the PC. Run the bat le “WPI_EVOMCNX_3.E.bat.” The program will query the COM
ports in use and inform you as to which port the EVOM™ Manual is connected.
4. Enter the lename for the Output File (ENTER for WPI_EVOM™ Manual.csv). Type
in a lename and add the .csv extension or enter to accept the default.
5. Enter the time between readings in seconds. (Press Ente r for minimum delay.)
Enter a time of 0, 1, 2 or 5 seconds. (0 is fastest at about 0.3 seconds.) The
program will run and update until ^X (control X) is typed. The readings are
continuous at 12.5 Hz, always on. The time entered is the averaged reading taken
at that time interval.
6. The default le name is WPI_EVOM™ Manual.csv. This le may be opened in
