5 Maintenance, cleaning, disposal
5.1 Maintenance
The meter is almost maintenance-free.
The only maintenance activity is exchanging the battery when it is depleted
(LoBat display indicator).
5.2 Battery exchange
The LoBat display indicator indicates that the battery should be changed. The
battery is then largely depleted.
Caution
Only use leakproof alkaline manganese batteries.
Replacing the
battery
1 Unscrew the screw (1) on the back of the meter and remove the lid
of the battery compartment by pulling at the screw.
2 Remove the depleted battery from the battery compartment.
3 Place the new battery (type Mignon AA) in the battery compartment.
Make sure that the poles of the battery are the right way round. The
± signs on the battery must correspond to the ± signs in the battery
compartment.
4 Close the battery compartment.
