To adjust the angle of inclination with the swivelling holder see next
section.
Proceed as follows to align the sensor with the swivelling holder:
1. Loosen terminal screw of the swivelling holder with a fork spanner

Information:
The hexagon screws must not be loosened.
2. Align the sensor, check angle of inclination. Max. angle of inclina-
tion of the swivelling holder see chapter "

The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the radar signals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
