4. MAINTENANCE
Except for the batteries, the instrument contains
no parts that can be replaced by personnel who have not
been specially trained and accredited. Any unauthorized
repair or replacement of a part by an “equivalent” may
gravely impair safety.
4.1. CLEANING
Disconnect the instrument completely.
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.
4.2. REPLACEMENT OF BATTERIES
If, during the self-test, only half of the indicators light, you
must replace the batteries.
Disconnect anything connected to the device.
Using a screwdriver, unscrew the two captive screws of
the battery compartment cover located on the back of
the device.
Withdraw the spent batteries and replace them with two
new batteries (AAA or LR3 1.5V alkaline batteries).
Close the battery compartment cover and make sure that
it is completely and correctly closed.
Screw the two screws back in.
Spent batteries must not be treated as ordinary
household waste. Take them to the appropriate
recycling collection point.
4.3. METROLOGICAL CHECk
Like all measuring or testing devices, the instrument
must be checked regularly.
This instrument should be checked at least once a year.
For checking and calibration, contact one of our accredited
metrology laboratories (information and contact details
available on request), at our Chauvin Arnoux subsidiary or
the branch in your country.
4.4. REPAIR
For all repairs before or after expiry of warranty, please return
the device to your distributor.
