Description
3 Enter the number of the point in the table
using the "Line number (039)" parameter e.g. 1.
Menu path: Setup → Extended setup →
Linearization → Line numb.

h Height
i Current value
v Volume
The level is entered via the "X-value (040)"
parameter, here 0 m for example. Confirm your
entry.
Menu path: Setup → Extended setup →
Linearization → X-value
Using the "Y-val. (041)" parameter, enter the
corresponding volume value, here 0 m
3
for
example, and confirm the value.
Menu path: Setup → Extended setup →
Linearization → Y-value
4 To enter another point in the table, select the
"Next point" option via the "Edit table (042)"
parameter. Enter the next point as explained in
Step 3.
Menu path: Setup → Extended setup →
Linearization → Edit table
5 Once all the points have been entered in the
table, select the "Activate table" option via the
"Lin. mode (037)" parameter.
Menu path: Setup → Extended setup →
Linearization → Lin. mode
6 Result:
Result: The measured value after linearization
is displayed.
• Error message F510 "Linearization" and alarm current as long as the table is being
entered and until the table is activated.
• Error message F511/F512 "Linearization" and alarm current as long as the
linearization table consists of fewer than 2 points.
• The lower range value (= 4mA) is defined by the smallest point in the table.
The upper range value (= 20mA) is defined by the greatest point in the table.
• Using the parameters "Set LRV" and "Set URV", you can change the allocation of the
volume/mass values to the current values.
9.11.2 Manual entry of a linearization table via operating tool
With an operating tool based on FDT technology (e.g. FieldCare), it is possible to enter
linearization via a module that has been specially designed for this. This provides you with
an overview of the selected linearization, even during entry. In addition, it is possible to
configure different tank shapes in FieldCare ("Device operation" → "Device functions" →
"Additional functions" → "Linearization table" menu).
The linearization table may also be entered manually point by point in the operating
tool menu (see section →  78).
9.11.3 Semi-automatic entry of a linearization table
Example:
In this example, the volume in a tank with a conical outlet should be measured in m
