2 If necessary, set the temperature of the first buffer solution with
<▲><▼>.
3 Immerse the pH combination electrode in the first buffer
solution (pH 7.0 ± 0.5 for two-point calibration).
4 Press the <ENTER> key.
The measured pH value appears on the display.
5 When the measured value is stable,
using <▲><▼>, set the measured value to the nominal pH
value of the buffer solution (at the current temperature).
6 Press the <ENTER> key. SLO appears on the display.
Note
Here you can cancel the calibration procedure with <M>. This
corresponds to a single-point calibration. The value of the zero point
(ASY) is displayed. The sensor symbol shows the evaluation of the
single-point calibration. Pressing <ENTER> displays the value of the
slope (SLO).
