Calibration Procedure
7-13
■ Connect a 10MΩ 0.5 Watt or high power simulated load resistance in between the
high voltage output terminal (HV OUTPUT) of the channel to be calibrated on this
Tester and the high potential terminal of AC meter, also connect the low potential
terminal (RTN/LOW) of the channel to be calibrated on this Tester to the low
potential terminal of AC meter.

1. Press START to output voltage and read the data from the AC meter.
2. Press numeric key 0 . ~ 9 to input the reading of AC meter.
3. Press ENTER to confirm the input.
4. Press STOP to stop high voltage output.
5. Press ▼ to go to ACA 3mA FULL (2.4mA) calibration.
■ Change the simulated load resistance to 500kΩ 10watt or higher power.
