4.13 External Rain Gauge
Models without integrated precipitation acquisition can be equipped with an external rain
gauge.
External rain gauge and external temperature sensor can not be connected at the same
time.
4.14 (WS100-UMB only: ) Impulse Output for Rain Gauge Simulation
WS100-UMB provides a digital impulse output for simulation of a rain gauge. Depending on
configuration settings the output is pulsed once for each 1.0mm, 0.5mm, 0.2mm, 0.1mm or
0.01mm (default) of precipitation.
If the WS100-UMB is configured for impulse output, the serial interface is not available for
communication in UMB or other serial protocols.
