5. Operation

5.1. Operating modes

Four different operating modes can be selected for the data logger. The selected operating mode (selection) is indicated in the bottom left-hand corner of the display with S1, S2, S3 or S4. Switching between the various operating modes is effected via the operating mode button.

To select the desired operating mode, press and hold down the operating mode button with the aid of a blunt object, such as a ballpoint pen, until the desired operating mode (S1, S2, S3, S4) is indicated in the bottom left-hand corner of the display.

The four operating modes:

Operating mode 1 (S1)

The data logger is switched off. OFF appears in the upper line.

Operating mode 2 (S2)

The data logger is switched on; it determines the measured values of the individual measurement channels and displays them, as described in chapter 5.4. The logging mode is

not activated in this operating mode; the displayed values are not stored in the memory. The display indicator for the storage of the measured values therefore displays STOP (no recording).

Operating mode 3 (S3)

The data logger is switched on; it determines

the measured values of the individual meas-

urement channels and displays them, as de-

scribed in chapter 5.4. The logging mode is

activated in this operating mode; the displayed values are stored in the memory. The display indicator for the storage of the measured values therefore displays REC (recording of the measured values).

Operating mode 4 (S4)

The data logger is switched on; it determines

the measured values of the individual meas-

urement channels but does

not displa

y them. The logging mode is activated in this operating mode; the displayed values are stored in

the memory. The display indicator for the storage of the measured values therefore displays REC (recording of the measured values).

5.2. Switching on and off

The data logger is switched on and off via the operating mode button (see chapter

5.1). The equipment is delivered as standard in operating mode S1 (switched off).

Switching on

Press and hold down the operating mode button of the switched-off data logger with the aid of a blunt object, such as a ballpoint pen, until the desired operating mode (S2, S3, S4) is displayed. The device is now operating.

Switching off

Press and hold down the operating mode button of the switched-on data logger with the aid of a blunt object, such as a ballpoint pen, until operating mode S1 and OFF are displayed. The device is now switched off.

5.3. Connecting external sensors:

The connection of external sensors is not possible for this model.

5.4. Displaying the measured values

Two different measured values are displayed simultaneously.

5.5. Data recording options (logging)

When operating mode S3 or S4 is selected, the data logger is in logging mode and the measured values determined are stored in the device. The specifications for the type, duration and scope of the data recording in logging mode can be individually set via the software.

The following list of the various options serves only as a quick overview; more detailed information on this subject may be found in the software handbook.

Selection possibilities for the logging mode:

The measuring instrument records the measured data continuously. Two possibilities for the organisation of the memory are available for selection:

Start-stop mode

In start-stop mode, the measured data for each channel is recorded until the memory capacity of 60,000 values per channel is reached. Recording is then ended automatically.

Ring mode

Alternatively, ring recording mode may be selected in place of start-stop mode. In this case, the recording does not stop when the memory capacity has been reached, but continues indefinitely. To this end, the respective oldest values are continuously overwritten by the newest measured values.

Further adjustable parameters for the logging mode:

Sampling rates

The measured value to be stored during sampling can be selected via the software for each logging mode. The following measured values can be selected in any combination as desired: average value, minimum value and maximum value.

Additionally, the sampling rate for the sensor and the storage rate for recording the measured values can also be set. Both rates can be set from 1 to 1440 minutes.

Preset operating mode

Besides the possibility of starting the recording of measured values immediately, the data logger can also be used in the so-called preset operating mode. The starting date and time for the measurement period are set and the recording of the measured values starts at this time.

If preset operating mode has been selected, the starting flag symbol is displayed in the lower display line and the starting date and time for data recording will be displayed alternately in the date/time display.

When the preset starting time is reached, the starting flag display disappears, the real time clock is displayed, the data logger switches automatically from the previous operating mode (S1, S2, S3) to the logging mode of operating mode S4 and data recording begins. It is therefore not neces-

sary to switch on the logger in preset operating mode.

Even if the data logger had already been previously switched on, in preset operating mode it records exclusively the measured data for the defined period, but not the measured data from the time of switching on.

Alarm function

A separate alarm function for each measurement channel can be configured via the measuring instrument administration. A value corridor is specified, the so-called ‘good’ range, outside of which an alarm is triggered, via the definition of an upper and lower alarm limit value.

If an alarm is triggered on one of the available measurement channels, a continuously flashing alarm symbol appears alongside the measured value for this channel for as long as the measured value lies outside the ‘good’ range.

If the measured values re-enters the defined value corridor, i.e. the ‘good’ range, the alarm no longer flashes, but is displayed statically. This is intended to indicate that an alarm event has taken place. If the measured value once again moves outside the ‘good’ range, the alarm symbol flashes again.

The alarm display is extinguished by reading out the measured value memory.

Additionally, a hysteresis can be set, by which value the measured value must re-enter the valid range in order to switch off the alarm.

Further information on alarm hysteresis and its practical use can be found in the chapter “Tips and tricks”.

Note: The visual illustration of the alarm function on the display is only available in operating modes S2 and S3! The storage of alarm events in logging mode is, however, independent of the select

ed type of display of the measured values, i.e. the alarm events are recorded even in operating mode S4 with the display deactivated.

6. Notes on maintenance and operation

Positioning for mobile use

The data logger can be positioned as required for the mobile recording of measured

values. Please observe the permitted ambient conditions for operation (see

technical details) Due to its compact dimensions, the data logger can also be placed

out of sight for inconspicuous use.

Wall mounting

The data logger can also be mounted on a wall for the stationary recording of data.

A fixing kit for wall mounting is included in the package. Only the holding plate need

be mounted on the wall to install the data logger. The data logger can then be slid

onto the holding plate by means of the guide rail at the rear.

Change of location

In particular when moving from a cold to a warm environment, for example, when bring-

ing the device into a warm room after overnight storage in a car, water may con-

dense on the circuit board, depending on the relative humidity of the air in the room.

This physical effect, which cannot be prevented by structural means for any meas-

uring instrument, leads to false measurement values. In such cases, please wait

about 5 minutes until the measuring instrument has ‘acclimatised’ itself before com-

mencing with measurements.

Battery replacement

If BATT appears in the upper line of the display, the battery must be replaced.

In order to replace the battery, first separate the display module from the sensor module. Carefully lift the connecting tab at the rear of the data logger with the aid of a suitable tool, such as a screwdriver.

The sensor module can now be detached from the display module.

Loosen the four screws at the rear of the display module with a suitable screwdriver. Place the display module on a flat surface with the display facing upwards and carefully lift up the upper part of the plastic cover.

Please be sure to observe the correct polarity when inserting the battery and read the safety instructions on the battery. Only use batteries which comply with the technical data.

Other types of battery are not permitted and can cause faulty operation. Do not use rechargeable batteries!

Finally, screw the upper and lower parts of the casing together again, fit the sensor module onto the guide rail of the display module and carefully push the two modules together until they latch.

Operating manual THI/USB

A - 06

The battery should be replaced once per year. Frequent transfer of data to the PC reduces the battery lifetime.

Do not throw the batteries into the domestic waste, into a fire or water, but dispose of them correctly in accordance with applicable legal regulations.

“Set Clock” display

So that the clock setting is retained when changing the battery, it is recommended to set the device to operating mode S1 (see 5.1, Operating modes). The power consumption is very low in this operating mode and the clock setting will be retained if the battery is replaced quickly.

If the time setting is deleted (e.g. in case of a longer power interruption) “SEt CLOC” appears in the display (note: due to the 4-digit seven-segment display, the word “clock” cannot be fully displayed).

This indicates that the date and time should be set, otherwise the clock will start with the default value (e.g. 1/12/2005). The “Set clock” display remains visible until the time has been synchronised via the SmartGraph software. No measured values will be displayed until the clock has been set.

Care

Clean the device if necessary with a moist, soft, lint-free cloth. Take care that no moisture enters the casing. Do not use sprays, solvents, cleaning agents containing alcohol or scouring agents; use only clean water to moisten the cloth.

7. Tips and tricks

Use of alarm hysteresis

If the alarm function without hysteresis is used, an alarm will be triggered and recorded each time the specified limit value is exceeded. If your limit values are very tightly selected, this leads to a very frequent occurrence of alarm situations. For example, if a room temperature of 24 °C is entered as the upper alarm limit value and a room temperature of 10 °C is entered as the lower alarm limit value and the room temperature settles permanently in the range between 23.5 and 25 °C during the measurement period, the result will be that numerous individual alarm signals will be generated and recorded during the entire measurement period. In order to avoid this, an alarm hysteresis can be defined. With this setting, you can define a value by which the measurement value must re-enter the valid value corridor in order to switch off the alarm. With a set value for the alarm hysteresis of 1 °C, the alarm in the above example would only be triggered once when 24 °C was exceeded and would only be switched off again when the value fell below 23 °C.

Battery replacement and lifetime

So that your measuring instrument is always ready for use, the battery should be replaced once per year. Frequent reading out of the measured data reduces the battery lifetime.

Measurement intervals and recording duration

The type of measured values to be recorded and the respective storage rates should be adapted to the purpose of use.

If you are intending to create particularly detailed documentation and wish to use all the software evaluation options, you can simultaneously record the average, minimum and maximum values for each measurement channel.

Given a specified storage rate of 10 minutes, a maximum recording duration of around 183 days would be possible in this case. For recording at shorter intervals, the storage rate can be reduced to a value of one minute. However, this also reduces the maximum recording duration.

If the main object of your measurement is long-term documentation, you can just record one value, for example, the average value. At a storage rate of 10 minutes, the memory capacity for this configuration allows a recording duration of 416 days!

1 Introduction to SmartGraph

1.1 Manage, Configure

SmartGraph enables the flexible management of several data logger devices by means of identifiers. Devices can be added at any time. A unique description can be assigned to every device.

The measurement data is archived in files organized on a “calendar week” basis, stored in a separate folder (within the folder where SmartGraph was installed) for each device, named DlXXX, where XXX is a unique number assigned to each device.

Access to the data stored for each device is provided via the name of the device. A device can be selected via the File Menu item “selected device” or via the device list box in the toolbar.

For protection against data loss, e.g. because of a hard disk error, it is recommended to back up the data files (all DLXXX folders in the installation folder of SmartGraph) on a regular basis.

: The table is printed with the data of the selected day. This can also be done via the button

in the tools panel and via the menu item file -> print -> print table.

1.2.3 Auto Monitor

Data for every device is displayed on one or more monitor pages (depending on the auto monitor settings for the device) within the “auto monitor”.

Select the device: The device for which data is displayed can be selected in two ways:

- select the device from the selection list in the toolbar

- select the device from the menu item file - selected device

The name and identifier of the selected device are displayed in the caption of the main window.

Auto Monitor options: Diagrams and table for the selected device are displayed based on the options set for the auto monitor for this device. The settings can be viewed and changed selecting menu item options - auto monitor:

- Maximum number of curves per diagram: a single diagram can be limited. Valid values are between 1 and 10. If more channels than the maximum for one diagram are present in a data source, an additional diagram is displayed.

- Maximum number of diagrams per monitor page: data source determine how many diagrams are necessary for presentation. If more diagrams are needed than the maximum number allowed per monitor page, additional monitor pages are displayed, and can be selected by the tab on the bottom of the window.

- Use both axes in diagrams: and right Y-axis if necessary, so that channels with data in two different units can be displayed. If the option is deactivated, only the left Y-axis is used.

- Place table on separate monitor: separate monitor page without diagrams. Otherwise diagrams and table are arranged together on one (the first) monitor page.

- Use as default for new devices: monitor will be used as default values for new devices that are added later to SmartGraph.

- Apply to all devices: page/device will be applied to all configured devices.

After the settings have been changed, diagrams and table will be formatted for the selected device according to the new settings.

The labels of the monitor pages are created from the device name and a serial number and cannot be changed by the user.

1.2.4 Monitor page for Tables and Diagrams

The monitor page is divided into two parts (if a table is present on the page). On the left side up to 9 diagrams are presented, on the right side a table. The border between the two sides can be moved using the mouse. The diagrams are arranged on the left side so that the space is filled as completely as possible. The arrangement of diagrams can be horizontal or vertical (see menu item View>Monitor).

Selection: Whenever a diagram or table is selected, various menu items and buttons like the “Print” button, are related to the selected object. The selected object (diagram or table) is marked with a blue border. An object can be selected by clicking with the mouse on the object. The next object can be selected by using the tab key.

Full Screen/Normal Screen: Each object (diagram or table) can be expanded to full screen size. The diagram or table then fills the entire monitor page. Switching to full screen and back to normal screen size can be done in 4 ways:

The menu items always relate to the selected object.

hide/show object: Each object (table or diagram) can be hidden, i.e. it disappears from the screen, but is not lost and can be shown again. The remaining objects on the monitor page are re-arranged.

Hiding an object can be done via:

The menu items always relate to the selected object.

Showing an object that has been hidden can be done via the context menu of the monitor page or the menu items in the “monitor” menu of the “Edit” menu. The object to be shown is selected form a list of hidden objects in a dialog box that pops up, and the position of the object in reference to the other visible objects can be specified.

Note: The mechanism can be used to change the sequence of the objects on a monitor page by hiding an object and showing the object at a different position.

Monitor page context menu: All functions that concern the monitor page are found on the context menu for the monitor page. This appears when the right mouse button is activated and the mouse is positioned over the tab panel of the Monitor or over the border between the diagrams and the table. The menu items also appear on the “edit -> monitor” menu (maximize/minimize object, hide/show object) or in the “view->monitor” menu (arrange diagrams horizontally/vertically)

1.3 Measurement device

1.3.1 read data

The content of the data logger/device that is connected to the PC via the serial interface is read and

stored. This function can be started by selecting menu item “device -> read data” or by clicking the button on the toolbar.

Requirement: The correct communication port must be configured. The communication port can be configured via menu item “device->communication”.

Messages: The date and time from where data is to be read from the device memory can be specified here. Default is the date and time of the last read out of the device memory. With the "read complete memory" option all data stored in the device will be read.

While the data is read from the device the message "transmission of data" is shown with an indication of the progress of the transmission (percentage reading).

If the communication port has not been set up correctly, a message “interface already open” may be displayed indicating the configured interface is already in use, e.g. the mouse could be connected to that port, or a message “device does not respond” may be displayed if no device is attached to the configured port. Please check the configured communication port if such an error message is displayed.

1.3.2 recorder

With the recorder function measurement data from the attached device is read in intervals. Unlike the data read by “read data”, the data read via the recorder function is not obtained from the device memory, but the measured values are read directly.

While the recorder is active, the connection to the attached device is permanently open.

Note : using the recorder function reduces battery life !

The recorder is started or stopped via the menu item 'device - recorder - start/stop recorder' or via the corresponding button

the status bar.

In recording mode, the following menu items under menu “device” are disabled:

- communication

- read configuration

- read data

- clear memory

- synchronize clock

The device internal clock is synchronized to the PC clock during the recording process.

The following actions stop the recording mode:

- changing device or channel settings ("configure devices")

- "delete device"

The time interval for data collection in recording mode is determined from the device’s “sample interval” setting.

If “auto scroll” is checked (menu device-> recorder or toolbar button device is displayed on the auto monitor page(s) for the device, and diagrams are scrolled to show the new data.

) new data read from the

When the recorder function is active, the time range for neither the diagrams (curves) or nor the table can be changed, and the selected device cannot be changed either.

1.3.3 clear memory

This function clears the memory of the attached device, i.e. the data stored in the device is deleted.

1.3.4 read configuration

The configuration of the connected device is read.

If no corresponding auto monitor page for the attached device has yet been set up, it is created. SmartGraph offers to switch to the appropriate auto monitor page for the device.

1.3.5 synchronize clock

The clock of the connected device is synchronized to the PC clock.

1.4 Display and analyze data

Measurement data can be displayed in diagrams covering time ranges from 10 seconds to 1 year.

To navigate within the time range of the diagrams use the buttons on the navigation toolbar on the

upper left under the main menu:

from the toolbar.

1.6 Organization of measurement data

The measurement data for each device is kept in a different folder within the SmartGraph installation folder. The data folders are named “DLxxx”, where xxx is the unique number assigned to each device by SmartGraph.

The measurement data is saved in files on a “calendar week” basis (i.e. one file per week) named "KWjjnn.sgr", where “jj” stands for the year and nn stands for the week number.

When a device is deleted the subdirectory DLxxx for the data of this device is renamed to DLxxxBAK. The files are not deleted. If a device has been inadvertently deleted, the procedure can be reversed as follows: quit SmartGraph and rename the folder DLxxxBAK to the DLxxx (e.g. using the File Manager). The next time SmartGraph is started the data for the device will be displayed again.

1.7 Upgrade to Extended Functions

In the professional edition of SmartGraph the following functions are available:

- Beside the standard measurement units (e.g. temperature in °C and humidity in %RH) other units (e.g. temperature in °F or dew point temperature, etc.) can be assigned to the channels/sensors of a device.

- Measurement data can be exported to text files (with several options for formatting).

- Extended functions for printing of diagrams are available (e.g. print all diagrams of a device, print all/selected diagrams of all/selected devices, print up to 4 diagrams on a single page).

Unlocking via key-code The upgrade to the professional version is done by aquiring a key code.

To do this, select the menu item options -> upgrade -> order. Fill out the fields in the dialog box "offer/order for unlock code". Select print to print out the order form. Fax the order to the given fax number / your distributor and you will shortly receive the Key-Code for the requested version.

If you are in agreement with the License conditions select the menu item options -> upgrade -> unlocking. Enter the key-code. The additional functions can now be used.

If the number of managed devices does exceed the number matching the professional version you have orderer, the additional functions are deactivated.

Test-Upgrade

Upgrade to professional or pharma version for testing - limited to 4 weeks.

logging mode:

The logging mode parameters for the device can be configured here.

- storing mode:

- sorting of:

- Sample interval : time difference between samples (times when measurement values are read

- Storage interval : time interval for data logging

preselection: When preselection is enabled data logging only occurs at the preselected time. The selected date/time must be set to a time in the future.

Note for devices of the DL-series: preselection does work for devices of the DL-series in start/stop and ring mode. For the DL 100M the device must be switched to mode S3 or S4 in order to activate preselection. A flag symbol in the display of the devices indicates that preselection is enabled. A clock symbol in the display indicates that preselection was activated (i.e. data is recorded). Other devices of the DL-series, i.e. all two- and four-channel devices with and without display, need to be switched on in order for preselection to work! Attention: For the DL 100M the symbol for enabled preselection is displayed even if the device is in mode S1 or S2 – but in those modes no data is recorded by the device!

sensors: The sensors attached to the two logger channels are displayed here. Settings: Using the buttons the edit dialog for the corresponding channel can be accessed (see edit channel).

Depending on the sensor circuit board installed in the device the following measurement units are available: Temperature in °C or °F, relative humidity in %RH, absolute humidity in g/m³, dew point in °C or °F

Not all measurement unit configurations are possible. The following limitations apply:

- With the internal sensor circuit board and the external circuit board with one probe the measurement units in the two channels must be different.

- With the external sensor circuit board with two probes the measurement units in the two channels must originate from different probes.

When the measurement unit for a channel for which data has already been stored by Smartgraph is changed, a new channel for the new unit is created.

The old data stored with the old unit setting can still be viewed. The device appears in SmartGraph now with more than two channels. The channel with the old unit settings no longer corresponds to any physical device channel. Accordingly, some parameters for this now “virtual” channel cannot be modified
