4 Calibration, Verification, and Service
DMM Configuration
For all tests besides the DC Voltage and Current tests, the DMM should be set to measure AC volts and
100 NPLCs. For the DC voltage tests, the DMM should be set to measure DC volts and 100 NPLC.
Constant Voltage Tests
If more than one meter or a meter and an oscilloscope are used, connect each to the sense terminals
by separate leads to avoid mutual coupling effects.
