Example:
In a vessel 20 m high, the installation position of the sensor is 1.4 m
from the vessel centre.
The necessary angle of inclination of 4° can be read out from this
table.
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 "

3. Re-tighten the terminal screw, max. torque 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.
