Please check the following:
The calibration sensor is connected properly to the µΩ input. (Mind the polarity.)
The calibration sensor is included properly in the circuit, and the arrow indicator matches the flow of current.
(Pointing from positive to negative.)
The calibration sensor supply voltages are correct (±15 VDC).
The calibration sensor output signal reacts to flowing current.

If problems persist, please contact Megger technical assistance.
12.2.4 Step 2/6 - CALIBRATION OF OUTPUT FACTOR
This dialog calibrates the output factor.
The calibration is performed by injecting 80% of the maximum available current.
Press ‘Calibrate CF OUT’ to perform the calibration.
The output factor will be adjusted according to the calibration sensor measurements. When finished, the resulting
value is displayed:
