Note: This measurement indicates the accumulated precipitation quantity since the last
device reboot. The measurement is retained for the duration of a short power failure (up to
15 minutes). To reset this value, use the corresponding function in the UMB-Config-Tool
(see page 30) or disconnect the device from the power supply for at least one hour.
6.13 Precipitation Quantity - Differential
Sampling rate Event-dependent on reaching the response threshold
Response threshold 0.01mm
Units l/m²; mm; in; mil
Request channels:
Measurement Variable (float)
Precipitation Quantity - Differential

Note: Each request from a differential channel sets the accumulated quantity back to zero. If
the response from the device is lost due to a transmission error (e.g. poor GPRS
connection), the quantity accumulated to date is also lost. The quantity accumulated to date
is also reset each time the equipment is rebooted.
6.14 Precipitation Intensity
Sampling rate 1 minute
Response threshold 0.6 mm/h
Units l/m²/h; mm/h; in/h; mil/h
Request channels:
Measurement Variable (float)
Note: The precipitation intensity is always calculated on the basis of the precipitation
intensity of the previous minute.
