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-
point calibration
( Buffer : TEC)
6 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.

8 Thoroughly rinse the combination electrode with distilled water.
9 Immerse the electrode in buffer solution 2.
