7.1.2 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

+ X3*x

+ X2*x

+ X1*x + X0

Setup dialog

Parameter

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)

Parameter Selection/settings Description

X0 -99999 to 0 to +99999 Absolute component of the polynomial

(point of intersection with the y-axis)

X1 -99999 to 1 to +99999 Coefficient of the linear component (x)
