Description
3 Enter the number of the point in the table
using the "Line-numb" 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-val" parameter,
here 0 m for example. Confirm your entry.
Menu path: Setup → Extended setup →
Linearization → X-val
Enter the associated volume value via the "Y-
val" parameter, here 0 m
3
for example, and
confirm value.
Menu path: Setup → Extended setup →
Linearization → Y-val
4 To enter another point in the table, select the
"Next point" option via the "Edit table"
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" 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 largest 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.
9.13 Manual entry of a linearization table via operating
tool
The following options are available to you with an operating tool that is based on FDT
technology (e.g. FieldCare), you can enter linearization using a module specially designed
for this purpose. 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).
