(5) Set the variable supply voltage to 30V ±0.1V and enter the measured full-scale
voltage:
(6) Press the ENTER key to accept the calibration. Press the EXIT key four times to
quit the CALIBRATION and SETUP modes.
(7) Verify the instrument calibration by applying the test voltages given in Table 2 to
the voltmeter (after both voltage ranges have been calibrated).
(8) Disconnect the calibration/test equipment.
