Turn on the instrument to check the new sensor works correctly through the menu "Sensor Troubleshooting".
It is normal if a newly installed sensor gives a 'current error': it is necessary to wait some time, so that the sensor
polarization can settle. The table here below shows the minimum settling time for each sensor.
Note:
(1) 2 hours’ settling time is recommended.
(2) 48 hours’ settling time is recommended; should the sensor be equipped with an external polarization battery, the
settling time is reduced down to 2 hours.
(3) 1/2-Hour settling time is recommended.

Reconnect the sensor (See point 3).
10
Close the back door of the sensor compartment again, and tighten screws again (See point 1).
8
Rotate the sensor clockwise until hearing a click (See point 4).
While rotating the sensor, take care not to exert any pressure onto the printed circuit
above: exert pressure onto the plastic body only.
