4.3.3 Result of the calibration
Evaluation With calibration, the system automatically evaluates the condition of a
combination electrode based on the data of its characteristic curve. The
drift potential and slope are evaluated separately. For a calibration
procedure to 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.
Note
Actions for error elimination are given in chapter 8 W
HAT TO DO IF ....
Value of the slope: 50 ... 70 mV
Drift voltage: -45 ... +45 mV
