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