5. Source positive and negative and full-scale voltages for each of the ranges listed in
Table 1-2. For each voltage setting, be sure that the reading is within stated limits.
Verifying AC voltage
Check AC voltage accuracy by applying accurate AC voltages at specific frequencies from
the AC voltage calibrator to the Model 2700 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

V•Hz input, because instrument damage may occur.
Follow these steps to verify AC voltage accuracy:
1. Connect the Model 2700 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.
