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-Hour settling time is required.
(2) 48-Hour settling time is required; should the sensor be equipped with an external polarisation battery, the settling
time is reduced down to 2 hours.

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).
ATTENTION
While rotating the sensor, take care not to apply any pressure onto the printed circuit abov e: apply
pressure onto the plastic body only.
