Additional information Meaning of the options
• Manual
The level and the associated linearized value are entered manually for each
linearization point.
• Semi-automatic
The level is measured by the device for each linearization point. The associated
linearized value is entered manually.
• Clear table
Deletes the existing linearization table.
• Sort table
Rearranges the linearization points into an ascending order.
Conditions the linearization table must meet:
• The table may consist of up to 32 pairs of values "Level - Linearized Value".
• The table must be monotonic (monotonically increasing or decreasing).
• The first linearization point must refer to the minimum level.
• The last linearization point must refer to the maximum level.
Note: Before entering a linearization table, the values for Empty calibration
(page 102) and Full calibration (page 102) must be set correctly. If values of the
table need to be changed after the full or empty calibration have been changed, a
correct evaluation is only ensured if the existing table is deleted and the complete
table is entered again. To do so delete the existing table ( Table mode = Clear
table ). Then enter a new table.
How to enter the table
• Via PACTware
The table points can be entered via the Table number (page 122), Level
(page 122) and Customer value (page 122) parameters. As an alternative, the
graphic table editor may be used: Device Operation  Device Functions 
Additional Functions  Linearization (Online/Offline)
• Via local display
Select the Edit table (page 124) submenu to call up the graphic table editor.
The table is displayed and can be edited line by line.
Note: The factory setting for the level unit is "%". If you want to enter the
linearization table in physical units, you must select the appropriate unit in the Level
unit parameter (page 114) beforehand.
