1-10 Performance Verification
Verifying AC voltage
Check AC voltage accuracy by applying accurate AC voltages at specific frequencies from
the AC voltage calibrator to the Model 2015 inputs and verifying that the displayed readings fall
within specified ranges.
CAUTION Do not exceed 1100 V peak between 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 2015 HI and LO INPUT jacks to the AC voltage calibrator as shown
in Figure 1-2.
