1-10 Performance Verification Model 2701 Service Manual
Verifying AC voltage
Check AC voltage accuracy by applying accurate AC voltages at specific frequencies from
the AC voltage calibrator to the Model 2701 inputs and verifying that the displayed readings
fall within specified ranges.
CAUTION Do not exceed 1000V peak between front terminals INPUT HI and
INPUT LO, or 8
× 10
7
V•Hz input, because instrument damage may occur.
Follow these steps to verify AC voltage accuracy:
1. Connect the Model 2701 HI and LO INPUT jacks to the AC voltage calibrator as shown
in Figure 1-2. Be sure the INPUTS switch is in the FRONT position.
