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.

Wait for the end of the AutoRead measurement or
Terminate
AutoRead
and accept the calibration value with
g
.
The calibration display for the next buffer appears.
9
For single-point calibration, select
Exit with one point calibra-
tion
with
82
and confirm with
g
.
The calibration is completed as a single-point calibration.
The new calibration values are displayed as a message (
i
).
You have the following options:
!
Accept the new calibration values with
g
. 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
