Parity: even
Stop bits: 1
The following communication settings apply to the Modbus protocol.
Baud rate:
19200 baud
Data bits: 8
Parity: even
Stop bits: 1
Other protocols can also be selected but these do not support the output of precipitation type. For further details
see the section Protocols of the rain[e]observer .
The changes to the output protocol are in accordance with the section

13.4 Closing the housing
1. Connect the clamping plug of the heating and position the upper housing section in such a way that the open/
close sticker sits over the knurled screw.
2. Press the housing down and turn it clockwise in the direction of close.
3. Tighten the knurled screw.
14 Checking and troubleshooting
• Visual inspections for contamination should be carried out regularly - depending on the environment and
seasonal influences (spider and bird populations, pollen, foliage, etc.). In accordance with section 6 of the
VDI guidelines - environmental meteorology - meteorological measurements - precipitation, VDI 3786 part 7
(December 2010) , monthly inspections are recommended. In areas with high air pollution levels, weekly
inspections may be necessary in order to ensure correct measurement results.
Please disconnect all external cables before you clean the inside of the sensor in order to
avoid incorrect measurements. The funnel heating and drainage heating may get very hot
if the heating is operated with the housing open. There is a risk of burns. It is therefore
recommended that you unplug the heating supply connector when doing any cleaning or
maintenance work.
• All parts exposed to water should be cleaned regularly. Rinsing with clean water should be enough to remove
most of the dirt. Any dirt stuck in the collecting funnel or drainage system must be carefully removed. Slight
soiling of the collecting container is not critical. The collecting container can be cleaned with water and a mild
detergent.
• Make sure the device is stable and upright and check the bird deterrent ring, the sensor and especially the
funnel surface for damage.
• Keep the measuring site free of overgrowing bushes and trees.
• The bird deterrent ring must be removed during periods of frost and snow.
Care should be taken when cleaning the collecting container in order to avoid damage. Do
not clean the Rain[e] and the collecting container with a steel brush or similar devices or with
aggressive cleaning agents.
