4.4.2 Automatic calibration (AutoCal)

For this procedure, use two or three buffer solutions of the selected

buffer set in any order.

Note

The steps 2, 6 and 10 are not necessary if you use a temperature

sensor.

1 Start the calibration with <CAL>.

The number of the specified buffer set is displayed (SET 1 ...

16).

The first buffer (BUFFER 1) of the buffer set (SET_x) is

requested.

2 If necessary, set the temperature of the buffer solution with

<▲><▼>.

3 Immerse the pH electrode in the first buffer solution.

4 Start the measurement with <OK>.

The SC display indicator flashes.

Depending on the setting, the display shows the nominal pH

value for the recognized buffer or the electrode voltage (mV).

As soon as a stable value is recognized, the next buffer

(BUFFER 2) is requested.
