Note
At this point, the AutoCal TEC calibration can be terminated with <M>.
This corresponds to a single-point calibration. To do this, the instru-
ment 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 Thoroughly rinse the electrode with distilled water.
7 If required, enter the temperature of the second buffer solution
with <
▲> <▼> while keeping the <RUN/ENTER> key de-
pressed.
8 Immerse the pH electrode into 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:
