Result of the matrix adjustment
Evaluation
After the matrix adjustment, the system automatically evaluates the
current condition of the electrode(s) based on the drift voltage. For a
successful matrix adjustment, the drift voltage must be within the range
-45 mV to +45 mV. The drift voltage is set to 0 mV if you have selected
to zero the electrode.
At the end of the matrix adjustment procedure the drift voltage of all
selected electrodes is shown on the display. The evaluation is
displayed with "+" (successful) or "-" (unsuccessful). Additionally, the
slopes are displayed that are used for the current measured value
calculation. The slopes are marked by a star (*) as they were not
changed by the matrix adjustment.
Taking over the
determined values
For each successfully adjusted electrode you can individually decide
whether the values should be stored for measurement.
Note
If the matrix adjustment was erroneous due to an incorrect
determination or entry of the reference concentration, you can correct
the entry (if necessary several times). If, by doing so, it is not possible
to eliminate the error, the complete matrix adjustment has to be
repeated or discarded for this electrode. If it is discarded, measurement
is continued with the values of the last valid matrix adjustment (or
calibration). Values of successfully adjusted electrodes that were
already stored are retained.

The history of matrix adjustments can be viewed in the so-called
calibration history.
