AC voltage calibration
Follow these steps for AC voltage calibration:
1. Connect the calibrator to the Model 2010 INPUT HI and LO terminals as shown in
Figure 2-4.
2. Perform the calibration steps summarized in Table 2-6. For each step:
• Set the calibrator to the indicated value, and make sure the calibrator is in operate.
• Press ENTER to complete each step.
• Wait until the Model 2010 completes each step.
NOTE Do not exceed ±15V peak between sense LO and LO. You may have to remove the
external sense leads before calibrating AC volts. Even though some calibrators can
turn off their external sense, the AC voltage can still cause excess voltage to appear
between sense LO and LO.
