8 To continue the two-point calibration, thoroughly rinse the elec-
trode with deionized water.
9 If necessary, enter the temperature of the second buffer solution with
<▲> <▼>.
10 Immerse the pH electrode in the second buffer solution.
11 Press the <RUN/ENTER> key. The second pH value appears on the
display.
12 Set the measured value to the nominal pH value of the buffer solution
(at the current temperature) with <▲> <▼>.
13 When the measured value is stable, press the <RUN/ENTER> key.
The value of the slope (mV/pH) appears on the display. The probe
symbol shows the evaluation of the current calibration.
14 Press the <RUN/ENTER> key. The value of the asymmetry (mV) ap-
pears on the display.
