4.4 Customer-specific calibration
The customer-specific calibration changes the curve of measured values
comparedtotherealmeasuredvalues(shifting/changeofthegradient;→9.4.6
[CAL])�
• Two calibration points can be defined (CP1, CP2)� The two points are
independent of each other�
• Thetwocalibrationpointsmustbewithinthescaledmeasuringrange(→4.3
Pressure monitoring / analogue function)�
• The zero point calibration [COF] influences the calibration of the curve of
measuredvalues.Recommendation:set[COF]to0(→9.4.1[COF]),then
calibrate the curve of measured values�
Afterachangethecalibrationcanberesettofactorysetting(→9.5.2[rES]).
