Multiple Session Support
Depending on the length of your modeling sessions, it is often possible to record multiple runs into the eLogger without having to
clear the buffer or overwrite data. The eLogger software will split multiple sessions automatically for you. By clicking the
“Sessions” option in either the playback or graphing pages of the software, you can display a separate session, or all sessions
simultaneously. When graphing all sessions simultaneously, vertical gray bars on the graph indicate where sessions start.
Note that a new session is created in the logger each time it is powered off and on.
Saving eLogger Log Files
After downloading session data, if you wish to save the data to play back later or to share with friends, save the file with the
“File/Save Recorder File” menu. Note that the file is saved with a .FDR extension by default.
Clearing the eLogger’s Memory Buffer
After downloading data, you can clear the eLogger’s memory buffer if desired, to ensure there will be enough space for your next
sessions. To do this, just click the “Clear Recorder”button in the “Recorder Data Operations” section of the main software screen, or
click “Data, Clear Recorder Buffer.”
Combining Log Files
To combine two or more log files, simple open one of them using “File, Open Recorder File” and then combine with others by
selecting “File, Combine Recorder Files.”
USB Live Mode Bench Testing
When the eLogger is installed in your power system, and is also connected to your PC via the USB cable, clicking the Live Mode
button in the Windows software will cause the numeric displays and gauges to display data live. Live Mode sessions can be
recorded on the PC. To set up Live Mode recording, click “Software, Set Live Mode Options.” If Live Mode recording is enabled,
you will be prompted to save the recorded data when you stop live mode by clicking “Stop.”
Also, note that real time strip charting is also supported in Live Mode. To see real time strip charts, first turn on Live Mode
recording. Then, click “Graph Data” to launch the graph. Configure the parameters you want to see on the chart, and then click the
Live Mode button. Live data will be graphed on the chart!
Graphing/Spreadsheet Compatibility
The eLogger software has extensive graphing capability built in. Just click “Data, 2D Chart” in the software to graph loaded data.
Note that individual sessions of the file can be graphed separately, or side by side, by clicking one or more sessions to graph in the
“Sessions” menu. Side by side graphing lets you compare performance across different laps, or with different log files if the
“Combine Recorder Files” option is used as described above. Click on the HELP button on the graphing page for more information
on graphing.
