Voltage analog output (optional):
By default, the voltage analog output is 0…10 V, with:
0 V = sensor sensitive surface completely wet
10 V = sensor sensitive surface completely dry
With the commands of the proprietary protocol it is possible to set the range 2…10 V
for the output and reverse the direction of the output, so that when the sensor sensi-
tive surface is completely wet the output is 10 V.
In case of measurement error, the output goes to 11 V.

Contact output:
There is a normally open voltage-free contact between pins 1 and 4 of the connector
(green and blue wires of the optional CP2013.2… cable). The contact closes when the
sensor detects a precipitation in progress.
