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).

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.
