AC voltage calibration
Follow these steps for AC voltage calibration:
1. Connect the calibrator to the Model 2701 INPUT HI and LO terminals as shown in
Figure 2-4 .
2. Perform the calibration steps summarized in Table 2-11 . For each step:
• Set the calibrator to the indicated voltage and frequency, make sure the unit is in
operate. (You must use the stated voltage and frequency.)
• Send the indicated programming command.
• Wait until the Model 2701 completes each step before continuing.
