7. To calibrate Insulation Resistance range
Please connect a 100k standard resistor across the HV and RETURN connectors.
Press the Up () or Down () arrow keys until the display shows:
Then press the TEST button on the front panel. The tester will execute automatic calibration process. The
process does not require data entry. The tester will provide around 300VDC on the output connectors and the
display will show:
The tester will output one short “beep” and advance to the next calibration point when the automatic process
is completed successfully, otherwise the tester will output two short “beeps” and will not advance to the next
calibration point.
When previous calibration point was completed successfully display will show:
Please connect a 1M standard resistor across the HV and RETURN connectors.
Then press the TEST button on the front panel. The tester will execute automatic calibration process. The
process does not require data entry. The tester will provide around 300VDC on the output connectors and the
display will show:
