7.10.5 Performing a pre-set two-point calibration (user level 2)
The pre-set two-point calibration is performed with one calibration standard per sample stream, which
must be provided by you (see Chapter 6.2 on page 82). The concentration of the standard is preset.
1. Provide the appropriate calibration standard (Chapter 6.2 on page 82).
2. Fill the calibration standard in a calibration vessel.
3. Open the start screen.
4. Switch to the "Calibration" display.
5. Select the sample current to calibrate.
6. Make sure at which position the calibration vessel has to be positioned (see Settings - vessel).
7. Position the calibration vessel in the analyser.
8. Start the calibration.
9. Wait for the calibration to finish.
10. Activate the calibration after successful completion (see chapter 7.10.2 on page 152).
7.10.6 Carrying out a two-point calibration (user level 3 only)
The two-point calibration is performed with one calibration standard per sample flow, which must be pro-
vided by you (see Chapter 6.2 on page 82). The concentration of the standard depends on the set work
area. It should be at least 50% and max. 100% of the work area end value.
1. Provide the appropriate calibration standard (Chapter 6.2 on page 82).
2. Fill the calibration standard in 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
146).
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. Adjust the "Concentration" setting to the appropriate calibration standard.
12. Perform the concentration adjustment for all displayed parameters.
13. Switch back to the "Calibration" display.
14. Start the calibration.
15. Wait for the calibration to finish.
16. Activate the calibration after successful completion.
Notice
If the calibration does not complete successfully, contact LAR Technical Sup-
port (Chapter 15.1 on page 283).
