Measured value max.
To damp process-dependent measured value fluctuations, you can
set a time of 0 … 999 s in this menu item.
The default setting is a damping of 0 s.
In this menu item you can adjust the damping of the sensor. With
it you can suppress fluctuations in the measured value indication,
caused e.g. by an agitated product surface. This time can be between
1 and 1200 seconds. Keep in mind that the reaction time also in-
creases and the instrument reacts to quick level changes with a delay.
Generally a time of approximately 60 seconds is sufficient to smooth
the measured value indication.
With the setting "Automatic", the instrument itself calculates a suitable
damping on the basis of the adjustment and the measured value
changes. This setting is particularly suitable for application where fast
and slow level changes occur.
The implementation of a real value corretion is only necessary if the
requirements of the measurement loop have changed, for example
with abrasion in a tube.
If you know the density of a certain medium, you can enter the deter-
mined real density in this menu item to correct the measured value.
The function shifts the linearization curve to this determined point.
The measurement can thus be adapted exactly to the conditions in
the tube.
