6.
Slowly turn the Voltage Adjust on the front panel clockwise until the current flowing on the
external current meter (mA scale) equals the number showed on the front meter of the HT-
20KVPac unit, then, press the Test button and the front display will show “hold” for a few
seconds, wait until the front display show again "L1" again.
7.
Select the bottom calibration leakage point by pressing the
Reset
button until L2 is shown
on the front display of the HT-20KVPac unit.
8.
Turn the Voltage Adjust on the front panel to minimum. Press the
Test
button and a
leakage number will be displayed on the front panel meter (1.0). Be careful as the HT-
20KVPac will be putting out voltage at this point.
9.
Slowly turn the Voltage Adjust on the front panel clockwise until the current flowing on the
external current meter (mA scale) equals the number showed on the front meter of the HT-
20KVPac unit, then, press the Test button and the front display will show “hold” for a few
seconds, wait until the front display show again "L2" again.
10. Turn Off the HT-20KVPac tester.
11. Confirm the new leakage current calibration performing again the Leakage Current
Verification procedure, mentioned before.
