17. Wait for the measurement with stability control to be completed or termi-
nate the stability control and take over the calibration value with
<ENTER>.
The calibration display for the setting of the nominal buffer value appears.

18. Set the nominal buffer value for the measured temperature with
<><>.
19. Accept the set calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
20. Finish the calibration procedure as a two-point calibration with <M>.
The calibration record is displayed.
21. Thoroughly rinse the electrode with deionized water.
22. Immerse the electrode in the next buffer solution.
23. When measuring without temperature sensor:
Measure the temperature of the buffer and enter it with <><>.
24. Start the measurement with <ENTER>.
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.
25. Wait for the measurement with stability control to be completed or termi-
nate the stability control and take over the calibration value with
<ENTER>.
The calibration display for the setting of the nominal buffer value appears.
