5 Wait for the end of the measurement with stability control or
accept the calibration value with <MENU/ENTER>.
The calibration display for the next buffer appears.

6 If necessary, finish the calibration procedure as a single-point
calibration with <M>.
The calibration record is displayed.
Note
For single-point calibration, the instrument uses the Nernst slope
(-59.2 mV/pH at 25 °C) and determines the zero point of the IDS pH
sensor.
7 Thoroughly rinse the IDS sensor with distilled water.
8 Immerse the IDS pH sensor in buffer solution 2.
9 Start the measurement with <MENU/ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parame-
ter flashes.
