Verifying AC current
Check AC current accuracy by applying accurate AC voltage current at specific frequencies
from the AC current calibrator to the Model 2701 input, verifying that the displayed readings
fall within specified limits. Follow these steps to verify AC current.
1.
Connect the Model 2701 AMPS and INPUT LO jacks to the calibrator as shown in
Figure 1-4
. Be sure the INPUTS switch is in the FRONT position.

Connections for Model 2701 AC current verification
2.
Select the AC current function by pressing the
ACI
key.
3.
Set the Model 2701 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.
