12.3 Zero point calibration
1. Press the "MODE" soft key. Switch to the manual mode if you are not already in this mode.
2. Remove the standard solution that is present, together with the hose. Alternatively, remove
the hose from the liquid manager, allow the hose to drain and dry the hose well. This
prevents any contamination of the zero standard.
We recommend the use of a separate hose.
3. Connect the zero standard to the liquid manager, connection S1.
4. Select "Menu/Operation/Maintenance/Bottle change mode/Bottle insertion/Bottle
selection".
5. Select "Standard 1" and confirm with "OK".
6. Select "Confirm bottles inserted".
7. Go to "Menu/Operation/Manual operation" and select " Determine zero point".
8. Perform zero point calibration twice, one directly after the other.
The values should differ only marginally (0.1 mg/l NH

-N).
9. Following successful calibration, you will be asked: "Do you want to accept the calibration
data for adjustment?"
10. Remove the zero standard. Either use the additional hose in order to reconnect the standard
calibration solution or allow the hose to drain and dry the hose well.
11. Connect the standard calibration solution to the liquid manager.
12. Select "Menu/Operation/Maintenance/Bottle change mode/Bottle insertion/Bottle
selection".
13. Select "Standard 1" and confirm with "OK".
14. Select "Confirm bottles inserted".
It is advisable to then perform a manual calibration with the standard solution.
