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.
6 Wait for the end of the AutoRead measurement or accept the
calibration value with <MENU/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 <MENU/ENTER> .
The calibration is completed as a single-point calibration.
The new calibration values are displayed as a message (
i ).
You have the following options:
z Accept the new calibration values with <MENU/ENTER>.
Subsequently, the calibration record is displayed and output
to the interface at the same time.
z To switch to the measured value display without accepting
the new calibration values, press <M> or <ESC>.
