2.3.3 Rainfall measuring system S 2010 R
The rainfall measuring system is also solar powered and is provided with a fixed
address which cannot be manipulated by the user. The solar cell must be accurate-
ly aligned to face south.
The rainfall measuring system must be positioned on an absolutely horizontal sur-
face and fixed by means of screws inserted in the holes in the base of the housing.
Remove the upper section be-
forehand by pressing it and
turning clockwise. There is a re-
cess in the lower section which,
when filled with water, provides
a perfectly horizontal alignment
without any other resources re-
quired. Fill the recess with a litt-
le water and then align the lower
part of the housing according to
the spirit level principle. After
marking the installation position
exactly, drain off the water. En-
sure the solar cell faces south.
The short side of the integrated
spirit level must point north (re-
fer to diagram).
To enable good transmission
(wide range), it is better not to set
the rainfall transmitter directly on
the ground. Installing it approx.
1 m above ground level produ-
ces the best results and protects
the system from dirt (especially
