2.1 Using an I/R dongle with Log

Some Hart Scientific thermometer readouts, such as the 1522, have a built-in I/R port that can be used to communicate with a computer. I/R ports have many advantages over standard RS-232 ports which include increased data transfer rate, greater flexibility and ease of use.

Hart thermometer readoutss with an I/R port use a proprietary protocol for communication. Because of this proprietary protocol, LogWa re is not able to use I/R ports that are built into a computer. Instead, LogWar e requires the use of an I/R dongle (Figure 8) which can be connected to a standard RS-232 port. No special software or drivers are required to use the dongle. All necessary

Ware

Page 19

9934 LogWare

User’s Guide

communication protocols and drivers are built into LogWa re . To purchase an I/R dongle (model 2374), contact technical support.

Figure 8 Model 2374 Infrared Dongle

LogWare provides support for communicating over an I/R port with these thermometers. However, the support is limited to the following features:

• Downloading logged data from memory

• Checking log status

•

Writing labels associated with logged data

LogWar e does not support using the I/R port for real-time log sessions.

To use an I/R dongle with LogWar e, follow these steps.

1. Locate a 9-pin or 25-pin COM (RS-232) port on the computer. Connect the I/R dongle to the port. If the COM port is a 25-pin port, use a 9-25 pin adapter to connect the dongle.

2. In the Download menu, select either the Download Logged Data option or the Log Status option. Or, in the Tools menu, select the Write labels option. The Select Model dialog is displayed (see Section 8.5).

3. Select the thermometer model to use. Then select the COM port to which the I/R dongle is connected.

Note: In the COM port drop down list, ports with the symbol rep

resent built-in I/R ports and cannot be used!!

Page 20

Opening a configuration file automatically on start-up

4. Next, check the Use I/R Dongle check box. When this box is checked, the Baud Rate setting is ignored since the thermometers are fixed at 115,200 baud when using the I/R port.

5. To ensure the computer can communicate with the thermometer using the I/R port, place the I/R window of the thermometer in close proximity to the I/R dongle and make sure the path between the two is not ob structed (see the thermometer’s User Guide for details on the proximity requirements). Click the Test Communication button. If LogWa re suc ceeds in communicating with the thermometer a success message is dis played. Otherwise, a failure message is displayed. In case of failure, check the following:

The dongle is connected to the selected COM port

•

The thermometer is powered up and operating

•

The dongle is in range of the I/R port on the thermometer

•

The path between the thermometer and dongle is not obstructed

•

Shut the thermometer’s power off, then back on again

•

When communication succeeds, click the OK button to proceed to the appropriate dialog.

2 How to...

2.2 Opening a configuration file automatically on start-up

LogWare was designed to be flexible with the thermometers that it can use and the features it supports. However, most users of LogWar e will probably always use the same thermometer, scale, communication settings, log interval and channel and alarm settings to do all or most of their logging.

For this reason, LogWar e allows real-time log session settings to be saved to a configuration file. Opening the configuration file restores the settings eliminat ing the need to manually enter most of the information for a new log session.

Configuration files save the following information about a real-time log session:

•

Thermometer model, serial number and readings scale

•

Communications COM port and baud rate

•

Log interval and End Log settings

•

Channel trace color and filename

•

Alarm and statistics settings

The delayed start date and time information is not saved in the configuration file. For more information on configuration files, please read Configuration Files.

Page 21

9934 LogWare

User’s Guide

In addition to allowing configuration files to be saved and opened, LogWa re also allows one configuration file to be opened automatically every time LogWare runs. This configuration file can be specified in one of two ways:

From the Defaults dialog (see Section 3.4.1)

•

From the Log Session Settings dialog (see Section 4.1)

•

Opening configuration file automatically using the Defaults dialog:

Select the Defaults option from the File menu (see Section 3.4.1).

•

Select the General tab.

•

Check the Show Log Session Settings dialog on start-up check box.

•

Check the Load default configuration file automatically check box.

•

Click the “…” (Browse) button to select the configuration file to open or

•

type the path and filename in the Default configuration file box.

Click the OK button to save the changes.

•

Note: The real-time log session settings must already be saved to a config-

uration file in order to accomplish these steps.

Opening configuration file automatically using the Log Session Settings dialog:

• Select the Setup option from the Datalog menu (see Section 4.1).

• Fill in all of the information on this dialog.

• Click the Alarm Settings button and fill in the desired alarm settings.

• Click the Set as Default button.

•

A prompt is displayed to save the settings to a configuration file. Enter the filename for this configuration file (use a descriptive name).

•

A prompt is displayed to confirm setting this configuration as the default configuration file. Click Yes.

•

Click the Close button to close the dialog.

Test this feature to make sure it works properly by closing LogWa re and run

ning it again. The Log Session Settings dialog should be displayed with all of the configuration information filled in. If the configuration file is not being loaded, check the Defaults dialog as explained above.

To disable opening the configuration file on start-up, uncheck the Load default configuration file automatically check box on the Defaults dialog.

Starting a real-time log session unattended (delayed start)

2.3 Starting a real-time log session unattended (delayed start)

2 How to...

The main purpose of LogWare is to log data in real-time. Many times, the tech nician is present when a log session starts. However, sometimes it is necessary or desirable to start a real-time log session at off-hours when the technician is out.

LogWare has a feature called the Delayed Start which allows a real-time log session to start at a predefined date and time. By default, a real-time log session starts immediately when the Start button on the Log Session Settings dialog is clickedorwhentheStartoptionintheDatalogmenuisselected.

Setting the delayed start date and time for a real-time log session:

Select the Setup option from the Datalog menu to display the Log Session

tion.

• Set the Log interval and choose the appropriate End Log settings.

• Click the Delayed Start button to display the Delayed Start Date/Time di-

alog.

• Choose the date and time that the real-time log session should start. The start date and time are with respect to the computer’s clock settings. Make sure the computer’s clock is accurate. Click the OK button to accept the selected date and time.

Note: To cause the real-time log session to start immediately when click-

ing the Start button after having set a delayed start date and time, click the Reset button.

•

Fill in the Channels information to complete the setup process.

•

Click the Start button on the Log Session Settings dialog.

•

LogWa re displays a message indicating the date and time the real-time log session will start.

•

To cancel the delayed start, click the Cancel button at any time.

After a real-time log session ends, the delayed start time is reset so that the next real-time log session will start immediately when the Start button on the Log Session Settings dialog is clicked or when the Start option in the Datalog menu is selected. To set a new delayed start time for the next real-time log session, follow the steps above.

2.4 Stopping a real-time log session automatically

Note: Every effort has been made to make the real-time log session take

its first reading at the selected date and time. However, due to the large variation in the speed at which different computers operate, the first read ing may be one or more seconds later than the selected time (commonly known as “latency”). To compensate for this, try a few tests to determine the approximate latency in the computer being used and then adjust the start time accordingly by reducing the start time by the difference between the selected start time and the actual time of the first reading.

The main purpose of LogWare is to log data in real-time. Many times, the tech nician is present when a log session needs to be stopped. However, sometimes it is necessary or desirable to stop a real-time log session when the technician is busy with another task, or at off-hours when the technician is out.

The End Log feature of LogWare provides three methods for stopping a real-time log session:

• Manually, by the technician

• Automatically, after a specific number of readings

• Automatically, after a specific period of time

The first method, Manually, by the technician, is the default End Log setting.

Stopping the real-time session automatically:

• Select the Setup option from the Datalog menu to display the Log Session Settings dialog (see Section 4.1).

•

Fill in the Thermometer settings and Communication settings informa

tion.

•

Set the Log interval.

•

If needed, select the appropriate delayed start date and time.

•

Using the End Log drop down list, select the method to use to stop the real-time log session:

By user – Log session stops when the Stop option in the Datalog menu is selected

After specified # of readings – Log session stops automatically when number of readings specified have been logged

After specified time – Log session stops automatically after the specified time has elapsed

•

Specify the End Log criteria by selecting either the number of readings or the elapsed time

•

To start a real-time log session, the software must know what thermometer it is logging data from. Select the thermometer’s model number from the Model drop down list.

Enter the serial number of the thermometer in the Serial Number box. The se

rial number and the model number are both written to the header of the output file to indicate the instrument that was used to log the data.

Select the scale for the readings for this log session using the Readings Scale drop down list. The Readings Scale drop down list only displays the scales that are supported by the selected thermometer. To use the scale that the thermome ter is currently set to, select the <Keep Existing> option.

Select the COM port to which the thermometer is connected. This software ex pects to communicate with the thermometer via an RS-232 serial connection. Most laptop and desktop computers have at least one 9-pin or 25-pin COM port. Refer to your computer’s owner’s manual if you are unable to locate or identify a COM port on your computer.

Note: All Hart Scientific instruments require a “null modem” cable to in-

terface with a computer. Please refer to the thermometer’s User Guide for more information on this type of cable.

Each COM port is accompanied by a symbol that reflects the current state of the COM port as follows:

- COM ports with this symbol are available on this computer

and can be selected.

- COM ports with this symbol are virtual COM ports used to interface with an I/R port. This software does not support using COM ports with this associated symbol.

- The COM port with this symbol is currently being used by this software.

- COM ports with this symbol are in use by another application and cannot be used by this software at this time.

Select the baud rate that should be used to communicate with the thermometer. The available choices are determined by the baud rates supported by the se

lected thermometer.

Page 41

Note: The thermometer and this software must both be set to the same

baud rate in order to communicate successfully. Please refer to the ther mometer’s User Guide for more information on setting the baud rate of the thermometer.

Once the thermometer and communication settings have been selected, click the Test Communication button to attempt to establish communication with the thermometer and verify that the proper thermometer model is selected. If the software succeeds in communicating, a success message is displayed.

If the software is not able to successfully establish communication with the thermometer or if the software determines that the selected model does not match the model of the connected thermometer, a failure message is displayed indicating the reason for the failure. In case of failure, check to make sure that:

Setup log session

LogWare supports logging real-time data at intervals from 1 second to 24 hours. Select the desired interval using the Interval – Once every box.

Note: The maximum sample rate for Hart Scientific thermometer readouts

is one reading per second. Although every attempt is made, selecting a one second sample interval in this software does not guarantee that one read ing will be taken every second (because of processing overhead and calcu

lations that this software must perform between each reading). Typical tests have shown that, on average, this software can acquire about 9 read

ings every 10 seconds on a Pentium® class computer. Slower computers may not be able to log data at this rate.

If the real-time log session should automatically stop after a certain number of readings or after a specific amount of time, select the appropriate options from the End Log drop down list and specify the number of readings or time in the After boxes. If the real-time log session should continue until it is explicitly stopped, select the By User option in the End Log drop down list.

LogWare is capable of starting a real-time log session at a future date and/or time for unattended operation. The box to the right of the Delayed Start and Reset buttons indicate when the log is scheduled to start.

To start the real-time log session at a future date and/or time, click the Delayed Start button. The Delayed Start Date/Time dialog is displayed. The delayed

start date and time will be displayed in the box to the right of the Delayed Start and Reset buttons.

Note: Every effort has been made to make the real-time log session take

its first reading at the selected date and time. However, due to the large variation in the speed at which different computers operate, the first read

ing may be one or more seconds later than the selected time (commonly known as “latency”). To compensate for this, try a few tests to determine the approximate latency in the computer being used and then adjust the start time accordingly by reducing the start time by the difference between the selected start time and the actual time of the first reading.

To start a real-time log session immediatelywhentheStartbuttonisclickedon this dialog, click the Reset button. This will ignore any delayed start date/time and the log session will start when the Start button is clicked. The box to the right of the Delayed Start and Reset buttons indicates that the log session will start immediately.

The Channels list displays an item for every channel on the selected thermometer. Currently, LogWa re only supports thermometers with a single channel. To specify settings for a channel, click on the appropriate item in the Channels list.

Select the color to use for the trace on the graph using the Trace Color drop down list.

Enter the name of the output file that the logged data for the selected channel should be saved to in the Filename box. Choose a descriptive filename that identifies the data contained in the file. LogWar e automatically appends a .TXT extension on the end of the filename. The name of the output file is also used as the channel “label”. The channel label is a descriptive identifier assigned to a channel to give meaning to the readings being logged on that channel, instead of using only the channel number. By default, the filename is set to Channel N.txt (where N is the channel number).

Output files are written to the folder specified on the File | Defaults Folders tab. To change the folder where the output file will be saved for this log session, click the “…” (Browse) button on the right side of the Filename box. The Win dows® Save As dialog is displayed. Navigate to the desired folder and click the OK button.

Check the Overwrite existing file check box if this output file should overwrite any existing file with the same name in the selected folder. If this box is not checked, this software will display a prompt if a file with the same name exists and allow the filename for this output file to be changed. It is recommended that this check box NOT be checked to prevent accidentally overwriting output files.

Real-time log session

In order to optimize the logging of readings, many menu options are disabled during a real-time log session. Of course, once a real-time log session is run

ning, none of the settings can be changed, including the readings scale, alarm settings and events, and communication settings. Also, the Download menu op tions and Tools menu options are disabled, as well as the Open Previously Logged Data File option in the View menu.

If LogWare was configured to automatically stop logging data after a specific number of readings of after a specified amount of time, data will continue to be logged at the specified log interval until that condition is met. The Statistics box in the upper right corner of the Real-Time Log Session window displays the number of readings taken thus far and the elapsed time since logging started.

The real-time log session can be stopped manually at any time regardless of whether or not the log was configured to stop automatically by selecting the Stop option from the Datalog menu or by clicking the Stop icon on the toolbar.

Once the real-time log session has been stopped, the output file which contains all of the logged readings can be opened by selecting the Open Previously Logged Data File option from the View menu.

Note: Be aware that selecting any menu option while a real-time log ses-

sion is running may cause the measurement process to halt temporarily until the menu is closed or the dialog that is displayed is closed! Also, running other applications on the computer while logging real-time data, especially those that require a lot of processing time or that access the disk frequently, may cause the measurement process to halt temporarily while the other application is busy. It is recommended that, once a real-time log session is started, the software and the computer be left alone to log the data without interruption.

Alarms

The current alarm state is determined by comparing the most recent reading to the alarm settings. If the Low Alarm and/or High Alarm have been configured, the reading is compared to the low alarm and high alarm values. If the reading is less than the low alarm value and the low alarm is enabled, the Alarm box in the Channel information grid flashes Low to indicate the low alarm has “trip

ped”. If the reading is greater than the high alarm value and the high alarm is enabled, the Alarm box in the Channel information grid flashes High to indi

cate the high alarm has “tripped”. If the reading falls between the low and high alarm values or if the alarms are not enabled, the Alarms box remains blank (alarm reset).

Every time an alarm is tripped, a single entry is written to the alarm log file. This file is named “alarm.log” and is located in the default output folder or the folder that the output file is saved in.

The alarm log file can be viewed by selecting the Alarm Log from the View menu or by right-clicking on the Channels grid and selecting the View Alarm Log option from the popup menu.

Statistics

The Statistics section on the Real-Time Log Session window displays statistical information for the readings that have been logged. Each of the statistics can be enabled or disabled by simply checking or unchecking the appropriate check box. When a statistic is disabled, the box is left blank.

Clicking the Clear button resets all statistics, including the Count and Elapsed Time, and begins calculating the statistical data again from the next reading.

Readings Graph

As readings are logged, a trace is drawn on the graph to give a visual represen tation of the readings.

The Y-axis of the graph is always in the reading scale (units) selected on the Log Session Settings dialog. The Y-axis is automatically scaled to keep the en tire visible portion of the trace within the graph bounds.

The X-axis of the graph displays elapsed time since the log session started. As the trace reaches the right side of the graph, the trace shifts to the left and the left-most part of the trace is pushed off the graph. The graph is set to display 600 readings at a time. This setting is fixed and cannot be changed. Therefore, the graph displays anywhere from 10 minutes (at a 1 second sample interval) up to 600 days (at a 24 hour sample interval) of readings.

Note: The elapsed time shown on the graph is only an approximate time!

Anytime a menu option is selected or a dialog is displayed, data logging may be temporarily halted until the menu or dialog is closed. This causes the elapsed time to become inaccurate. The true elapsed time is displayed in the Statistics in the upper right corner of the window.

The 1522 Download dialog allows the user to select the settings for downloading Autolog or Demand log data.

Select log

Select the type of logged data to download. Refer to the thermometer’s User Guide for an explanation on the differences between the autolog and demand log data.

Download options

Select the download mode to use when downloading the data. When using the I/R dongle, the data can be downloaded in either binary mode or ASCII mode. When using the RS-232 serial cable, the Binary mode option is disabled.

Obviously, it would be preferable to download the logged data as fast as possi ble. However, the user must be aware that there are some trade-offs when using the Binary mode instead of ASCII mode to download the data. Please read the following to understand these trade-offs:

Page 56

ASCII Downloading Binary Downloading

Speed Disadvantage: Downloading data in ASCII mode is in

herently much slower than Binary mode because more information (bytes) must be sent for each reading. Typically, ASCII mode requires that 40 bytes be sent (which includes the date, time, value, scale and label) for each reading. Therefore, to download 10,000 read ings in ASCII mode requires the thermometer to send 400,000 bytes (approximately 390KB) of information to the software.

5 Download menu

Download logged data

Advantage: Downloading data in Binary mode is much

faster than ASCII mode because the information can be compacted into fewer bytes for each reading. Typically, Binary mode requires that only 10 bytes be sent (which also includes the date, time, value, scale and label) for each reading, plus a few bytes for over

head information. Therefore, to download 10,000 read ings in Binary mode requires the thermometer to send approximately 100,000 bytes (approximately 98KB) of information to the software, which is only 25% as much information than in ASCII mode making the sig nificantly faster! (see table below)

Transmission Error Detection

Rounding and Truncation Errors

Disadvantage: In ASCII mode, the software has diffi culty knowing whether or not all readings have been received. The software attempts to determine if any readings are missing by comparing the total readings received to the number of readings the thermometer says were sent. If there is a difference, an error mes sage is displayed alerting the user to download the data again. This technique does not catch all types of errors, however.

Advantage: In ASCII mode, the thermometer sends the actual digits of each reading including the date, time, value, scale and label number. No translation is required. The readings are simply written to the download file as received.

Advantage: In Binary mode, the 1522 first sends out a

header packet which is basically some information about how many readings are to be sent. Then the readings themselves are sent. Following the readings, another packet of information is sent which contains a checksum. This checksum is compared to a checksum

which is calculated by the software to determine if all readings were received properly, without error. If an error is detected, an error message is displayed alerting the user to download the data again. This is a very good error checking technique which eliminates nearly all transmission related errors.

Disadvantage: In Binary mode, the thermometer sends a binary representation of each reading including the date, time, value, scale and label number to the software. The software must then translate each reading into the actual date, time, value, scale and label number before writing it to the download file. This technique tends to introduce minor errors because of rounding and truncation errors in floating point num bers. Typically, these errors are on the order of 1mK which is well out of the specification of the 1522 LLL Handheld Datalogger. These errors do not occur on the date, time, scale and label number, only the value of the reading.

For complete information on the extent of the error in troduced by these discrepancies, please see Section

File options

The File Options allow the user to determine how to write the downloaded data to download files.

Write all readings to a single file – All downloaded readings can be written to the same file by selecting this option. Selecting this option creates one down

load file with the name OUTPUT.TXT and saves the file in the folder specified below. All downloaded readings, regardless of the assigned label, are written to this one file. It is highly recommended that this option be selected when down

loading Demand Log data.

Write readings to separate files – Downloaded readings can be written to multiple files by selecting this option. As readings are downloaded, one file is created for each unique label that has been assigned to a reading. All readings that were assigned a given label are written to the same file regardless of whether the readings are contiguous (all together) or spread throughout the log. The filenames of the download files in this case consist of the label followed by a .TXT extension. All files are saved in the folder specified below.

Note: Be careful using this option if no label was assigned to some or all

readings. If no label is assigned to a reading, the reading is given a numerical label indicating the reading number. When writing readings to separate files based on the label, one file will be created for each reading! If 100 readings were downloaded, the software may attempt to create 100 separate files with one reading in each file!

The other file options allow the user to decide how to handle overwriting existing files in the selected folder.

Prompt to enter all filenames – Checking this option causes the Windows® Save As dialog to appear before each download file is created to allow the user to either change the filename or folder to which the file will be written. When writing readings to separate files, checking this option could become very time-consuming if many files need to be created. If this option is checked, the Prompt before overwriting existing files option is disabled.

Prompt before overwriting existing files – This option is only enabled if the Prompt to enter all filenames option is not selected. Checking this option causes the Windows® Save As dialog to appear ONLY when the software at

tempts to create a download file that has the same name as an existing file in the selected folder. The user can either select a different folder or change the name of the file to avoid overwriting the existing file. Leaving this option un

checked will automatically overwrite any existing files that have the same name as the download files. It is recommended that this option always be checked.

The Write files to box allows the user to select or enter the folder to which the download files should be written. This folder defaults to the download folder that is selected on the File | Defaults Folders tab. If the folder to which the download files should be written already exists, use the ‘…’ (Browse) button to

5.3 Download Process

The download process consists of the following steps:

•

Check communication – Before any downloading begins, the software checks to make sure it can communicate with the thermometer. If commu nication succeeds, the download process continues. Otherwise, an error message is displayed and the download process is aborted.

•

Read data labels – The current data labels are read in from the thermom eter. When downloading readings, the data label number is downloaded as opposed to the label itself to improve the total download time. As read ings are parsed, the label number is replace with the appropriate label.

•

Download readings – Next, the software begins to download the actual readings including the date, time, value, scale and label index. Depending

Page 60

5 Download menu

Download Process

on how many readings are being downloaded and the selected download options, this process could take anywhere from 2 seconds to over 20 min utes.

Note: For binary downloads, please read Section 5.4 Binary Download

Discrepancies.

Parse readings – After all readings have been downloaded, the software

•

parses the data. This process includes translating binary data into ASCII text (if the readings were downloaded in Binary mode) and breaking up the date, time, value, scale and label into separate entities in preparation to write the readings to the download file(s). This process also includes re

placing the label number associated with each reading with the actual la bel text.

Write readings to file(s) – The last step of this process is writing the

•

readings to the download file(s) based on the selected file options.

If an error was detected during the download process, an error message will be displayed and the download process will be aborted. The user may also abort the download process by clicking the Cancel button on the progress indicator that is displayed during the various operations.

Note: Anytime the download process is aborted, it is recommended that

the thermometer be powered off then back on again. This is the only way to force the thermometer to abort the download process.

If the download process completes successfully, the Downloaded Files dialog (Figure 26) is displayed.

5.4 Binary download discrepancies

This dialog shows a list of all files that were created by the download process including the location of each file. Any of the files listed can be opened in the Windows® default text editor by double-clicking on the appropriate entry in the list.

Click the OK button to close this dialog.

The Model 1522 LLL Handheld Datalogger has built-in RS-232 and I/R ports. LogWare supports both interfaces for downloading logged readings from the memory of the 1522. Using the RS-232 serial interface, the readings can only be downloaded in ASCII mode (all readings are downloaded as text). However, when using the I/R interface, the readings can be downloaded in either ASCII mode (text) or in binary mode. Binary mode has many advantages over ASCII mode, but also has some disadvantages.

Binary mode advantages

The major advantage of using binary mode to download readings is speed, which translates into time. The 1522 is capable of logging up to 10,000 readings in its autolog. Downloading these readings (which consist of the date, time, value, units and label index) in ASCII mode can take up to 20 minutes or more at the fixed baud rate of 2400 baud. Binary mode both reduces the number of bytes that need to be sent per reading and uses a higher baud rate (115,200 baud) to significantly reduce the download time. See the table below for details:

Download Mode and Interface Approx. Download Time for

I/R – Binary mode 90 seconds

I/R – ASCII mode 22 minutes

RS-232 – Binary mode Not Applicable

RS-232 – ASCII mode 22 minutes

10,000 Readings

Also, binary mode adds some error detection to ensure that readings are prop erly transmitted.

Binary mode disadvantages

The major disadvantage of using binary mode is that it introduces small dis crepancies into the readings due to rounding and truncation errors. The read

ings that are transmitted to the PC in binary format are “encoded” and must be “decoded” once they are received. This decoding sometimes introduces small errors into the readings. Typically, these errors are on the order of 1mK which is well within the specification of the 1522 LLL Handheld Datalogger. These errors do not occur on the date, time, units or label index, only the value of the reading. The following table indicates maximum observed errors at various resistances and conversion settings:

The Y-axis of the graph is always in the reading scale (units) in which the read ings were written to the file. The Y-axis is automatically scaled to keep the en

tire trace within the graph bounds.

The X-axis of the graph displays an approximate time scale. As the readings are read from the file, the software calculates the time interval between each reading. After the entire file has been read in, the software uses the average in terval between all readings as the interval between each point. For this reason, if all of the readings in the file are not separated by the same time interval, the graph will not be 100% accurate.

Note: The readings graph is only capable of displaying up to 32,767 read

By default, the X-axis is set to Bottom and the Y-axis is set to Left.

Scale

The Scale options allow the user to determine the minimum and maximum val ues for an axis. Each option is described below:

Zero origin – This option draws the selected axis including the origin (zero) and extending far enough in the positive and negative directions to include all of the graph’s values

Variable origin – Select this option to have the axis “zoom in” on the range of the graph’s actual values, whether or not that range includes zero.

User-defined – This option allows the user to set values for the minimum, maximum, and number of ticks for the axis. When this option is selected, the settings in the Range group are enabled

By default, the X-axis and Y-axis are both set to Variable Origin.

Note: Changing the Scale settings (especially for the X-axis) while ac-

quiring real-time data could possibly cause graphing problems to occur. Therefore, it is recommended that these settings NOT be changed by the user when acquiring real-time data.

Range

The Range options are only enabled if the User-Defined option is selected in the Scale options for the selected axis. Enter the Maximum and Minimum val

ues for the selected axis. The selected axis is rescaled to the settings entered.

The Ticks option allows the user to determine how many major tick marks should be displayed between the minimum and maximum values on the se

lected axis. Each major tick mark is labeled with the appropriate value. The tick marks themselves are only displayed if the Show check box in the Tick Marks controls is checked.

By default, these settings are not used by the software because of the default Scale settings.

Tick marks

The Tick Marks options allow the user to specify whether or not to show tick marks on the selected axis. To show tick marks, check the Show check box. If this check box is not checked, the tick marks are not shown on the selected axis. Valid settings are between 1 and 1000.

The Every option is only enabled for the X-axis. This option determines how often major tick marks appear on the X-axis. When acquiring real-time data, the graph displays the most recent 600 readings acquired. The Every option is

set to 150 meaning that a major tick mark appears every 150 readings, or 600 divided by 150 = 4 major tick marks appear on the X-axis. When analyzing previously acquired data, the Every option is calculated by the software de

pending on the number of readings being displayed. The X-axis must end with a tick mark. If you set an Every value that doesn’t include the last value on the axis, the graph will extend the X-axis so that it ends on a tick mark.

The Minor option allows the user to determine how many minor tick marks ap pear between each major tick mark. By default, the X-axis and Y-axis are set to display 5 minor tick marks between major tick marks. Valid settings are be

tween 0 and 100.

The Through Axes, Inside Axes and Outside Axes options allow the user to specify how the tick marks should be drawn on the axis. By default, both the X-axis and Y-axis are set to Through Axes.

Statistical lines

These options allow the user to specify which statistical lines should be dis

played on the graph.

Check the All Sets option to apply the statistical lines settings to all of the sets (traces) on the graph. When this check box is checked, the Set Number controls are disabled.

The Set Number box allows the user to select which set (trace) to which to ap

ply the statistical lines settings. This setting can only be changed if the All Sets check box is not checked.

Note: This software only has one set of data. When acquiring real-time

data, this set is the data being acquired. When analyzing previously ac

quired data, this set is the data which was previously acquired.

Check the Mean check box to enable a mean line, which is drawn horizontally through the average value of all data points in the selected set.

Check the Min/Max check box to enable min and max lines, which are drawn horizontally through the lowest and highest data points in the selected set.

Check the Std Dev check box to enable a pair of standard-deviation lines, which are drawn horizontally through the standard deviation from the mean (in both the positive and negative directions) for the selected set.

Check the Best Fit check box to enable a best-fit line, which is a straight line indicating the trend of data points (a first-order polynomial curve) for the se

lected set.

Check the Curve Fit check box if you want to fit a curve through your data points for the selected set. You can choose the type, order and granularity of the curve in the Curve Fit options below. These settings will apply to all curve fit lines drawn on the graph.

By default, no trend lines are enabled.

Curve fit

Select the curve fit options for the curve fit statistical line. The following options are available:

Curve Type Variable-Order Polynomial

Logarithmic y = a + b * log(x)

Exponential 1 y = a * exp(b * x)

Exponential 2 y = a * x * exp(–b * x)

Power y = a * (x ^ b)

Inverse1 y=a+b/x

Inverse 2 y = a / (b + x)

Inverse 3 y = 1 / (a + b * x)

Inverse 4 y = x / (a * x + b)

Inverse 5 y = 1 / (a + b * x) ^ 2

Spline Spline fit through all points

averaged group

Page 80

7 Graph menu

Graph settings

The Order option applies only to three curve types:

For variable-order polynomial curves, Order is the order of the polynomial used in curve fitting. A setting of 1 produces a straight line (the same as a best-fit line); a setting one less than the number of points produces a curve that passes through every point

For moving-average mid and moving-average end curves, Order is the range of data points over which moving averages are averaged, beginning with the first point

The Granularity scroll bar sets the granularity of all curve types except mov

ing-average. The granularity is the number of “steps,” or straight line segments, making up the curve. Higher values create smoother curves, but require more drawing time. The default Granularity setting is 50 curve steps, which generally creates a smooth-looking curve at a high drawing speed. Each click to the left decreases the number of steps by 2 (to a minimum of 10), and each click to the right increases the number of steps by 2 (to a maximum of 1000). With spline curves, you generally need higher granularities than normal—up to 10 times the number of points in the graph.

Color

Select the colors for each of the statistical lines to display on the graph. The selected color for each statistical line applies to that statistical line for all sets of data.

Limit lines

Select the limit (alarm) lines options to display on the graph. To display the high alarm line, check the High check box. To display the low alarm line, check the Low check box.

By default, the low and high limit values are set to the low and high alarm val ues entered on the Alarm Settings dialog. The limit lines, however, are not dis

played by default.

Note: Changing the low and high limit line settings on this dialog DOES

NOT change the low and high alarm settings entered on the Alarm Set

tings dialog and therefore does not affect the alarm events options. These settings are only used to display the alarm lines on the graph. Only change these settings if absolutely necessary.

Select the line style for the limit (alarm) lines using the Line drop-down list. A fill pattern can also be selected using the Fill drop-down list. Select the color of the limit (alarm) lines and the fill pattern using the Color drop-down list.

Select the Fill Opposite check box to fill the area between the High and Low limit (alarm) lines with the selected pattern. If this option is not checked, the ar eas above the High limit value and below the Low limit value are filled in with the selected pattern.
