Maintenance, care and adjustment
The combination sensor will need to be cleaned from time to time to remove the dirt
that will accumulate on it. When you do this, you should also check that the wind
sensors can move easily and that the sensors are properly seated on their supports.
7.1
Cleaning the rain sensor
• Depending on the location, leaves, dirt particles transported by the wind,
sand, branches, etc., may get into the rain sensor’s collecting funnel. Larger
items may block the flow of rainwater. Sand can also accumulate in the
counter rocker: as the amount increases, this causes the measurement
results to be less accurate.
• Consequently, the rain sensor must be cleaned from time to time; this must
be done at least once a year, however. The images below provide a guide to
disassembly and reassembly.
• The sensor housing can be detached for cleaning purposes by turning it
slightly anticlockwise.
• The collecting funnel can also be detached by turning it anticlockwise.
