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.
11.8.2 Manual entry of a linearization table via operating tool
Using an operating tool 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 (menu "Device Operation"
®
"Device Functions"
®
"Additional Functions"
®
"Linearization Table".
The linearization table may also be entered manually point by point in the operating tool menu
(see (
