Performance Test Procedures
Table 1 is a list of the standard equipment for the Performance Tests.
All procedures refer to the performance tests and the readout limits in Table 2.
AC Voltage
To verify ac voltage:
1. Connect the normal output HI and LO of the calibrator to the V Ω and COM input
connections on the bottom of the device under test (DUT).
2. Set the DUT to V (AC Volts measurement mode).
3. Set the calibrator NORMAL output to the voltage and frequency.
4. Apply the voltage to the DUT:
a. Verify that the DUT reads within the display limits.
b. Verify the DUT readings for the remaining steps for AC voltage.
