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.
The eLogger's Data File is compatible with Excel ™ spreadsheet software, and other spreadsheet products supporting space delimited
data files. Using Excel™ is useful for graphing the data output from the eLogger.
To load in Excel, save the data file from "File->Save Recorder File," and in Excel™ choose File->Open, and select "All Files" in the
"Files of Type" box. Navigate the Excel dialog box to the location where you saved the .FDR data file, and click on the filename.
Excel should then bring up the "Text Import Wizard". Choose the "Delimited" option, and on the next page choose "Delimited with
Spaces". The data should then load correctly in Excel.
