DEAD ZONE
In connection with the measurement principle, the signals reflected in the area
just under the level meter can-
not be evaluated. The zone (Fig. 3 and 4) determines the min. distance possible between the level meter and
the highest surface level. It is necessary to install the level meter so that the bin level cannot interfere with the
dead zone when filled up to the maximum or deplete to the minimum. If the measured level interferes with the
dead zone, the level meter will not work properly.
The size of the dead zone is affected by the set measurement sensitivity. The minimum distan
c
es to the medi-
um (dead zones) are presented in the tables below.

INPUT NECK
For correct measurement
it is important to avoid installation in
the high
neck. For short neck are reco
mmended next condi-
tions: a < b, b > 50 mm, where a is the neck height and b is the
n
eck width
If you can not eliminate all interference, which could affect
the measurement of level, it is recommended to use the
procedure "TEACHING" (see chap. 10.2 Service settings).
This procedure sets the level meter to mode, which sup-
presses false reflections.
