pH/ 3400i Operation

Note
At this point, the AutoCal DIN calibration can be terminated with <M>.
This corresponds to a single-point calibration. When doing so, the in-
strument uses the Nernst slope (-59,16 mV/pH at 25 °C) and deter-
mines the asymmetry of the electrode.
5 When the measured value is stable, Cd2 appears.
6 Thoroughly rinse the electrode with deionized 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 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:
