Changing the sensor unit

For changing the sensor unit, carry out the following Steps:

• Power down the P2 (remove the fuse, observing the hints below)

• Remove screws

• Take off SmartSensor as indicated below

• Pull the connector off the SmartSensor

• Fit the replacement SmartSensor

• Power up the P2 (insert fuse observing the hints below)

Note:

To precisely determine SF6 concentration, SF6 AREACHECK P2 requires a reference value representing

clean air. This reference value is taken and stored whenever the instrument is powered up or reset.

You should therefore make sure that power up takes place under clean air conditions.

ATTENTION: The fuse (T1A) is at mains voltage. All works on it are to be carried out by qualified

personnel only, observing appropriate precautions!
