Rotate the sensor clockwise until hearing a click (See point 4).
8
While rotating the sensor, take care not to exert any pressure onto the printed circuit
above: exert pressure onto the plastic body only.
Reconnect the sensor (See point 3).
9
Close the back door of the sensor compartment again, and tighten screws again (See point 1).
10
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.
