Insert the new sensor paying attention to match the sensor connectors with the relevant supports on the
6
circuit board.
Place back the tubes (See point 4).

Close back the base of the instrument and screw back the four screws (See point 2).

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.
