Set the Calibrator Mainframe to the Volt menu. Press on the Calibrator Mainframe
to activate the output. Then follow these steps to verify ac voltage frequency.
1. Set the PM 6680's FUNCTION to measure frequency on channel A with auto
2. Using the N to BNC cable, connect the CHAN 1 connector on the Calibrator
3. Program the Calibrator Mainframe to output 2.1 V at each frequency listed in Table
4. Allow the PM 6680 reading to stabilize, then record the PM 6680 reading for each
