The calibration protocol contains the calibration data of the current cal-
ibration. You can transmit the calibration protocol to a printer via the se-
rial interface (see page 33).
Note
You can automatically print a calibration protocol after the calibration.
To do so, connect a printer to the interface according to section 4.5.3
before calibrating. After a valid calibration, the record is printed.

Relative Slope: 0,88
Probe: +++
After the calibration, the measuring instrument evaluates the current
status of the sensor against the relative slope. The evaluation appears
on the display. The relative slope has no effect on the measuring accu-
racy. Low values indicate that the electrolytic filling will soon be deplet-
ed and the probe has to be regenerated.
