AutoCal DIN
For this procedure, use two different standard buffer solutions accord-
ing to DIN 19266 (type A, C, D or F with pH values at 25 °C of: 1.679 /
4.006 / 6.865 / 9.180).
Note
Skip the steps 2 and 7 if you use a pH electrode with a temperature
sensor.
1
Press the <CAL> key repeatedly until the display Cd1 and the
function display AutoCal DIN appear. The sensor symbol dis-
plays the evaluation of the last calibration (or no sensor symbol
in the delivery state or after the measurement parameter has
been reset).
2
If required, enter the temperature of the first buffer solution with
<
▲> <▼> while keeping the <RUN/ENTER> key depressed.
3
Immerse the pH electrode in the first buffer solution.
4
Press the <RUN/ENTER> key.
The AR display indicator flashes.
The electrode voltage (mV) or the buffer nominal value ap-
pears on the display. Example:
