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 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 key.
The value of the zero point (ASY) is displayed.

13

Press the key.
The value of the slope (SLO) is displayed.

14
