5 Installation
Attention:
The instrument must be mounted and wired only by a qualified
expert, who knows and observes the generalities of technics, and
applicable regulations and norms.
Attention:
Do not look into the invisible laser beam!
In case the laser caution labels on the housing are not legible any
more the sensor must not be operated!
Even with a longer exposure time the intensity of the invisible laser
beam is considered as safe for the human eye (without using optical
instruments).
A skin-contact with the invisible radiation is, in general, harmless.
Attention:
Head and carrier heatings could be hazardous hot! Burn Hazard!

5.1 Suggestions for Mounting Place
Please note the following when selecting the location:
The sub-surface under the Laser Precipitation Monitor shall not consist of dark stone, asphalt or the
like, as otherwise, in case of strong sunshine radiation, the ascending air will form so-called
streaks. As sub-surface we recommend a lawn.
Depending on the wind speed and wind direction the precipitation particles are swirled by the Laser
Precipitation Monitor so that the fall speed is changed. This might cause a deterioration of the
sensor quality. Therefore, you should avoid an installation in the open country (particularly
mountain tops) or directly in the lee of an obstacle. Well-suited are flat locations with wind breaks
(e.g. hedges).

According to the WMO-directive for precipitation measuring instruments the distance between the
installed sensors and the next obstacle should be at least four times the height of this obstacle.
If this is not practicable, at least keep an azimuth angle of < 45° with regard to the surrounding
plants, buildings etc. Logically consistent would be also to mount the sensor on a mast top. We
recommend a measuring height of at least 1m or rather 1.5 to 2m in snowy sites. Other devices
