pH calibration
"Manual data entry"
The numeric values for electrode zero point and slope are entered numerically and by
hand.
Calibration pH
"Calibration with manual buffer" / "Calibration with fixed buffer" /
"Calibration with automatic buffer recognition"
Manual buffer
: The buffer pH value is entered manually. The display then shows the
current measured value.
Fixed buffer
: In the Calibration menu from s. page 84 onwards, you can set two buffer
solutions or define them yourself. The selected pH value and buffer type are displayed.
Automatic buffer recognition
: The device automatically recognises the used buffer.
Preselect the buffer types (e.g. E+H) in the Calibration menu.

Recalibrate
End of calibration
Accept
: Pressing "E" accepts the new calibration data.
Reject
: The data is not accepted, a recalibration won’t
be started.
Recalibrate
: The data is rejected and a new calibration
will be started.
