Nonlinear error compensation (NLEC)
For Nonlinear error compensation (NLEC) the measuring range is divided into a
grid by defining up to 99 supporting points. For each of the identically-sized surface
segments a specific compensation factor is determined by comparing nominal and
actual values (the measured values).
The following options are available for measuring the nominal and actual values of
the supporting points:
Create the table of supporting points manually and enter actual values
Create the table of supporting points manually and determine actual values in a
teach sequence
Read deviations of the calibration standard and enter actual values, determine
these in a teach sequence or import the values (.txt)
Import formats:
.txt format: contains actual values of the supporting points
Extended .txt format: contains deviations of the theoretical nominal value
Import a table of supporting points with nominal and actual values (.xml)
Import format
.xml format: corresponds to the standard export format of the product

If you read the deviations of a calibration standard or import a table of
supporting points and the number or distances of the supporting points
are different from the existing table of supporting points, a new table of
supporting points is generated. The original table of supporting points is
overwritten.
