Precipitation Type
0 = No precipitation
60 = Liquid precipitation, e.g. rain
70 = Solid precipitation, e.g. snow
40 = unspecified precipitation
(WS401-UMB, WS601-UMB, external
rain gauge)
Note:
A detected precipitation type remains valid for 2 minutes after the end of the
precipitation event. In order to record precipitation types which only occur for a short period
(e.g. short-term rain), the request interval should be 1 minute or shorter.
Ice, hail and sleet are transmitted as rain (60).
The versions WS401-UMB and WS601-UMB as well as the external rain gauge do not
include detection of precipitation type, so in this case only type 40 (unspecified precipitation)
is indicated. Due to the function of the rain gauge only liquid or molten precipitation can be
recognized.

When operated in Power Saving Mode 1 (see page 37) the WS700-UMB will measure the
global radiation only once per minute.
