14. Immerse the electrode in the second buffer solution.
15. When measuring without temperature sensor:
– Temper the buffer solution, or measure the current temperature.
– Enter the temperature value in the menu.
16. 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.
17. Wait for the measurement with stability control to be completed or termi-
nate the stability control and take over the calibration value with
The calibration display for the setting of the nominal buffer value appears.
