This operation mode limits the input characteristic to the area between 20% and
100% of the analog signal. If the value for a characteristic point of the X axis is out-
side 0%, it is mapped to the characteristic point (2 V / 0 Hz).
The characteristic point on the X axis is calculated according to the following formula:
-7.60V
(X1=-70% / Y1=-50%)
