Conversion from value on scale (phys) into measure value (raw value in mV)
Information
From PUMA Open version 1.5 onward, it is checked, whether the input values
are within the specified range. You find the valid ranges in the F-FEM Parameter-
ization manual.
Make sure that the adjustment- and calibration points are within the valid range!
