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.
