4-1 Overview
The meter is supplied with calibration by mV signal that simulates an ideal pH
electrode mV output (0 mV at pH 7, based on 25°C working temperature). Ho-
wever, because most pH electrodes do not exactly replicate the ideal electrode and
because the working temperature may differ from 25°C, it is necessary to calibrate
the instrument to ensure measurement accuracy of the combined pH electrode.
