(PYTHON) ON A PC
The program on the USB thumb drive is a self-executing program to record serial data
through a USB cable to a Window PC computer. This is intended to record continuous
measurements of a single sample. The following files are included on the USB stick:
•
CDM v2.12.28 WHQL Certified EVOM3 USB driver for Windows
•
Python.exe Python recording program and other support folders for
Windows
•
Read_EVOM3_3.E.bat Batch file for executing the recording program
•
WPI_EVOMCNX_3.E.py Python EVOM3 USB digital recording program
•
WPI_EVOM3.csv Sample recording file
NOTE
: An out of resistance range indication on the
EVOM3
screen will show -----.
The Python output will list -99999.9. If you are using a lower range (10K or 50K), stop
the output (X), increase the range and restart. The maximum resistance level that the
EVOM3
can measure is 10,5000 ohms.

ports in use and inform you as to which port the
EVOM3
is connected.
