7.2.6 Amplifier of the input characteristic (An.05...07, An.15...17, An.25...27)
With these parameters the input signals can be adapted in X and Y direction as well as in the rise to the
requirements. In the case of factory setting no zero point offset is adjusted, the rise (gain) is 1, i.e. the input
value corresponds to the output value of this step (see Fig. 7.2.6.a). The output value is calculated according
to following formula:
Out = Amplification • ( In - Offset X) + Offset Y
