Formula

Customer-specific linearization is specified using a 4th order polynomial. The polynomial is cal-
culated for the entire linearization range.
Polynomial formula: y = X4*x

The co-domain of the linearization (linearized values, y-axis) is checked in the module and
limited as follows:
Co-domain lower limit = Ymin - 0.0125 × (Ymax - Ymin)
Co-domain upper limit = Ymax + 0.03125 × (Ymax - Ymin)
