7.10.7 Performing a multi-point calibration (user level 3 only)
The multi-point calibration is performed with any number of calibration standards per sample stream that
you need to provide (Chapter 6.2 on page 82). The concentration of one of the standards should be at
least 50% and max. 100% of the work area end value. All other concentrations can be chosen freely.
Proceed as follows to perform a multi-point calibration:
1. Provide the appropriate calibration standards with different concentrations (see Chapter 6.2 on
page 82).
2. Fill the first calibration standard into a calibration vessel.
3. Position the calibration vessel in the analyser.
4. Open the start screen.
5. Switch to the "Calibration" display.
6. Select the sample current to calibrate.
7. Change to the "Calibration Settings" and adjust the values if necessary (Chapter 7.10.1 on
page 135).
8. Determine in which "Calibration Settings" the appropriate calibration vessel is located.
9. Switch back to the "Calibration" screen.
10. Switch to the "Calibration parameter setting" (actuation of the corresponding parameter).
11. Add any number of calibration points (depending on the number of calibration standards).
12. Adjust the "Concentration" setting to the appropriate calibration standard.
13. Perform the concentration adjustment for all calibration points and calibration parameters.
14. Switch back to the "Calibration" display and start the calibration.
15. Wait until calibration of the first calibration standard is completed.
16. Position the next calibration standard in the same place.
17. Perform the calibration of all provided calibration standards.
18. Activate the calibration after successful completion.
Notice
In user level 2, no multi-point calibration can be performed. If a multi-point ca-
libration is set, no default two-point calibration with user level 2 can be perfor-
med.
Notice
If the calibration does not complete successfully, contact LAR Technical Sup-
port (Chapter 15.1 on page 283).
