3 C onfirm "False signal suppression - Change now" with [OK] and
select in the below menu "Create new". Enter the actual distance
from the sensor to the product surface. All false signals in this area
are detected by the sensor and saved after confirming with [OK].
Note:
C
heck the distance to the product surface, because if an incorrect (too
large) value is entered, the existing level will be saved as false signal.
T
he filling level would then no longer be detectable in this area.
T he menu item "Extended setting" offers the possibility to optimise
VEGAPULS 68 for applications in which the level changes very
quickly. For this reason, select the function "Quick level change > 1 m/
min.".
E xtended setting
quick level change > 1 m/min.
Note:
S
ince with the function "Quick level change > 1 m/min." the generation
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 echo memory is thus recom-
mended.
T his function enables reading out parameter adjustment data as well
as writing parameter adjustment data into the sensor via the indicating
and adjustment module. A description of the function is available in the
operating instructions manual "Indicating and adjustment module".
T he following data are read out or written with this function:
l M easured value presentation
l A djustment
l M edium
l I nner diameter of the standpipe (with standpipe versions)
l V essel form
l D amping
l L inearisation curve
l S ensor-TAG
l D isplayed value
l D isplay unit
l S caling
l C urrent output
l U nit of measurement
l L anguage
T he following safety-relevant data are not read out or written:
l HART mode
l PIN
