To enter the menu, proceed as follows:
pH calibration
"Manual data entry" (
)
The numeric values for electrode zero point and slope are entered numerically and by
hand.
pH calibration
"Calibration with manual buffer" / "Calibration with fixed buffer" /
"Calibration with automatic buffer recognition"
Buffer manual
: The buffer pH value is entered manually. The display then shows the cur-
rent measured value.
Fixed buffer
: In the calibration menu from page 50 onwards, you can set two buffer solu-
tions or define them yourself. The selected pH value and buffer type are displayed.
Automatic buffer recognition
: The device automatically recognises the used buffer.
Select the buffer types (e.g. E+H) in the Calibration menu.
!
Note!
The automatic buffer recognition is only possible with glass electrodes.

End of calibration
Accept
: Pressing
F
accepts the new calibration data.
Reject
: The data is not accepted and the device has
not been recalibrated.
Recalibrate
: The data is rejected and the device is
recalibrated.

Electrode in medium?
Note in display:
If the electrode is back in the medium, so that measure-
ment can take place?
