Continuing with
three- to five-point
calibration
11. Immerse the pH sensor in buffer solution 2.
12. When measuring without temperature sensor:
Enter the temperature of the buffer with <><>.
13. Start the measurement with <ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
14. 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 next buffer appears (voltage display).
15. If necessary, finish the calibration procedure as a two-point calibration
with <M>.
The calibration record is displayed.
16. Thoroughly rinse the sensor with deionized water.
17. Immerse the sensor in the next buffer solution.
18. When measuring without temperature sensor:
Enter the temperature of the buffer with <><>.
19. Start the measurement with <ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
