Usage

The following is a basic example of using the nidmm module to open a session to a DMM and perform a 5.5 digits of resolution voltage measurement in the 10 V range.

import nidmm
with nidmm.Session("Dev1") as session:
    session.configure_measurement_digits(nidmm.Function.DC_VOLTS, 10.0, 5.5)
    print("Measurement: " + str(session.read()))

Other usage examples can be found on GitHub.
