In the case of a linear dependency, the calibration function is determined by
means of linear regression. The slope and axis intercept (E0) are the charac-
teristics of the calibration line.
In the case of a nonlinear dependency, the points of the measuring ranges
can be connected to each other as a polygon line or approximated as a
parabola:
