be valid, the potential level, slope and drift voltage must be within
certain ranges.
Valid ranges for slope and drift potential:
The valid potential levels (MIN, MAX) can be taken from the online help.
Taking over the
determined values
For each successfully calibrated electrode you can individually decide
whether the values should be stored for measurement.
Sensor history The result of the calibration is available in the Sensor history (see
section 4.4 S
ENSOR HISTORY
).
4.4 Sensor history
The data of the calibration procedures and matrix adjustments are
available in the Sensor history and in the calibration history.
The sensor history supplements and expands the calibration history:
 The results of any checks are displayed.
 All data of all electrodes of the sensor can be displayed in one list.
 More datasets can be displayed for each electrode.
