Probe evaluation
After the calibration, the measuring instrument evaluates the current
status of the probe 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.
Starting the calibration
Proceed as follows to calibrate the instrument:
Note
The sponge in the air calibration vessel must be moist (not wet). Follow
the instructions in the OxiCal
