Operation pH/ 3400i 4.3 Why calibrate? When to calibrate? pH calibration pH electrodes age. This changes the asymmetry (zero point) and slope of the pH electrode. As a result, an inexact measured value is displayed. Calibration determines the current values of the asymmetry and slope of the electrode and stores them in the measuring instrument. Thus, you should calibrate at regular intervals.
pH/ 3400i Operation Note You can automatically print a calibration protocol after the calibration. To do so, connect a printer to the interface according to section 4.7.2 before calibrating. After a valid calibration, the record is printed.

Lists pH/ 3400i Glossary Adjusting To manipulate a measuring system so that the relevant value (e. g. the displayed value) differs as little as possible from the correct value or a value that is regarded as correct, or that the difference remains within the tolerance. Asymmetry Designation for the offset potential of a pH electrode.
pH/ 3400i Lists Offset potential The measurable potential of a symmetrical electrode, the membrane of which is immersed in a solution with the pH of the nominal electrode zero point. The asymmetry is part of the offset potential. ORP voltage The ORP is caused by oxidizing or reducing substances dissolved in water if these substances become effective on an electrode surface (e. g. a gold or platinum surface). pH value The pH is a measure of the acidic or basic effect of an aqueous solution.
