CALIBRATION
Please connect a 50M standard resistor across the HV and RETURN connectors.
Then press the TEST button on the front panel. The instrument will execute automatic
calibration process. The process does not require data entry. The instrument will provide
around 1000VDC on the output connectors and the display will show:
The instrument will output one short “beep” and advance to the next calibration point
when the automatic process is completed successfully, otherwise the instrument will
output two short “beeps” and will not advance to the next calibration point.
9. To calibrate Insulation Resistance high range
When previous calibration point was completed successfully display will show:
The 50M standard resistor should be connected across the HV and RETURN
connectors of the instrument.
Then press the TEST button on the front panel. The instrument will execute automatic
calibration process. The process does not require data entry. The instrument will provide
around 150VDC on the output connectors and the display will show:
The instrument will output one short “beep” and advance to the next calibration point
when the automatic process is completed successfully, otherwise the instrument will
output two short “beeps” and will not advance to the next calibration point.
10. To calibrate Ground Bond test voltage
Please connect a standard 6V AC Voltmeter across the CURRENT and RETURN
connectors of the instrument.
Press the Up () or Down () arrow keys until the display shows:
Then press the TEST button on the front panel. The instrument will generate an output of
about 6 VAC and the display will show:
09. IR 999.9M
Load = 50M
