False signal suppression
Change now?
Proceed as follows:
1. Move from the measured value display to the main menu by
pushing [OK] .
2. Select the menu item " Service " with [->] and confirm with [OK] .
Now the menu item " False signal suppression " is displayed.
3. Confirm " False signal suppression - Change now " with [OK] and
select in the below menu " Create new ". Enter the actual distance
from the sensor to the medium surface. All false signals in this
area are detected by the sensor and saved after confirming with
[OK] .
Note:
Check the distance to the medium surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
signal. The level would then no longer be detectable in this area.
The menu item " Extended setting " offers the possibility to optimise
OPTISOUND 3010 C for applications in which the level changes very
quickly. To do this, select the function " Quick level change > 1 m/
min. ".
Extended setting
quick level change > 1 m/min.
Note:
Since with the function " Quick level change > 1 m/min. " the genera-
tion of an average value of the signal processing is considerably
reduced, false reflections by agitators or vessel installations can
cause measured value fluctuations. A false signal suppression is thus
recommended.
In the menu item " Current output " you determine the behaviour of the
current output during operation and in case of failure. The following
options are available:
