WPI_EVOM3CNX.py

Run in a bat file as: python WPI_EVOMCNX.py
Refer to to the EVOM3 manual Appendix C.

This routine: This routine records a sequence count of averaged data to a CSV file on the USB drive with a wait until stopped.


Records samples with an averaging rate of 1-999 seconds.
Takes 1 to 65000 resistance or voltage samples and writes each record to the file and display.

Wait X time in minutes (0-360) and show the remaining wait time (in minutes, seconds?) on the display if greater than 1. The mode is changed over to reading mV during the wait, this is done so as not to take resistance samples continuously as that can stimulate the tissue over time. Resume the resistance or mV mode activity and repeat until manually stopped.


Enter file name, the default is WPI_EVOM3.csv:
Enter time between measurments 0-999 seconds:
Select number of data points to record 1-65000:
Select wait time between data sets 1-360 minutes:

Conditions
1. When you switch from Resistance to Voltage, the “Mode:” tag on the EVOM3 screen remains in what it originally was and doesn’t update. 
2. Once you switch from Resistance to Voltage and Back, the units “OHMS” or “mV” doesn’t update correctly on the screen, the data on the EVOM3 screen is correct. 
3. If you send the EVOM3 the command to wait a long time between readings, say 60 secs [ X 60 ]. The EVOM3 “waits” first and then provides data.
