Note
At this point, the AutoCal TEC calibration can be terminated with <M> . This
corresponds to a single-point calibration . For this, the instrument uses the
Nernst slope (-59.2 mV/pH at 25 °C) and determines the asymmetry of the
electrode.
5 When the measured value is stable, Ct2 appears.
6 To continue the two-point calibration , thoroughly rinse the
electrode with deionized water.
7 If necessary, enter the temperature of the second buffer solu-
tion with

8 Immerse the pH electrode in the second buffer solution.
9 Press the <RUN/ENTER> key.
The AR display indicator flashes.
The electrode voltage (mV) or the buffer nominal value ap-
pears on the display. Example:
