7.1 Maintenance
These gas density monitors are maintenance-free.
The indicator and switching function should be checked once or twice every year. For
this the instrument must be disconnected from the gas compartment to check with a
pressure testing device (e.g. WIKA BCS-10).
Repairs must only be carried out by the manufacturer.
The instruments must not be opened, since this can lead to indication and switch point
errors.
