pH/ 3400i
Operation
25
strument uses the Nernst slope (-59,2 mV/pH at 25 °C) and determines
the asymmetry of the electrode.
6
Thoroughly rinse the electrode with deionized water.
7
If required, enter the temperature of the second buffer solution
with <
▲> <▼> while keeping the <RUN/ENTER> key de-
pressed.
8
Immerse the pH electrode in the second buffer solution.
9
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:
10
When the measured value is stable, AR disappears. The value
of the slope (mV/pH) appears on the display. The probe symbol
shows the evaluation of the current calibration.
11
Press the <RUN/ENTER> key. The value of the asymmetry
(mV) appears on the display.
