The calibration is now finished with 2-point calibration; the electrode status is signalled with
the left bar display.
4. Rinse the electrode in distilled or deionised water and dry
5. Calibration point 3: "Pt. 3" (only with 3-point calibration)
Please observe that both an acidic and an alkaline calibration point are required for
a 3-point calibration.
Place the electrode and the
temperature sensor (if pre-
sent) in the third buffer
solution. (e.g. with standard
series: pH 10.01) and care-
fully stir.
As soon as a stable measure-
ment has been determined,
the instrument continues to
the next point.
Without temperature
sensor: Manual entry of
Buffer 3 temperature
Enter with the buffer temperature with but-

next calibration step is displayed.
The calibration is finished; the electrode status is signalled with the left bar display.
*1) For manual buffer setting (CAL Edit), the pH value of the solution must be entered with
the
or
buttons. With solutions of the Standard and DIN series, the pH value
of the respective solution is automatically recognised.
The value is adopted with
