Note!
1. For this level mode, the measured variables "height + %", "height + volume", "height + mass",
"%-height + %", "%-height + volume" and "%-height + mass" are available.
→ ä 166 ff.
2. You can also specify customer-specific units. See parameter descriptions for PRESS. ENG.
UNIT (060) (→ ä 155), HEIGHT UNIT (708) (→ ä 170), UNIT VOLUME (313) (→ ä 171)
and MASS UNIT (709) (→ ä 172).
3. Once you have entered the maximum level to be expected for LEVEL MAX., the alarm "A707
X-Val of lin. table out of edit limits" can appear. At this stage, the linearization table already
consists of two points as standard. It could be the case that the 2nd value, and thus the highest
X-VALUE of the linearization table, is greater than the maximum level entered. The message
disappears as soon as the highest X-VALUE is greater than the maximum level and the table
entered is active.
4. You can use the MENU DESCRIPTOR (416) parameter (→ ä 194) to specify which measured
value should be displayed on the local operation.
20 Select the "Editor table" option by means of the TABLE
SELECTION parameter.

5 See Table, Step 18.
6 See Table, Step 19.
7 See Table, Steps 20 to 24.
21 Select the "Semiautomatic" option by means of the LIN.
EDIT MODE parameter.
22 Select the "New table" option by means of the EDITOR
TABLE parameter.
23 Enter the linearization table (min. 2 points, max.
32 points).
Fill the tank to the height of the 1st point.
LINE-NUMB: Confirm value displayed.
X-VAL.: The hydrostatic pressure present is measured
and converted to the corresponding level and displayed.
The X-VAL. displayed is saved by confirming the Y-
value. See following line, Y-VAL.
Y-VAL.: Enter the volume value, here 0 m
3
for example,
and confirm the value.
24 Local operation
If you want to enter another point for the linearization
table, select the "Next point" option and enter the point
as described in Step 23. If you want to finish entering the
values and activate the linearization table, select the
"Accept input table" option.
FieldCare:
You can enter further points for the linearization table as
explained in Step 23. Once all the points have been
entered, the table must be activated by means of the
TAB. ACTIVATE parameter.
25 Result:
– The linearization table has been entered.
– The measured value display and the
TANK CONTENT parameter display the 2nd
measured value (here the volume).
– The LEVEL BEFORE LIN parameter displays the 1st
measured value (here the height). See also Point 5 in
the following note.
