Calibration evaluation After calibrating, the meter automatically evaluates the calibration. The
zero point and slope are evaluated separately. The worse evaluation of
both is taken into account. The evaluation appears on the display and
in the calibration record.
Note
For pH IDS sensors, you can optionally enable a more finely graded
calibration evaluation (QSC) (see section 4.6.10).
Preparatory activities Perform the following preparatory activities when you want to calibrate:
4.6.5 Calibration interval
The calibration evaluation is displayed as a sensor symbol.
After the QSC function has been enabled the sensor symbol is
replaced by the QSC color scale (see section 4.6.10).
After the specified calibration interval has expired, the sensor symbol
