Electrochemical Calibration pH Calibration
1. Rinse the pH electrode with distilled water, then immerse it in the pH 7.01 pH buffer solution.
2. Press the CAL key to enter the menu mode and use the
/
keys
to select the option “IN1 CALIBRATION”.
3. Press CAL again to confirm.
4. Press
to select the OFFSET calibration and confirm by pressing CAL.
5. The system automatically recognizes and displays the buffer value (7.01 pH).
6. If necessary, use the
/
keys to adjust the calibration value.
7. Press CAL to confirm the calibration, or ESC to quit the
procedure and keep the previous calibration.
8. Rinse the pH electrode with distilled water, then immerse
it in the pH 4.01 (or 9.01) buffer solution.
9. Press the CAL key to enter the menu mode and use the
/
keys
to select the option “IN1 CALIBRATION”.
10. Press CAL again to confirm.
11. Press
to select the GAIN calibration and confirm by pressing CAL.
12. The system automatically recognizes and displays the buffer value (4.01 or 9.01 pH).
13. If necessary, use the
/
keys to adjust the calibration value.
14. Press CAL to confirm the calibration, or ESC to quit the
procedure and keep the previous calibration.
Notes
•
If the system does not automatically recognize the buffers or the
“Calibration Impossible” error occurs, it can be due to:
a) Buffer solution contaminated or expired.
b) A faulty or defective electrode.
c) Connection cable or connector damaged.
•
If you try to calibrate the offset at a pH value too different from 7.00, the calibration is
automatically ignored. Similarly if you try to calibrate the gain with a buffer solution at a pH too
