The non-linear range is between 0...75 mbar. For calibration
point 101, this means:
A pressure of 15 mbar, the transducer delivers 3.3 mbar instead
of the optimum value of 3.0 mbar. As 20 mA in the display
corresponds to 100.0 mbar, 3.3 mA in the display corresponds
to 16.5 mA before the correction. To correct this error, enter
“15.0“ at PN101.
