7.1 Adjustment with medium
You can either carry out the adjustment with
medium or without medium. To carry out an
adjustment with medium, it is necessary that
you know the percentage values of the ves-
sel for the actual filling.
For this procedure, percentage values must
be entered for min. and max. values that
correspond to the actual fillings. The se-
quence of the min. or max. value is not impor-
tant. For example, if you know that your filling
is presently 80 %, you can enter in the menu
item Max. adjustment the value "80“. Then if
your filling is, for example, 10 %, you enter in
the menu item Min. adjustment the value "10“.
The larger the difference between the two
adjustment points, the more exact the meas-
urement over the whole measuring curve. It
would be ideal if the adjustment could be
carried out at 0 % and 100 %. For practical
reasons, however, it is not always possible to
completely fill or empty a vessel. The dis-
tance between the two adjustment points
however, should be at least 10 % of the sen-
sor range.

Adjustment example
You know that your vessel is pres-
ently filled up to 80%. Move to the
menu item "Max-adjust at % 100.0“.
Briefly push the [–] key, so that the
figure 100.0 flashes (editing mode).
Continue pushing [–] until the figure
80.0 appears on the display. Now
push [OK] to save the adjustment.
Then, if your filling is for example
10 %, move to the menu item "Min-
adjust at % 0.0“. Briefly push the [+]
key until the figure 0,0 flashes (edit-
ing mode).
Continue pushing [+] until "10“ ap-
pears on the display. Now push [OK]
to save the adjustment.
Of course, you can carry out the adjustment
with medium also at 0 % and 100 % filling.
Please note: The figures 0 % and 100 % must
flash (editing mode) before they can be
saved with the [OK] key.
Note:
If the medium is later changed (medium with
another density value or dielectric constant)
and no new adjustment is possible or when
the MET indication and the DIS outputs refer
to height in metres, note the following: For
applications with hydrostatic pressure trans-
mitters, the adjusted density value must
correspond to the value of the medium.
The menu item "Density…“ is displayed if the
appropriate sensor type was selected under
"Configuration measurement loop“.
