Note

For single-point calibration, the instrument uses the Nernst slope

(-59.16 mV/pH at 25 °C) and determines the asymmetry of the elec-

trode.

5 Using <▲><▼>, select Continue and press <START/EN-

TER>. The buffer is measured.

The measured value is checked for stability (AutoRead).

6 Wait for the end of the AutoRead measurement or accept the

calibration value with <START/ENTER>.

The calibration display for the next buffer appears.

7 For single-point calibration, select Exit with one point calibra-

tion with <▲><▼> and confirm with <START/ENTER>.

The calibration is completed as a single-point calibration.

The new calibration values are displayed as an informative

message (

i).

You have the following options:

! Accept the new calibration values with <START/ENTER>.

Subsequently, the calibration record is displayed and output

to the interface at the same time.

! To switch to the measured value display without

accepting

the new calibration values, press <M> (short pressure) or

<ESC>.
