Calibration record
When finishing a calibration, the new calibration values are first
displayed as an informative message and stored.
Displaying the
calibration data
You can display the data of the last calibration (see section 4.4).
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 as
the sensor symbol and in the calibration record.
