INFO
Selection for calibration
(only two-circuit)
Select electrode 1 or 2, and then run through calibra-
tion for each individual electrode.
Note in display
Display of the type of on-site calibration selected in the
calibration settings.
Enter temperature,
(only if "Calibrate with MTC" is selected)
Confirm by pressing
Enter buffer temperature
(only if "Calibrate with MTC" is selected)
Confirm by pressing
Handling instructions
Immerse the electrode in buffer 1 / 2.
Confirm by pressing
Enter pH value of buffer 1 / 2
(only with manual buffer)
Confirm by pressing
MTC Checks the stability of the calibration
7.00 Wait until the pH measurement is stable:
0 Time does not count down,
25.0 pH value no longer flashes,
Display "Measured value stable"
Confirm by pressing
Note in display:
If an error is present (e.g. incorrect buffer used), this
message is displayed.
07.00 Note in display:
Info on electrode 1 / 2.
59.00 Data on the zero point, slope and calibration quality.
Note in display:
Electrode status circuit 1 / 2:
There are three status messages for the electrode sta-
tus: "good", "OK.", "bad". If the status is displayed "bad",
electrode replacement is recommended to ensure the
quality of the pH measurement.

End of calibration
Accept: Pressing
Reject: The data is not accepted and the device has
not been recalibrated.
Recalibrate: The data is rejected and the device is
recalibrated.
Note in display:
If the electrode is back in the medium, so that
measurement can take place?
