AC Voltage and AC Current Calibrations
The AC voltage and AC current calibrations consist of the half range calibration and
gain calibration. You should first perform the half range calibration and then perform
the gain calibration. The introductions below illustrate the calibration procedures by
taking the AC voltage 200 mV scale as an example.
1. Read the "Calibration Devices" and "Test Conditions".
2. Press
to select the AC voltage measurement function. Set the range to the
200 mV scale and set the reading rate to "Slow".
3. Press ; press T/C  PSW and input the correct calibration password; set
SecrOff and press Cal  Enter.
4. Connect the voltage output terminal of the calibrator with the HI-LO input
terminal of the multimeter. Set the calibrator to output a 100 mV, 1 kHz sine
waveform (namely the half range calibration output). Turn on the output of the
calibrator and wait until the output of the calibrator becomes stable. Then, press
Middle to perform the half range calibration; the half range calibration
parameters will be displayed in the Cal M table after the half range calibration
finishes.
