Note
For
single-point calibration
, the instrument uses the Nernst slope
(-59.16 mV/pH at 25 °C) and determines the zero point of the
electrode.
Continuing with two-

Wait for the end of the measurement with stability control or
accept the calibration value with
<ENTER>
.
The calibration display for the next buffer appears.
7
If necessary, terminate the calibration as a single-point
calibration with
<M>
.
The calibration record is displayed.
