Maintenance, cleaning
The meter is almost maintenance-free.
The only maintenance task is replacing the batteries or rechargeable
battery.
NOTE
Make sure the poles of the batteries are the right way round. The ±
signs on the batteries must correspond to the ± signs in the battery
compartment.
1
Open the battery compartment:
– Unscrew the two screws (1) on the underside of the meter,
– Remove the lid of the battery compartment (2).
2
If necessary, take four old batteries out of the battery
compartment.
3
Insert four batteries (3) in the battery compartment.
4
Close the battery compartment and fix it with the screws.
Dispose of used batteries according to the local regulations of your
country.
End users within the European Union are obligated to return used bat-
teries (even ecologically compatible ones) to a collection point set up
for recycling purposes.
Batteries are marked with the crossed-out waste container symbol.
Therefore, they may not be disposed with the domestic waste.
Occasionally wipe the outside of the meter with a damp, lint-free cloth.
Disinfect the housing with isopropanol as required.

The housing components are made out of synthetic materials
