Maintenance
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.
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.
Cleaning
Occasionally wipe the outside of the meter with a damp, lint-free cloth.
Disinfect the housing with isopropanol as required.
NOTE
The housing components are made out of synthetic materials
