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.
• 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.
