1-12 Performance Verification
Verifying AC current
Check AC current accuracy by applying accurate AC voltage current at specific frequencies
from the AC current calibrator to the Model 2700 input, and verifying that the displayed read-
ings fall within specified limits. Follow these steps to verify AC current:
1. Connect the Model 2700 AMPS and INPUT LO jacks to the calibrator as shown in
Figure 1-4. Be sure the INPUTS switch is in the FRONT position.

2. Select the AC current function by pressing the ACI key.
3. Set the Model 2700 for the 1A range.
4. Source 1A and 3A, 1kHz full-scale AC currents as summarized in Table 1-5, and verify
that the readings are within stated limits.
