8.7. Calibration Offset
Professional function to calibrate the temperature sensors. Standard
value is zero and should not be altered in the normal case. An adjustment
may become necessary if sensors of other manufacturers are used.
Internal formula for the temperature calculation, see Fehler! Verweisquelle

8.8. Calibration Factor
Professional function to calibrate the temperature sensors. Standard
value is zero and should not be altered in the normal case. An adjustment
may become necessary if sensors of other manufacturers are used.
The internally used formula to calculate the temperature is:
237+Offset-(44,15-Factor)*ln(measured value) (Output is value in °C)
I thank you for your answer. Indeed, if you used a ln function for your program, it is the reason why the factor seemed not having a different influence than the offset. Initially, I supposed it was a linear function !
