Finalize a Calibration in Advance
If Home screen > Menu > Settings > Analysis settings > Finalize pH calibration at any point is active, a
button Calculate will display for the multi-point pH calibration. You can tap it to finalize the calibration in

To finalize the calibration in advance, proceed as follows:
Analysis settings is active.
The calibration is a multi-point pH calibration.
At least one calibration point of a multi-point calibration is passed.
1 Tap Calculate.
2 Tap OK (Adjust) to save the result.
- or -
Tap Reject to reject the calibration and return to Home screen.
The meter will do calibrations in the user-defined order in the active method. If one calibration point fails, you
should redo this calibration point and cannot skip it.
However, if Auto buffer recognition of a pH method is active, the meter will automatically recognize the closest
calibration point.

5.4 Starting a verification

The latest verification data will be stored into the data of the active sensor.
Ensure that the appropriate buffers/standards have been selected.

6 Tap Read.
7 The measurement stops when the endpoint criterion is fulfilled. See [Endpoint criterion Page 17].
A window pops up with verification data.
8 Tap OK.

5.5 Starting a measurement
