the charging contacts become very dirty, clean them carefully.
Dirt and deposits can be removed from the instrument by washing

it with cold water. A sponge can be used for wiping if necessary.
CAUTION
!
Rough cleaning equipment (brushes, etc.), cleaning agents
and solvents may destroy the dust and water filter and could
result in incorrect measurement results.
If necessary, replace the membrane positioned in front of the sensors,

in accordance with national regulations.
Inspection by suitably qualified persons – every sjx months.

- The inspection intervals must be established in each individual
case and shortened if necessary, depending on technical safety
considerations, engineering conditions, and the technical
requirements of the equipment.
