Do not withdraw the electrode from the solution until the measurement is over.
If you want to abort the calibration of the electrode, long-press the
END
, key before the end of the measurement.
Choose the calibration set by long presses on the ▲ and
▼ keys. The values of the buffer solutions supplied are
in set 1.

The pH values of the calibra-
tion set are scrolled.
Confirm the set by pressing the
CAL
key.
When the instrument detects the buffer solution value, it
displays it, corrected for temperature, in alternation with
the temperature.

Otherwise, when the measurement has stabilized
,
the first calibration point is applied. The instrument then informs
you that you can calibrate a second point.
The value of the buffer solution of the calibration set is always
displayed in alternation with the temperature.
The
CAL
and
END
symbols are also displayed in alternation,
indicating that you can continue or terminate the calibration.
If you need only one calibration point, long-press the
END
key. Only the offset of the electrode will be calculated; the slope will
be left unchanged.
The instrument exits from the calibration procedure and briefly displays the slope and the offset before switching back to
measurement mode.
