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.

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.
