close to neutrality, the procedure will fail.
•
During normal operation, it is possible to view the offset (pressing
) and gain (pressing
)
values, to check the electrode status. The ideal values are an offset close to zero and a gain close
to 1.000. When these values are close to the max / min limits (offset: -1.00pH ... +1.00pH; gain:
0.750 ... 1.500), the electrode is contaminated or dead.
Redox Calibration
1. Rinse the electrode with distilled water, then immerse it in the calibration solution (e.g. 220 mV).
2. Press the CAL key to enter the menu mode and use the
/
keys
to select the option “IN2 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 solution value (220 mV).
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.
Notes
•
If the system does not automatically recognize the buffers or
the “Calibration Impossible” error occurs, it can be due to:
a) Calibration solution contaminated or expired.
b) A faulty or defective electrode.
c) Connection cable or connector damaged.
•
During normal operation, it is possible to view the offset value by pressing
, to check
the electrode status. The ideal offset value is close to zero. When this value is close to
the max / min limits (-100mV ... +100mV), the electrode is contaminated or dead.
Manual Mode
At any time you can force a manual working mode, useful for a temporary
use of the system. If a password has been set (see parameter P16), the
system will require it to enable the access to this feature.
1. Press the CAL key to enter the menu mode and use the
/
keys to select the option
1. “MANUAL FUNC.1” (or “MANUAL FUNC.2”).
2. Press CAL again to confirm.
3. Similarly proceed for pump 2.
4. Press ESC at any time to exit the manual mode.
