Note
While the zero point (ASY) is being displayed, you can change the unit
of the zero point with
<▲><▼>.
While the slope (SLO) is being displayed, you can change the unit of
the slope with
<▲><▼>.
The % display refers to the Nernst slope of 59.2 mV/pH at 25° C
(100 x determined slope/Nernst slope).
The units of the zero point and slope can also be changed permanently
in the measurement settings (see section 4.5.2).
7 To continue the two-point calibration, thoroughly rinse the
combination electrode with deionized water.
8 If necessary, set the temperature of the second buffer solution
with <▲><▼>.
9 Immerse the combination electrode in the second buffer
solution.
10 Press the <ENTER> key. The second pH value appears on the
display.
11 When the measured value is stable,
using <▲><▼>, set the measured value to the nominal pH
value of the buffer solution (at the current temperature).
12 Press the <ENTER> key.
The value of the zero point (ASY) is displayed.
13 Press the <ENTER> key.
The value of the slope (SLO) is displayed.
14 Press the <ENTER> key.
The measuring mode is active.
