7. Maintenance and calibration
The weather protection shields are maintenance-free to the greatest possible extent. The mean life
expectancy of the fans is 70.000 hours at ambient conditions (40 °C). This equals to ca. eight
years.
We recommend calibrating the probes once per year. Hints regarding the calibration may be found
in the manuals accompanying the probes.
8. Spare Parts
The weather protection shields are maintenance-free to the greatest possible extent. They do not –
with the exception of the fans- contain wear parts.
The probes are equipped with filters, which should be replaced periodically. The point in time for
their replacement is mainly determined by the prevailing ambient conditions. Therefore, a
recommendation regarding the replacement interval cannot be given. However, we recommend
calibrating respectively adjusting of the probes at least once per year. This is a good opportunity to
replace the filters. These may be cleaned in soapy water. The use of ultrasonic cleaners is also
possible.
