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.
• The lower range value (= 4 mA) is defined by the smallest point in the table.
The upper range value (= 20 mA) 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.
9.11.2 Manual entry of a linearization table
Example:
In this example, the volume in a tank with a conical outlet should be measured in m 3 .
Prerequisite:
• This is a theoretical calibration, i.e. the points for the linearization table are known.
• The "Level" measuring mode has been selected.
• A level calibration has been performed.
• The linearization characteristic must rise or fall continuously.
• For a description of the parameters mentioned, see the "Description of device
parameters" section →  88.

WARNING
Changing the measuring mode affects the span (URV)
This situation can result in product overflow.
‣
If the measuring mode is changed, the setting for the span (URV) must be checked in
the "Setup" operating menu and readjusted if necessary.
