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