4. MAINTENANCE

Any unauthorized repair or replacement of a part

by an “equivalent” may gravely impair safety.

4.1. CLEANING

Disconnect everything connected to the instrument and

switch it off.

Use a soft cloth, dampened with soapy water. Rinse with a

damp cloth and dry rapidly with a dry cloth or forced air. Do

not use alcohol, solvents, or hydrocarbons.

Make sure that no foreign body interferes with the operation

of the snap device of the sensor.

4.2. REPLACEMENT OF THE BATTERIES

The battery must be replaced when the green indicator

ﬂashes or remains off when the instrument is switched on.

 Disconnect everything connected to the instrument and

and switch it off.

 Use a screwdriver to unscrew the two closing screws of

the housing.

 Replace the old battery with a new battery (1.5 V R03 or

AAA super‑alkaline batteries).

 Close the housing; make sure that it is completely and

correctly closed.

 Screw both screws back in.

Spent batteries must not be treated as ordinary

household waste. Take them to the appropriate

recycling collection point.
