Calibration 2-21
AC voltage calibration
Follow these steps for AC voltage calibration:
1. Connect the calibrator to the Model 2015 INPUT HI and LO terminals as shown in
Figure 2-4.
2. Perform the calibration steps summarized in Table 2-12. For each step:
• Set the calibrator to the indicated voltage and frequency, and make sure the unit is
in operate. (You must use the stated voltage and frequency.)
• Send the indicated programming command.
• Wait until the Model 2015 completes each step before continuing.
