Verifying AC voltage
Check AC voltage accuracy by applying accurate AC voltages at specific frequencies from
the AC voltage calibrator to the Model 7700 inputs and verifying that the displayed readings
fall within specified ranges.
CAUTION
Do not exceed 300V RMS between plug-in module INPUT H and L
terminals or between adjacent channels, or 8

V•Hz input, because
instrument damage may occur.
Follow these steps to verify AC voltage accuracy:
1.
Connect the Model 7700 CH1 H and L INPUT terminals to the AC voltage calibrator as
shown in
