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.
Proceed as follows:
1. Select the menu item "Setup" with [->] and confirm with [OK].
Now select with [->] the menu item "Min. adjustment" and confirm
with [OK].
2. Edit the percentage value with [OK] and set the cursor to the
requested position with [->].
3. Set the requested percentage value with [+] and save with [OK].
The cursor jumps now to the distance value.
4. Enter the suitable distance value in m for the empty vessel (e.g.
distance from the sensor to the vessel bottom) corresponding to
the percentage value.
5. Save settings with [OK] and move with [ESC] and [->] to the max.
adjustment.
Proceed as follows:
1. Select with [->] the menu item Max. adjustment and confirm with
[OK].
2. Prepare the percentage value for editing with [OK] and set the
cursor to the requested position with [->].
