SENSITIVITY
The setting is defined in three steps of the level meter sensitivity.
"LOW"
– Low sensitivity in case of surrounding interferences affecting the measurement.
"MEDIUM" – Medium sensitivity (suitable for most applications).
"HIGH"
– Enhanced sensitivity for measured mediums partly absorbing the ultrasonic signal (bulk solids, foams)

TEACHING
The mode serves for suppressing false reflections resulting from reflection of the ultrasonic
signal from roughnesses on walls of the tank, various partitions, mixers or other obstacles. The
sensor starting this mode detects false reflections and save them in the memory. Then these false
reflections will not affect the subsequent measurement (they are masked).
Before starting the mode it is necessary to empty the tank as much as possible (prefer-
ably completely).

distance to the level is not precisely known, enter a value lower (in the tolerance field as
shown in Fig. 19).

After entering the "SET LEVEL DISTANCE" by pressing
(false reflection mapping). During the mapping, the display shows fl shing sign "RUNNING".

The mapping of false echoes can be completed when you see the inscription "Press OK to stop"
and you press

5. The procedure is completely finished when you can see the inscription "DONE". It is then
possible to exit the menu by repeated pressing the button

If during the scanning of the tank in the bottom of the display appears
the dialog "press OK to stop" (see figure) the level meter already found
no further obstacles and "TEACHING" mode may be terminated. If it is
not terminated, the level meter is still ready for the possible presence
of obstacles (e.g. paddles of the agitator). Once it registers a further
obstacle, the dialogue disappears and the obstacle is erased. This
process may be repeated up to 1000 cycles. After this the "TEACHING" mode is automatically stopped.
