calibration menu without changing the calibration setting. Press the EXIT key to exit
from the calibration mode and to return to the test mode.
6. To calibrate Insulation Resistance low 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 instrument will execute automatic
calibration process. The process does not require data entry. The instrument will provide
around 300VDC 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.
7. To calibrate Insulation Resistance mid range 1
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 instrument will execute automatic
calibration process. The process does not require data entry. The instrument will provide
around 300VDC 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.
8. To calibrate Insulation Resistance mid range 2
When previous calibration point was completed successfully display will show:
06. IR 0.99M
Load = 100k
