AC Voltage

To verify ac voltage:
1. Connect the test leads to the V Ω and COM input terminals on the bottom of the device
under test (DUT).
2. Connect the other end of the test leads to the NORMAL output HI and LO terminals on the
Calibrator.
3. Set the DUT to
4. On the Calibrator:
a. Set the desired voltage and frequency at the NORMAL output terminals.
