10.2.7 Precipitation Sensor Settings (Radar)
Heater mode: The device can be configured for heating in different operating modes.
Configure as ‘automatic’ in normal operating mode. You can find a precise
description of the operating modes on page 39.
Followup time precipitation type: for this time (in seconds) the detected precipitation type is
shown; to cover all events, this time must be adjusted to the poll rate.
Note:
All other parameters, especially those in the ‘Rainfall calibration data’ tab‚ may only be
changed after consultation with the manufacturer, as they have a major influence on the
functioning and accuracy of the sensor.
10.2.8 Precipitation Sensor Settings (Rain Gauge)
The rain gauge module can be operated with resolutions 0.2mm or 0.5mm. The setting of the
resolution is to be done in two steps:
Mechanical setting
Configuration setting
The mechanical setting works by modifying the effective area of the funnel. The sensor is
delivered with a reduction ring, which can be mounted on the funnel to reduce the area.
Funnel with reduction ring
resolution 0.5mm
Funnel without reduction ring
resolution 0.2mm
Then the resolution is set in the sensor configuration using the UMB Config Tool.
Caution:
If mechanical setting and configuration setting do not conform, the sensor will
deliver wrong precipitation values!
