Zero point (1-point) calibration
With one-point offset calibration, the zero point of the pH combination
electrode is calculated, see chapter 8.3 "Zero point (1-point) calibration", page
53.
Recommended only for special applications, such as ultra-pure water.
2-point calibration
With two-point calibration, the zero point and slope of the combination
electrode are calibrated, see chapter 8.4 "2-point calibration", page 54.
This is the recommended calibration for most sensors.
