AC Volts Measurement Test

To prevent possible electrical shock, fire, or personal injury:
•
•
1. Put the calibrator in Standby (STBY) mode.
2. Put the UUT rotary switch in the S position.
3. Connect the calibrator to the COM and
4. Apply the values from the calibrator shown in Table 11 and compare the readings on

Some of the calibration verification tests involve the use of high
voltages and should be performed by qualified personnel only.
Always place the calibrator in the Standby (STBY) mode between
tests and before handling the test connections or test cables.
