Figure A-2. AC Voltage Characterization.
(3) Set AC measurement standard to INPUT 2, EX GRD on.
NOTE
The GUARD status must be refreshed when the AC
measurement standard changes from the 220 V range to any
higher range. To refresh, press the EX GRD key twice (once to

(6) Set calibrator voltage/frequency to the first settings in table A-3, output to OPR.
(7) Record the AC measurement standard indication in the True Applied column in
(8) Repeat technique of (5) through (7) for remaining AC measurement standard
ranges and calibrator output voltages/frequencies in table A-3.
(9) Set the calibrator output to minimum and disconnect equipment set-up.
