Depending on the location, leaves, particles of dirt carried by the wind, small twigs and similar can enter the
cone collector of the rain gauge. Large parts can clog the flow-through!
Sand can also collect in the count rocker which will affect the measuring result negatively as it increases.
For this reason, the rain gauge should be cleaned at least once a year.
Proceed as follows:
• open the lower part of the rain gauge. To do this, turn the lower part approx. 1 cm to the left until you can
let the metal nips slide downwards.
• remove the upper cone collector by turning it first of all a small distance to the right; then lift it off to the
top.
• the rainfall sensor (the plastic part with the two brass pins and cable) can now be removed.
Make a note of the orientation; the connection cable of the rainfall sensor can be found at one side.
• Remove the count rocker.
Make a note of the orientation; there is a small magnet at one side of the count rocker.
• Now clean the components of the rain gauge. Think also of the drain hole in the plastic lower part of the
rain gauge which you have pushed downwards at the metal pipe.
• To reassemble, place the count rocker first of all in the
holder.
For this, the magnet of the count rocker has to belo-
cated on the side which points to the cable.
The two lower trapezoid pins have to be inserted into
the lower part of the holder correctly.
Only in this manner is it guaranteed that the count
rocker can be moved easily.
