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.
Before entering a linearization table, the values for
and
Full calibration (→ 138)
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
