8. Wait for the end of the measurement with stability control (beep,
[HOLD][AR] status indicator) or take over the calibrated value with

The calibration display for the next buffer appears (voltage display).
9. If necessary, finish the calibration procedure as a single-point calibra-

tion with .
The calibration record is displayed.
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.
10. Thoroughly rinse the sensor with deionized water.
11. Immerse the pH sensor in buffer solution 2.
12. When measuring without temperature sensor:
Enter the temperature of the buffer with

The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
