4.2.5 Calibration result
Calibration evaluation After calibrating, the calibration data and current state of the sensor are
evaluated automatically. The asymmetry and slope are evaluated sep-
arately. The values must be within the following ranges:
Slope:
-50 ... -62 mV/pH
Asymmetry: -45 ... +45 mV
If one of the two values is outside the specified range the calibration is
evaluated as not successful, i.e. the sensor could not be calibrated.
A calibration procedure can have the following results:
