Operation pH/ 3400i

Sample printout:

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
