Using <> <>, select Continue and press <START/EN-
TER>. The buffer is measured.
The measured value is checked for stability (AutoRead).

Wait for the end of the AutoRead measurement or accept the
calibration value with <START/ENTER>.
The calibration display for the next buffer appears.

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 (

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>.
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.
