logger:
1. Connect the logger to the computer.
2. Click the Status icon on the toolbar, or select Status from the Device menu. You can also check
the status by clicking the Status button on the Launch window, but this will show details from the previous launch.
This is an example of the Status window. The information displayed varies depending on the logger that is connected. See Status window for details on the type of information displayed.
1-800-LOGGERS 55 www.onsetcomp.com
Page 56
HOBOware User’s Guide
Important: Battery power is drained more rapidly while checking status. Keep this in mind when frequently checking status during a deployment. You can significantly reduce the demand on the battery by adjusting the Screen Refresh Interval to five seconds or higher (not available on all loggers).
The Status Window
The Status window displays the current status of the logger. If you clicked Status from the Launch Logger window, then details from the previous launch is displayed. The Status window is divided into three panes: Device Identification, Device Details, and Current Readings.
Device Identification
The Device Identification pane shows the logger selected for status. It lists the device name and model number, description entered when the logger was last launched (which is also used as the default file name and title in the plot), serial number, and firmware number.
Device Details
The Device Details pane shows detailed information about the logger deployment including the following items. Note that not all of these items are displayed for every logger model.
Battery Level/Battery State. This is the condition of the battery. Consult the logger documentation
for specifics on battery capacity.
Memory Used. This is the percentage of logger memory used so far in the deployment. Consult the
logger documentation for specifics on memory capacity. Note that if the battery died during logging, the Memory Used will be 100% even if only a small amount of the memory was used.
Stops Logging. This displays the date/time or the condition under which the logger will stop logging.
Last Launched. This is the date and time, including the offset to Greenwich Mean Time (GMT), when
the logger was last launched. This is not necessarily the time when the first sample was recorded; it is the time all the launch settings were loaded in the logger.
Delayed Start (if applicable). If the logger has been launched, but is waiting to start on a particular
date/time or at the next interval, the scheduled start time is shown here in local time.
Deployment Number. This is the number of times the logger has been launched, including the most
recent launch.
Logging Interval (if applicable). This is the rate at which the logger was set up to record data. If
multiple logging intervals are available, the interval currently in use (if the logger is logging) will be shown in bold.
Sampling Interval (if applicable). This is the rate at which sensors are sampling data in between
the logging interval.
DO Sensor Cap Information (HOBO U26 Dissolved Oxygen logger only). For HOBO U26
Dissolved Oxygen loggers, the DO sensor cap expiration date, initialization date, and manufactured date is shown. For more details about the DO sensor cap, see Checking Dates for the HOBO U26 Dissolved Oxygen Logger Sensor Cap.
Current Status. This is a message that describes the state of the logger. Messages include:
Awaiting Button/Coupler Start. The logger has been launched with a coupler or push button start
(if available). Press and hold down the button on the logger for three seconds to begin logging, or follow the instructions that came with your logger if it offers a triggered (coupler) start but does not have a button.
1-800-LOGGERS 56 www.onsetcomp.com
Page 57
HOBOware User’s Guide
Awaiting Delayed Start. The logger will begin recording data at a specific time because the logger
was configured to start on a specific date/time or at the next interval.
Launched, Logging. The logger has been launched is actively recording data.
Logger Is Full. The logger has reached its memory capacity and is no longer recording data.
Logger Is Stopped. The logger is not logging, is not full, and is not awaiting a start.
On Hold for Later Launch. The logger has been launched with a Save Settings start (if available).
Logging is not scheduled to begin, but the launch settings have been entered and saved.
Relay is open/Relay is closed. For the HOBO U30 Station, the current state of the relay is also
displayed.
Current States, if applicable. This is the current condition of the logger button(s). Refer to the
logger documentation for details on logger operation, buttons, and interval events.
Current Readings
The Current Readings pane lists the latest measurement for each data series. Sensors that measure state changes do not show current readings. To change the order of series displayed in the Status window, go to the Preferences and select Display and then Series.
You can also set the Screen Refresh Interval for some loggers. This is the frequency the current readings are updated, up to 3,600 seconds (one hour). A higher number results in less drain on the logger's battery.
A Contact HOBOlink button also appears at the bottom of the Status window for the HOBO U30 Station only. Click this button when you want the HOBO U30 Station to connect to HOBOlink. When you click Contact HOBOlink, a confirmation message is displayed. Once you click Yes, the Status screen will close and then the HOBO U30 Station will attempt to connect to HOBOlink within 30 seconds. A warning may appear in the event that a live connection with HOBOlink is already underway.
Notes:
Readings are displayed for all available sensors, even if they are not being logged. Sensors not being
logged are dimmed.
If a logger has channels for external sensors, a description and reading will be given for the external
channels even if no sensors are plugged in.
For event loggers, the event count displayed in Current Readings will always start at zero, even if many
events have already been logged.
Sensor labels (if applicable) are displayed following the sensor name.
For station loggers, the location (if defined) is displayed next to the reading.
If a HOBO U30 Station has an Analog Sensor Port, readings for one or both channels are displayed.
When a Station logger is logging, the last sample taken by the logger at the last interval will be
displayed.
The RSSI (Signal Level) is displayed for the HOBO U30/GSM Station. This helps you determine if there
is enough signal strength in the current location for the HOBO U30 Station to contact a cellular tower for connecting with HOBOlink. Signal level is measured on a scale of 0 to 10, with 0 being no signal, 1 being a weak signal, and 10 being a strong signal
Battery voltage is displayed for some loggers.
For acceleration loggers only, color-coded tilt meters display X, Y, and Z-axis tilt graphically (relative to
vertical, assuming that the only acceleration force on the logger is gravity).

Chapter 3 Reading Out, Plotting, and Analyzing Data
After a logger has recorded data, you can then do the following:
Read out the data from the logger
Plot the data
Modify the plot if desired
Use Data Assistants
Export the data
Import data
Reading Out Data
To retrieve data recorded by a logger, you must read out the logger. Reading out the logger copies data from the logger to your computer, allowing you to save the data and plot it. During readout, the logger continues to record data unless you have stopped it or it is full.
You can also read out many logger types to a shuttle and then offload the datafiles from the shuttle to your computer. See Offloading and Saving Shuttle Files for more details.
To read out a logger to the computer:
1. Connect the logger to the computer.
2. Click the Readout icon logging, confirm whether to stop the logger. Click either Don't Stop or Stop as desired.
3. A progress bar displays while the data is being read out. Once the readout is complete, choose a location and/or a new filename or accept the default location and name to save the data. The default location is:
C:\Documents and Settings\<user>\My Documents\HOBOware
(for Windows XP)
C:\Users\<user>\Documents\HOBOware
(for Windows 7, Windows 8, or Windows 10)
Users/<user>/Documents/HOBOware
(for Macintosh OS X)
on the toolbar or select Readout from the Device menu. If the logger is still
If you save the file to a different folder, that folder will be the new default save location for future readouts.
4. Click Save. Most datafiles have a .hobo extension, but station loggers have a .dtf extension. If you are using HOBOware Pro in secure mode, the file extensions will be .hsec (U-Series loggers) or .dsec (Station loggers).
5. After saving the data, select the sensors and/or events you wish to display in a graph and click Plot. See Plotting Data for more details on the options available when plotting.
1-800-LOGGERS 59 www.onsetcomp.com

HOBOware User’s Guide
Notes:
If you elected to not save the data upon reading out, you can still plot the data. However, this plotted
data will not be saved automatically. You will be prompted to save the datafile upon closing the plot if desired. Or, select Save Datafile from the File menu if you now want to save the data.
Once a logger is read out, the data will remain in the logger memory until the next time the logger is
launched. Logger memory will automatically be erased once the logger is launched again.
You can read out some U-Series loggers when the batteries are low if the logger can be powered by a
USB cable. In this case, a warning appears before the readout begins indicating the battery is very low and that you may experience communications problems. Once the readout is complete, be sure to replace the batteries as suggested.
You can bypass the Save window during the readout process by setting the Readout Time-Saving
Options in the General subcategory of Preferences.
Plotting Data
After you read out a logger or open a saved file, you can plot the data with the Plot Setup window like the following example.
To plot the data:
1. Use the existing description or type a new one. The default description matches the one used when launching the logger and will be used for the plot title.
1-800-LOGGERS 60 www.onsetcomp.com
Page 61
HOBOware User’s Guide
2. Select the series you wish to view on the plot. Click the All or None button to select or deselect all series, or click the checkboxes to select or deselect individual series. Series types can include:
Logged data series, which is a series containing the sensor measurements, state changes, or
statistics (select loggers only) recorded by the logger.
Derived series, which is a series calculated based on one or more logged data series. This could
be an automatically generated series for a measurement type, such as Dew Point when temperature and RH is logged. Or, it could be a filtered or scaled series if you configured a filters or scaling with a data assistant in the Launch Logger window (select loggers only).
Battery voltage, which lists the logger battery voltage recorded at each logging interval.
3. Change the default units for selected series if desired. You can also change the units for a series after it is plotted.
4. Select the internal logger events to view on the plot. Click the All or None button to select or deselect all events, or click the checkboxes to select or deselect individual events. Internal logger events are individually logged occurrences that can be recorded at any time during deployment, regardless of the logging interval. These events can include started or stopped logging, low battery, or an alarm trip. Refer to the logger manual for a complete list of internal events if applicable.
5. Adjust the time zone offset, if necessary. By default, data is shown in the offset used to launch the logger with HOBOware (not a shuttle). To select a different offset, enter the hours offset from GMT (UTC) in decimal form. You may find this useful if you logged in multiple time zones, or if you took the logger to a different time zone after launching it.
6. If data assistants are available, you can use them to create additional series. Select an assistant from the list and click Process to create a new series.
7. Click the Plot button to generate a plot. The plot is drawn and includes a title, a time axis (x-axis), one or more value axes (y-axis), and a legend. The data for each series are listed in a points table above the plot. Details about each series, such as the type of logger and deployment information are listed in the Details pane to the left of the plot. You can show or hide these elements using the View menu. To organize several plots, use the Window menu to switch between Tabbed View, Tile Horizontally, or Tile Vertically.

On some loggers, the Started and Stopped internal events can only occur once. However, UX100 series
loggers can start and stop logging multiple times in a single deployment (as configured in the Launch Logger window). Multiple stopped and started events in a single file are not only displayed on the plot if selected in the Plot Setup window, but the resulting gap that occurs in the data is also represented in the series. In this example, the logger was stopped at 1:19 and then started again at 2:35; both events are on the plot. The temperature series shows a break between those two times. That represents the gap between when logging was stopped and when it resumed, both using the button on the logger.
Opening Files
HOBOware can open .hobo files from HOBO data loggers, .hproj HOBOware project files, and .dtf files from the HOBO U30 Station, Weather Station, Micro Station, or Energy Logger. The following files can be opened by HOBOware Pro:

Working with Plots
There are several tools available for working with plots.
Tools
There are five tools available on the toolbar for viewing the plot and isolating data.
Use the Arrow tool to point to and select items on the graph to edit their properties (through a right-
click menu).
Use the Crosshair tool to zero in on a specific date and time in the plot and any data points associated
with that date and time. Click the Crosshair icon and then place your cursor anywhere on the plot to draw a red vertical line at a particular point.
Use the Hand Drag tool to move different areas of the graph into view (panning) or adjust the position
of one series so it can be viewed more easily. This is particularly useful when you are zoomed into the
1-800-LOGGERS 64 www.onsetcomp.com
Page 65
graph and want to see another section of the graph without zooming out and then zooming back in on the new location.
Use the Zoom tool to focus on one area of the graph, allowing you to see more detail.
Use the Subset Statistics tool to view statistics for a particular time span (HOBOware Pro only).
Actions
Use the Actions buttons on the toolbar to perform a number of actions on a plot or a series.
Use the Zoom In/Zoom Out buttons to keep the plot centered as you zoom.
Click the Grow Graph at Full Scale button to return to the original, full-scale version of the plot when
the datafile was first opened.
HOBOware User’s Guide
Click the Open Properties button to open the properties window the plot element that is currently
selected, such as axis, series, legend, or title.
Use the Gridline buttons to toggle all horizontal or vertical gridlines on and off. You can also toggle
gridlines on and off for each axis individually. Using the arrow tool, double-click an axis to get the Axis Properties window. Select or deselect the Show Gridlines checkbox to toggle the gridlines for that axis.
Click the Point Markers button to toggle the point markers for all series on and off. To show or hide
markers for an individual series, right-click the series to open the Series Properties window. Select or deselect the Mark Points checkbox to toggle the markers for that series.
Click the Convert Units button to open the Convert Plot window, which allows you to convert the units
on certain series on the plot to other units (for example, from degrees Fahrenheit to degrees Celsius).
Click the Filter Series button the Filter Series window, which allows you to add a statistical series to
the plot.
Click the Pie Charts button if a pie chart is available for the plot (only available on loggers that support
state series)
Click the Add Graph Label button to open the Graph Label Properties window.
Menus
Use the Edit and View menus to access various controls when working with a plot. You can also right-click an element in the plot to access many of the same options available from the Edit and View menu and to open properties windows.
Using the Arrow Tool
Use the Arrow tool to select items on the plot. Click the Arrow icon on the toolbar or press A to select the arrow tool.
1-800-LOGGERS 65 www.onsetcomp.com
Page 66
HOBOware User’s Guide
If you are currently using another tool and do not want to switch tools, press N on your keyboard to select each graph item (including hidden items, such as value axes for states or events) in sequence.
The selected item (if visible) is shaded or boxed. You can then right-click the selected item, double-click it, or press the Enter key on your keyboard to open the Properties window for that item.
To deselect, click an area within the axes that does not have series data. Click the View menu and choose Select None or press D.
Using the Crosshair Tool
Use the crosshair tool to zero in on a specific date and time in the plot and any data points associated with that date and time. To use the crosshair:
1. Click the Crosshair icon
2. Click a point on the graph to mark it.
3. Click another point to move the marker.
When you click on a graph, the nearest data point is selected. When series are very close together and the location you click is between two points, it is possible that the nearest point is not on the series you clicked.
You can also mark the point on the graph by clicking the corresponding cell in the Points table. If you are zoomed in and click a point in the Points table that is outside the zoom area, the plot will scroll to that area of the graph. To prevent scrolling in this situation, go to the Preferences, select Plotting and then Points Table & Details Pane. Deselect the "When selected value in table is out of plot range, drag series to that value.
The plot changes in several ways when the crosshair is in use. The Points table shifts to the row that contains the data point. Where the crosshair intersects a data point, a square surrounds the data point. The intersection points are also marked by small color-coded arrows on the left and right value axes.
If the legend is displayed next to the graph, the point values for each series are updated to reflect the crosshair location. Values are listed in the legend differently depending on whether the data is a logged sample, state, or event:
on the toolbar or press C.
Values that are not in parentheses are actual data points logged at the time selected by the crosshair.
Values in parentheses are estimated because there were no exact values for the series at the time
selected by the crosshair. Zoom in or move the crosshair to see actual values.
A value of "…" indicates that there is no series data during the time selected. This is seen most
frequently for events. If the time selection falls within an event series, but does not contain an event, parentheses surround the "…" value.
A value of "logged" indicates an internal logger event happened at the selected time.
The legend must expand in height to list the point values. If your application window is too small to accommodate the expanded height, the values will not be added to the legend. You can still refer to the Points table to find the values of the selected points.
To remove the crosshair from the graph, right-click the plot and select Remove Crosshair or choose remove Crosshair from the View menu.
Zooming, Panning, and Smart Scaling Plots
You can adjust the viewing area of the plot by zooming, panning, and smart scaling.
1-800-LOGGERS 66 www.onsetcomp.com

HOBOware User’s Guide
Zooming
There are two ways to zoom: either by using the zoom tool (or pressing Z) or by selecting Zoom In or Zoom
Out clicking the right-mouse button to zoom in or out. Use the Zoom In/Zoom Out icons to keep the plot centered as you zoom.
When zooming:
from the toolbar or the View menu. Use the zoom tool to zoom anywhere on the plot that you select,
Right-click to toggle between zoom in and zoom out.
Check the symbol inside the zoom tool to determine the direction you are zooming. A plus sign (+) or
arrows pointing outward will zoom in, while a minus sign (-) or arrows pointing in will zoom out.
Click an area on the graph inside the axes to zoom one level (a factor of two). Continue clicking to
zoom multiple levels.
Hold down the left mouse button in one location to zoom continuously. Release the mouse button to
stop zooming.
Hold down the left mouse button while drawing a rectangle around the area you wish to zoom in on,
then click inside the rectangle. The area inside the rectangle expands to fill the whole graph.
To constrain the zoom to horizontal or vertical zooming, place the cursor over the axis you want to
zoom and click the mouse button. Hold the mouse button down to continue to zoom. Or, press the X key while zooming to restrict motion horizontally and press the Y key while zooming to restrict motion vertically.
If you are currently working with the crosshair, arrow, or hand tool, you can click the Zoom In/Out
icons on the toolbar to quickly zoom into and out of the middle of the display without changing tools.
Zooming will not work on an axis that is locked. To unlock an axis, double-click the axis with the arrow
tool and deselect the Lock Axis Scaling and Tick Marks in the Axis Properties window.
Panning
Use the hand drag tool or press H to pan the graph, which is dragging the plot viewing area along the x- or y­axis. Panning is especially helpful when you are zoomed into a detailed plot and want to focus on a different area without zooming out. Click within the graph and hold down the left mouse button to pan a different section of the graph into view. The graph follows the movement of the mouse, and the axes are continuously updated in response to the movement. To stop dragging, release the left mouse button.
To limit dragging to horizontal or vertical panning, place the cursor over the axis you want to drag, hold down the mouse button, and drag in the direction you want the plot to move. Or, press the X key will dragging to restrict motion horizontally and press the Y key while dragging to restrict motion vertically. Similarly, click the axis associated with a series and hold down the left mouse button. Only the series connected with the axis will follow the movement of the mouse.
Use the hand tool to move different areas of the graph into view or adjust the position of one series so it can be viewed more easily. This is particularly useful when you are zoomed into the graph and want to see another section of the graph without zooming out and then zooming back in on the new location.
Panning will not work on an axis that is locked. To unlock an axis, double-click the axis with the arrow tool and deselect the Lock Axis Scaling and Tick Marks in the Axis Properties window.
Smart Scaling
When you first display a graph, the numerical bounds of the axes are on tick marks. After you have panned or zoomed, this may no longer be the case. Use smart scaling to correct that. With the hand drag, arrow, or crosshair
1-800-LOGGERS 67 www.onsetcomp.com

HOBOware User’s Guide
tool, right-click anywhere on the graph and select SmartScale Graph. This will automatically adjust the axes to end on tick marks.
Note: You can always return to the original plot view by clicking the View at Full Scale View menu.
from the toolbar or the
Copying Data Points and the Plot
To copy the data points from the Points Table to paste into other software:
1. Select the data you wish to copy in the Points Table.
2. Press Ctrl+C in Windows or Command-C in Macintosh to copy the data.
Windows: press Ctrl + C
Mac: press Command - C
3. Open any text editor, word processor, or spreadsheet software.
4. Press Ctrl+V in Windows or Command-V in Macintosh to paste the data into the other application. Fields are delimited by tabs, and records are separated by paragraph returns.
You can also copy the plot as a bitmap for pasting into other programs and documents. To copy the plot:
1. From the Edit menu, select Copy Graph to Clipboard.
2. Go to the other application and paste the plot.
Closing a Plot
To close a single plot, click the on the tab or toolbar, or choose Close from the File menu. On Macintosh, click the red button in the upper-left corner of the internal frame containing the plot when in Tabbed View. To close all open plots, select Close All from the File menu.
Important: Any changes you made to the plot are not saved when you close the datafile. You must save the plot as a project file to preserve the changes. Either select Save Project from the File menu before closing the plot or close the file and click Save when prompted. If you only want to save an image of the plot, you can paste a bitmap of the graph into another program and save it there.
Note: If you do not want HOBOware to prompt you to save the plot as a project file when you close it, open the Preferences. Select Warnings and then select General. Deselect the "Prompt me if there is any remaining unsaved data when closing plot or application" checkbox.
Viewing a Pie Chart
Pie charts are available in HOBOware Pro for plotted state series, such as those from the UX90 data loggers. This provides you with a graphical representation of the data for viewing, saving, and printing in addition to the default line graph. This is particularly useful for the UX90 Occupancy/Light Data Logger (UX90-005x/-006x) because it allows you to quickly compare when the:
Lights were on and the room was unoccupied
Lights were on and the room was unoccupied
Lights were off and the room was occupied
Lights were off and the room was unoccupied
1-800-LOGGERS 68 www.onsetcomp.com
Page 69
To view a pie chart:
1. Open a file from a logger with state series and plot the state series and derived series (as applicable) that you want to view in the pie chart. Note that a pie chart icon appears in the Plot Setup window if the file you are opening can be plotted in pie chart.
2. Click the Pie Chart button on the toolbar.
3. A pie chart is drawn based on the selected series. In this example, light & occupancy are plotted in the pie chart. The legend at the bottom of the chart indicates what series each piece of the pie represents. Percentages for each pie wedge are shown in the yellow boxes.
HOBOware User’s Guide
To change the series used to generate the pie chart, click the "Select a Series" drop-down
arrow and then click the Update Chart button.
To change the timeframe used to create the pie chart, change the Start and End Date/Time as
necessary and then click the Update Chart button.
To reset the pie chart to use the Start and End Date/Time for the current selected series, click
the Reset/Show at Full Scale
button.
To save the pie chart as an image (.png file), click the Save button.
To print the pie chart, click the Print button.
1-800-LOGGERS 69 www.onsetcomp.com
Page 70
4. When you are done viewing pie charts, click the Close button.
Notes:
The pie chart button on the toolbar will only be enabled when one or more state series is plotted. If
you have plotted data and the pie chart button is not enabled as expected, close the plot. Reopen the file and make sure you select the state series from the Plot Setup window. Note that if the sensor channels were configured as runtime instead of state, then pie charts will not be available.
If you merge datafiles, pie charts may not function properly if the time overlaps between merged
series. If you are having difficulty viewing a pie chart for a merged file, try returning to the original separate files to view the individual pie charts from each file.
If you are working with a plot that has two series, such as Light and Occupancy and you crop one of
those series, the time range for the pie chart data will be constrained to the shorter of the two series.
If you paste a new state series into the plot, it will also be available from the Select a Series pull-down
list. You will need to select the series to view it in a pie chart; it will not display automatically.

You can also use the Display preferences to set the default unit types and date/time format.
Setting Axis Properties
You can change the appearance of the time axis (x axis) and the value axis (y axis) on the plot. You can customize the axis name, change the location, bounds, tick marks, color, and more.
To change the axis properties:
1. Double-click the axis in the plot with the arrow tool, or select the axis and click the Properties icon
to open the Axis Properties window.
2. In the Name field, enter up to a 40-character name for the axis. The default name for a value axis is the unit type (for example, "°F" is the name for a temperature axis and "%" is the name for an RH axis). The time axis does not have a default name. To add "Time" as the default name for this axis, open Preferences. Select Plotting and then select Other Options. Enable the "Label the time axis" checkbox.
3. Change the location of the axis. The value axis can be located on the left or right while the time axis can be located at the top or bottom
4. By default, tick marks are auto-calculated. Numbers or values are listed next to major tick marks and minor tick marks are not numbered. To change the default tick marks, select Custom Tick Marks and then choose the values for Major and Minor tick marks as desired.
1-800-LOGGERS 72 www.onsetcomp.com
Page 73
5. Change the default bounds used on each axis. For the time axis, select the dates and times you want the axis to display. For the value axis, type the minimum and maximum value you want the axis to display.
6. You can also modify the appearance of the axis with these options:
Show Gridlines. This toggles whether gridlines are displayed in the background. Gridlines are
shown by default for the time axis, but not for the value axis.
Hide Axis. This controls whether the axis is displayed or temporarily hidden.
Lock Axis Scaling and Tick Marks. This controls whether the axis and associated tick marks
remain in their original position when zooming or navigating with the hand tool. Locking the axis and tick marks helps to avoid inadvertently zooming or navigating to an area on the graph without data.
Color. Black is the default color for the time axis. The color of the value axis matches the series
color by default. You can change the color for either axis as desired.
7. Click Apply to update the plot and keep the Axis Properties window open. Click Done to update the
plot and close the window.
Setting Series Properties
HOBOware User’s Guide
A series is the group of data points you selected to display in the plot. You can change the appearance of a series on the plot including the line style, point marker, alarm values, associated axes, and color.
To change series properties:
1. Double-click the series you wish to modify or select the series and click the Properties icon open the Series Properties window.
to
2. Change the default description. Type up to a 40-character name for the series. The series name will be
updated in the legend, series pane, and details pane to the new name you entered.
3. Change the default units. Enter a different unit type as needed. The unit type will be updated in the
legend, series pane, and details pane to the new unit type. Note that if you subsequently convert the units while viewing the plot, your custom unit type will no longer be displayed. For example, let's say you change the unit type for a temperature series from °F to "degrees." Then, while viewing the plot,
1-800-LOGGERS 73 www.onsetcomp.com
Page 74
HOBOware User’s Guide
you decide to convert the data points to Celsius. The unit type for the temperature series automatically changes to °C instead of the custom "degrees" unit that you had entered.
4. Adjust the appearance of the lines with the following options:
Connect Points. This controls whether the plotted data points in the series are connected with
a line.
Style. This changes the appearance of the line used to connect the points in a series.
Width. This changes the width of the line used to connect the points in a series.
Connect as Steps. This controls whether the lines between the points in a series are connected
as a curve or a step. When this option is selected, the line drawn between points keeps the value of the previous point until the next point in the series. Connecting as steps is useful when plotting state or event series.
5. Set High Alarm and/or Low Alarm thresholds. Enabling alarms will show lines on the plot for the series to indicate a visual threshold over or under which data may be falling (for example, if you want to quickly see how many points fall below 32 degrees). Alarms are available for sensor measurement series only, not for state or event series. Select the High Alarm checkbox and type a value relative to the series where you want the maximum (red) alarm line to appear. Select the Low Alarm checkbox and type a value relative to the series where you want the minimum (blue) alarm line to appear.
6. Select the Mark Points checkbox to add a marker for each data point in the series. To avoid cluttering the plot, this option is only enabled by default for series with event data or that have only one data point. If you enable Mark Points, you can change the shape of the marker and the point size.
7. You can also modify the following:
Time Axis. This allows you to create an additional time axis for this series. This is useful for
comparing data from two different time periods.
Value Axis. This changes the axis being used for the series. Choose one of the axes already in
view or select New Value Axis from the dropdown list to create your own.
Color. This changes the color used for the series.
8. Click Apply to update the plot and keep the Series Properties window open. Click Done to update the plot and close the window.

Selecting a Subset of the Plot (Subset Statistics Tool)
The Subset Statistics tool allows you to select a subset, or a range of data, of a graph, and display the maximum, minimum, average, and standard deviation for the measurements in that range (HOBOware Pro only).
To use the Subset Statistics tool:
1. Select the Subset Statistics tool
Statistics Tool icon
.
2. Draw the subset on the plot. With the left mouse button, click within the graph to define the start
time of the subset and drag to the right. Release the mouse button when you reach the end time of the subset.
The graph subset appears in the graph and the subset statistics pane appears beneath the Details pane as in the example below. Two black vertical indicators appear on the graph to show the range of the subset with date/time labels marking the start and end of the range. To move the vertical indicators and date/time labels, press the up or down arrow keys (make sure the Subset Statistics Tool is selected first).
from the toolbar. The mouse cursor will change to the Subset
A subset bar is added to the time axis. Double-click this bar to toggle between showing and hiding the vertical indicators and date/time labels. If the plot has one than more time axis, this bar is attached to the one that was created when you first displayed the plot. Click inside the subset bar to drag it to a different time axis.
To quickly adjust the start or end of the subset, click and drag the left or right end of the subset bar on the time axis (make sure the Subset Statistics Tool is selected first). You can also use the arrow keys to move the left boundary and Ctrl+arrow key (or Command-arrow key on Mac) to move the right boundary. Place the cursor in the middle of the subset bar and drag it to move the entire range left or right.
1-800-LOGGERS 77 www.onsetcomp.com
Page 78
To further refine the subset range:
HOBOware User’s Guide
1. Click the checkmark icon
in the Subset Statistics pane.
2. The two checkboxes are enabled by default. Deselect "Show subset statistics for time bounds below" if you want to remove the subset from the current time axis. Note that only one time axis can have a subset. If you enable subset statistics for one time axis when another time axis already has a subset, the other time axis's subset will be removed.
Deselect the "Show times, duration, & vertical indicators on graph" checkbox to toggle the display of subset indicators and labels on the plot. If you disable this option, the Subset Statistics pane and the shaded subset statistics bar on the time axis will still remain visible.
3. The easiest method to set a range for the subset is to indicate a fixed Start Date/Time or End Date/Time and then indicate the duration. Alternatively, you can enter both a Start Date/Time or End Date/Time without specifying a duration.
For example, to set a range beginning at 8:00 a.m. on 3/18/13 with a duration of 2 hours, set the Start Date to 3/18/13 and the Start Time to 8:00:00.000 AM. Select the Anchor Start Point checkbox and set the Duration to 2 hours as shown below.
1-800-LOGGERS 78 www.onsetcomp.com
Page 79
As another example, to set a range of 1 day ending at 10:00 PM on 3/18/13, set the End Date to 3/18/13 and the End Time to 10:00:00.000 PM. Select the Anchor End Point checkbox and set the Duration to 1 day.
To remove the subset and related elements:
Right-click the plot and select Remove Subset Stats,
From the View menu, select Remove Subset Stats, or

for barometric pressure and create a water level or sensor depth series. The BCA uses water pressure data from a HOBO U20 or U20L Water Level logger and additional information you provide.
Conductivity Assistant. Use the Conductivity Assistant to apply compensation to absolute
conductance data from a HOBO U24 Conductivity logger.
Dissolved Oxygen Assistant. Use the Dissolved Oxygen Assistant to generate a series adjusted for
salinity and a series for percent saturation based on data from a HOBO U26 Dissolved Oxygen logger. Also use this assistant to enter field calibration readings to compensate for fouling.
Grains Per Pound Assistant. Use the Grains Per Pound Assistant to calculate the absolute amount
of water in the air, based on temperature, humidity, dew point, and altitude. You can also create an altitude-corrected dew point series.
Growing Degree Days Assistant. Use the Growing Degree Days Assistant to calculate growing
degree days based on temperature data spanning at least one full calendar day (midnight to midnight). Growing degree days are used for agricultural and turf management applications, such as estimating harvest time or pest growth.
kWh Assistant. Use the kWh Assistant to convert logged pulse data from a WattNode, Veris, or other
energy transducer to kWh, average kW, and energy cost. The kWh Assistant can be run during Plot Setup or at Launch.
Default Settings
The parameters last entered into any given Data Assistant will be the default used the next time the Data Assistant is run, unless it is being used to edit existing series. If you run a Data Assistant at Plot Setup time and then later you run it from the Launch Logger window, the default values are the value you entered at Plot Setup time.

To create a water level or sensor depth series:
1-800-LOGGERS 89 www.onsetcomp.com
Page 90
HOBOware User’s Guide
1. Read out a logger or open a datafile that contains water pressure data from a U20 or U20L Water Level Logger.
2. From the Plot Setup window, select Barometric Compensation Assistant and click Process.
3. Provide Fluid Density information by choosing a water type (fresh, salt, or brackish), entering a specific constant value, or using the temperature series (if logged) to use temperature-compensated density assuming fresh water.
4. To enter a reference water level, check the Use a Reference Water Level box, enter the water level, and indicate whether it is in feet or meters.
Enter the water level as a positive number if it is measured upward from a reference point
below the water's surface, such as the water's height above sea level. This illustration shows an example of when to enter the water level as a positive number.
1-800-LOGGERS 90 www.onsetcomp.com
Page 91
HOBOware User’s Guide
Enter the water level as a negative number if it is measured downward from a reference point
above the water's surface, such as a well cap. This illustration shows an example of when to enter the water level as a negative number.
Then, from the drop-down, select the logged time and value that is closest to the time when you measured the water level.
When selecting a logged value and time to link to the reference level, make sure the logger
readings have stabilized. When a logger is first deployed in water, it takes some time for its temperature to reach equilibrium. You will get the best accuracy if you link your reference reading to a stabilized logger reading.
When using a reference water level, the resulting series data will contain water level values
relative to this reference level. If you do not use a reference water level, the resulting series data will contain values for absolute sensor depth.
5. You can either use a barometric data file from another source, or enter a fixed barometric pressure. For the most accurate water level results, use a reference water level and a barometric data file. The barometric data can come from another HOBO U20 or U20L or U20L Water Level Logger in air; a HOBO Weather Station, HOBO Micro Station, HOBO U30, or HOBO Energy Logger; or a text file from another source.
To use another file to provide barometric information, click the Use Barometric Datafile button
and enter (or browse to) the name of a .hobo, .hsec, .dtf, .dsec, .csv, or .txt file that contains a barometric pressure series from an overlapping time period. You will have the option to display this series on the plot. Important: Text files must follow specific requirements as described in Import Text Files Requirements.
To use a constant pressure value, click the Use Constant Barometric Pressure button. Enter the
constant value and indicate whether it is in psi or kPa. (You cannot use a constant pressure value in combination with a reference water level.)
6. Keep the default Resultant Series Name, or enter a new one. You may also enter User Notes concerning the series you are creating.
Note: Your settings are retained, so you do not need to re-select your density and barometric file each time you use the Barometric Compensation Assistant as long as they still apply to the new water level data set.
7. Click Create New Series. The new series is listed and selected in the Plot Setup window. You can click
Process on the Plot Setup window again to create another series using different barometric compensation parameters.

Starting and Ending Value: This method calibrates your data and adjusts for sensor drift or
fouling. This assumes there is a linear change in calibration adjustment required.
Starting value only: All readings are adjusted up or down by a fixed percentage of the reading
based on this calibration point.
Ending Value Only: The factory calibration value is used as the starting point. This assumes
there is a linear change in calibration adjustment required.
Note: You cannot use a zero-point calibration solution for starting and ending values. The first data point cannot be used as the ending value; consider using that as the starting value instead.
6. Select the Only Report Data Between the Selected Points checkbox if you want readings from before or after the calibration points to be removed from the resulting series.
7. In the Series Name field, keep the default name or type a new one.
8. Type any User Notes concerning the series you are creating (optional).
9. Click the Create New Series button.
10. The Plot Setup dialog lists a series called Specific Conductance (or the name you entered for Series Name). The default units are microSiemens/cm (µS/cm). You can change the units to milliSiemens/cm (mS/cm) if desired. The default units for salinity are ppt (parts per thousand) and this cannot be changed.

11. Click the Plot button to plot the data. The Details Pane will show the series selected in the Plot Setup:
After the plot is displayed, you may apply minimum, maximum, and average filters to the scaled series as you would for any sensor data series in HOBOware Pro.
12. Save this plot as a Project to preserve this processed data.
Calibration
It is important to take temperature and conductivity calibration readings with a portable conductivity meter at both the beginning (launchtime) and end of a deployment (readout) because these readings are necessary for data calibration and to compensate for any measurement drift during deployment. The temperature and conductivity calibration readings should be the actual conductivity values (not in specific conductance at 25°C), and should be recorded in a notebook with the time and location of the reading. See the logger manual for details on different methods of obtaining water samples to record these values.
1. Once the logger is deployed and logging, record in a notebook the temperature and actual conductivity meter readings along with the date and time which will be entered into the Conductivity Assistance to correct the field data.
2. Before you remove the logger and read out its data, take another temperature and conductivity reading with the meter and record the exact date and time.
3. Enter these values under the "Use measured points for calibration" option in the Conductivity Assistant.
Notes:
Whenever a logger is removed for downloading data, clean the sensor window using a cotton swab
with a mild detergent and rinse.
If the water in the field is not accessible to the conductivity meter sensor, such as in a deep well, a
bailer can be used to fetch a water sample for testing. See the logger manual for more details.

Dissolved Oxygen Assistant
The Dissolved Oxygen Assistant corrects for measurement drift from fouling and provides salinity-adjusted DO concentration as well as percent saturation data.
1. Read out a U26 series logger or open a datafile from a U26 logger.
2. From the Plot Setup window, select the Dissolved Oxygen Assistant and click the Process button.
3. With the Dissolved Oxygen Data Assistant, you can adjust the data for salinity (step 4), enter barometric pressure information for percent saturation calculation (step 5), select the resultant series you wish to generate (step 6), and enter field calibration data (step 7).
4.
Adjust for salinity. If you deployed the logger in saltwater, you must adjust for salinity to get either
a DO concentration or percent saturation. To do this, select the "Adjust for Salinity" checkbox (you will also need to select the checkboxes under Resultant Series Information for the series you would like). Select whether the series should be adjusted based on salinity or specific conductance.
If you chose salinity: Select "Salinity value" if you have a specific value from a conductivity
meter reading or other source; type the value in ppt as shown below. This works well if the salinity is constant during the deployment. If the salinity changes during the deployment, select "Salinity datafile" to use a data file from a U24 conductivity logger or a text file. Click the Choose button and select the file. (See the Important note for more details about using files.)
If you chose specific conductance: Select "Sp. cond. value" if you have a specific conductance
value from a meter reading or other source; type the value in either µS/cm or mS/cm as shown below. This works well if the specific conductance is constant during the deployment. If it is not constant, select "Specific conductance datafile" to use a data file from a U24 conductivity

D. Click the "Use default BoxCar Pro export settings" button and click OK. This will ensure the text
file you create is the proper format for the Dissolved Oxygen Assistant.
E. From the File menu, select Open Datafile and select the U24 .hobo file.
F. In the Plot Setup window, select the Conductivity Assistant and click Process.
G. In the Conductivity Assistant, create a calibrated specific conductance or salinity data series.
H. Back in the Plot Setup window, select the specific conductance or salinity series only. Click
None under Select Internal Events to Plot so that no events are plotted.
I. Click the Plot button.
J. From the File menu, select Export Table Data. Choose "Export to single file" if prompted.
K. To use the calibrated conductivity file, open the DO file again. In the Plot Setup window, select
the Dissolved Oxygen Assistant and click Process. Select the text file you just created in the previous step for the salinity or specific conductance datafile. This file will be used to generate the series adjusted for salinity.
Use barometric pressure (for percent saturation). Check the "Use barometric pressure (for
5. percent saturation)" box if you want to generate a DO percent saturation series (you will also need to select the DO Percent Sat. checkbox under Resultant Series Information). For the best accuracy, use a data file from a HOBO Water Level logger deployed in the air or a nearby weather station. Select "Barometric Datafile" and click the Choose button to select the .hobo or .txt file.
Important: If you
are using a .txt file from a non-HOBO device, it must follow specific requirements as described in Import Text File Requirements.
If you do not have a barometric pressure file, then select "Barometric data value" and type in the average barometric pressure during your deployment in one of the five available units.
If the barometric pressure readings are from barometric data that has been adjusted to sea level readings (such as those taken from a National Weather Service weather station), then you must also select the "For sea level barometric pressures, enter elevation" checkbox and type the elevation where the logger was deployed in either meters or feet. Absolute pressure values, such as those obtained from a HOBO Water Level logger, do not need to be adjusted for elevation.

6.
Resultant Series Information. Make sure the series you want to plot are selected in the Resultant
Series Information pane. To generate a series for adjusted DO concentration, check the "DO Adj Conc." box. To generate a series for percent saturation, check the "DO Percent Sat." box. The default series names display automatically to the right of the selected series. Edit those series names as needed. You can also type up to 250 characters of optional user notes.
7.
Perform Field Calibration. Use field calibration to compensate for measurement drift due to fouling
or if the logger was not lab calibrated. (Lab calibration typically remains accurate for the full 6-month life of the sensor cap if there is no fouling.) Check the "Perform field calibration" checkbox and select the type of field calibration: either "Using Dissolved Oxygen Meter or Dissolved Oxygen Titration" or "Using 100% Water-Saturated Air."
For calibration using a dissolved oxygen meter or titration: Select the "Starting calibration
point" checkbox and select the date/time of the calibration reading. View the logged data values shown in the drop-down box to be sure that the logger readings have stabilized. It is more important that you use a good stabilized logger reading than exactly matching the times. Type in the Meter/Titration DO Measurement in mg/L taken at that date/time. If using an ending calibration reading, or, if desired, select the "Ending calibration point" checkbox and select the date/time of that calibration reading. Make sure the logger reading you use for calibration is one from when the logger was in the water, keeping in mind that the logger time may be slightly different from the time used for your field readings. You can usually see the data points that were recorded when the logger was out of the water. Type in the Meter/Titration DO Measurement in mg/L for this ending calibration point.

Note: If only an “Ending calibration point” is entered (“Starting calibration point” not checked), then the assistant will use the logger calibration for the starting calibration. This assumes you are starting with an accurately calibrated logger and saves you from having to do your own starting point calibration. However, if you select a “Starting calibration point” and no “Ending calibration point,” the series will be adjusted for the one calibration point. This may be accurate enough for applications where there is no significant fouling during the deployment time.
For calibration using 100% water-saturated air: Select the "Starting calibration point"
checkbox and the "Ending calibration point" checkbox and select the date/time for the first calibration reading. View the values shown in the drop-down list to be sure the readings are stable at this calibration point (using a calibration point from when the logger is in air or has not reached temperature equilibrium will result in incorrect calibration). Select the source of the barometric pressure readings. From the Barometric Pressure drop-down list, select "from the left" to use the barometric pressure data file already entered in the assistant or select "entered here" to enter a specific barometric pressure value in one of five available units. If you are using an ending calibration reading, select the “Ending calibration point” checkbox and select the date/time of that calibration reading following the same guidelines as you did for the starting calibration point. For the ending point, enter the barometric pressure information (select “from the left” or “entered here” as described above).

Check the "Only report data between selected points" if you want the new series to only include data between the selected calibration points. Leave this option unchecked to include all data.
8. Click the Create New Series button when finished entering information in the data assistant.
9. Depending on which series you selected to add, the Plot Setup dialog lists two news series: DO Adj
Conc and DO Percent Sat (or the names you entered for Series Names). The default units for the DO Adj Conc series are mg/L. You can change the units to ppm if desired.
10. Click the Plot button to plot the data. After the plot is displayed, you may apply minimum, maximum,
and average filters to the scaled series as you would for any sensor data series in HOBOware Pro.
11. Save this data and plot setup as a Project to preserve the new series you created for future use.
