Printing the
calibration record
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 35).
Note
You can automatically print a calibration record after the calibration. To
do so, connect a printer to the interface according to section 4.5.3 be-
fore calibrating. After a valid calibration, the record is printed.

Sensor evaluation
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 electrolyte will soon be depleted and
the sensor will have to be regenerated.
