Rys. 10. Individual Characteristic.
During the function approximation, one must remember that for the ap-
proximation of functions strongly differing from the linear characteristic,
higher the number of linearizing segments, smaller the error related to
the linearization.
If measured values are smaller than H1, recalculations will be made
on the base of the first straight line calculated on the base of points
(H1,Y1) an (H2,Y2). However, for values higher than Hn (where n – the
last declared measured value) the value to display will be calculated
on the base of the last assigned linear function.
Note: All introduced points of the measured value (Hn) must be arran-
smaller than the number of points. Next, one must program successive
points by giving the measured value (Hn) and the expected value cor-
responding to it, – value which has to be displayed (Yn). The graphic in-
terpretation of the individual characteristic is presented on the fig. 10.
