18.5 Cleaning and maintenance
Vane anemometers are precision products which will give fault-free service if correctly handled. If you handle them
as described in the operating instructions, your instruments and probes will remain in a serviceable condition and
ensure the reliable operation of the measuring system. Each instrument has its designed range of application and is
only to be used for this range.
If faults should nevertheless occur, do not attempt to open the instrument and repair it yourself; always have
repairs carried out by our after-sales service.
