7.5.2 DCA Current Calibration
■
Connect a 10M
0.5 Watt or high power simulated load resistance between the
high voltage output terminal (HV OUTPUT) of the channel to be calibrated on this
tester and the high potential terminal of the AC meter. Connect the low potential
terminal (RTN/LOW) of the channel to be calibrated on this tester to the low
potential terminal of the AC meter.
