7.10.8 Auto-Calibration (only User Level 3)
There is the possibility of automatic calibration at certain intervals. For this, a calibration vessel with a
calibration standard must be permanently present in the analyser. For auto calibration, the settings must
be made on the Calibration Settings screen and Auto Calibration must be enabled.
To enable auto-calibration, follow the instructions below:
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 in position "V1" (Fig. 11, page 25).
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. In the "Calibration Settings", determine that the calibration vessel is in position "V1".
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 to the "Calibration" display.
14. Switch to the "Calibration Settings".
15. Set the interval at which the analyser should be calibrated.
16. Enable auto-calibration.
17. Change the calibration standard if necessary, paying attention to the concentrations.
Notice
If the calibration does not complete successfully, contact LAR Technical Sup-
port (Chapter 15.1 on page 283).
