Fig. 11: Parameter adjustment example min./max. adjustment
1 Min. level = max. measuring distance
2 Max. level = min. measuring distance
3 Reference plane
If these values are not known, an adjustment with the distances of e.g.
10 % and 90 % is possible. Starting point for these distance specifica-
tions is always the sealing surface of the thread or flange. You can find
specifications on the reference plane in chapter "
Technical data
". The
actual level is calculated on the basis of these settings.
The actual product level during this adjustment is not important,
because the min./max. adjustment is always carried out without
changing the product level. These settings can be made ahead of
time without the instrument having to be installed.
The function "
Setup
" allows the echo curve to be saved at the time of
setup.
Information:
This is generally recommended, however, for use of the Asset
Management functions it is absolutely necessary. Saving should be
carried out with a very low level.
The function "
Echo curve memory
" allows up to ten individual echo
curves to be stored, for example to detect the measurement behav-
iour of the sensor in different operating conditions.
With the adjustment software PACTware and the PC, the stored echo
curves can be displayed with high resolution and used to recognize
signal changes over time. In addition, the echo curve saved during
setup can also be displayed in the echo curve window and compared
with the current echo curve.
