6.20 Drop Diameter Distribution (WS100 only)
Drop diameters of precipitation detected by the radar sensor are shown as distribution of
drop diameter classes. Diameters are calculated as volume equivalent ball diameter.

Note: Similar to the request of differential precipitation quantity the accumulated sum of
events of each channel will be reset to 0 after transmission!
For consistent results all related channels should be requested in one run.
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.
