The first function, "Input scaling, pressure", defines the pressure range which is used by the
customized characteristic curve. Ideally, this range corresponds to the sensor limits.
In the calculation example, 0 and 2 bar are assumed. This means that with process pressure
of 0.5 bar, there is a value of 25% on the characteristic curve.
