7. When measuring without temperature sensor:
– Temper the buffer solution, or measure the current temperature.
– Enter the temperature value in the menu.
8. Start the measurement with
The measured value is checked for stability (stability control). The [AR]
status indicator is displayed. A progress bar is displayed and the display
of the measured parameter flashes.

11. Accept the set calibration value with
The calibration display for the next buffer appears (voltage display).
12. If necessary, finish the calibration procedure as a single-point calibration

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 elec-
trode.
13. Thoroughly rinse the electrode with deionized water.
