15. Cleaning and care
The function of the DuoFern Sun/Wind Sensor can be affected by envi-
ronmental influences:
◆
For example, dust or bird droppings on the top of the
housing can impair the solar cell and obscure the light sensor.
◆
A dirty wind propeller will no longer turn smoothly
and may result in incorrect measurement results.
For the safe operation of the DuoFern Sun/Wind Sensor, it is important
that it remains as clean as possible and that the wind propeller can be
moved easily:
◆
Clean the DuoFern Sun/Wind Sensor regularly with a mild soapy
solution.
◆
Check the wind propeller regularly to ensure it moves easily.
◆
Carry out a regular function test for the sun and wind function,
