pH/Cond 3400i Operation

4.3.2 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 or the temperature sensor of a conductivity measuring cell.

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:
