Maintenance and cleaning
To prevent electric shocks, do not allow moisture to ingress the housing.
| Use a dry cloth, without cleaning agent, to clean the housing at regular intervals. Do not use
any abrasive or scouring agents, or solvents.
Replacing the battery
To open the battery compartment on the bottom of the instrument, undo the Phillips screw with
a Phillips screwdriver size 1. The lid can now be opened and the AA batteries replaced.
If the instrument is not going to be used for a long period of time, the batteries should be removed
and the tester kept in an environment that is not too humid or too hot.
Do not leave any spent batteries in the measurement instrument, because even leak-proof
batteries can corrode and, as a result, release chemicals that could damage your health and
destroy the instrument.
Batteries must not be disposed of with normal domestic waste. There will be a
collection point near you!
