11.5.1 Special Case of Precipitation
Except for the amount of precipitation, all measured values are to be read in as instantaneous values. The amount
of precipitation must be read in as a total amount. And the difference to the previous call must be formed for the
displayed and the precipitation quantity to be stored.
Note: The value overflow of the precipitation sum must be considered when calculating the difference.
The value overflow occurs at 60,000 g of collected liquid. This results in a value overflow at 3,000 mm for
sensors with a collecting surface of 200 cm
2
and a value overflow at 1,500 mm for sensors with a collecting
surface of 400 cm
