The buffers required for the calibration of a pH sensor can be defined
individually or a predefined buffer series can be used. Many buffer solution
manufacturers offer complete buffer series. Calibration with two buffer
solutions (two-point calibration) is normally adequate.
Softkeys
[Preset
series]
lists all the buffer solutions of the selected manufacturer
or type in the buffer table.
[Add
series]
adds the whole list of buffer solutions of the selected
manufacturer or type to the existing buffer table.
[Start
Stop]
starts or stops a measurement.
[Clear
calibr.]
deletes the existing calibration or the calibration data. The
buffer table used for this can remain if the query shown
on deletion is answered with 'n'.
[Cancel
calibr.]
breaks the started calibration off. The previous calibration
data are restored and the calibration window closed.
[Show
curve]
shows the currently valid calibration curve, see example
below.
As in titrations and measurements, the measuring parameters can be
individually selected for the sensor calibration.
