calibration solution.
3. Enter the maximum CV in% for calibration in the Perform Calibration screen.
4. After selecting the solution number, it will be displayed in user level 3 in the "Service Calibration"
screen.
5. Click on the solution to display the streams.
6. When you click on the measured current, the five repetitions (signals) are displayed.
7. Click in the input field to enter the ingredients of the solution.
8. Double-click in the input field. The number pad and keyboard are displayed. Please enter the
appropriate concentration (3).
9. To accept the calibration concentration, save it with the "floppy disk" symbol.
10. Activate all check boxes for the current and the solution to be measured.
11. Start the calibration via the "Start calibration" button
12. Raw values of the calibration can be viewed immediately in the table. When all calibration passes
have been completed, raw values are available for each signal (repetitions). To the right of the
stream is the mean value of the raw values (5). All check boxes are enabled for the measured
solution and current. Outliers are detected by the software and highlighted in yellow. These outliers
are not included in the calculation.
13. If you are sure that the 5 measurements (signals) have an outlier that was not detected by the
software, this can be removed from the calculation by deactivating the corresponding check box.
14. In the screen "Calibration results" (user level 2), the results of the calibration (slope and intercept)
can be viewed and activated.
Perform a multi-point calibration (three solutions) for a sample stream:
1. Make a calibration solution and position the calibration vessel in the analyser.
2. In the "Calibration solutions" selection box at user level 2, "Perform calibration" screen, select the
calibration solution.
3. Enter the maximum CV in% for calibration in the Perform Calibration screen.
4. After selecting the solution number, it will be displayed in user level 3 in the "Service Calibration"
screen.
5. Click on the first solution to display the streams.
6. When you click on the measured current, the five repetitions (signals) are displayed.
7. Click in the input field to enter the ingredients of the solution.
8. Double-click in the input field. The number pad and keyboard are displayed. Please enter the three
concentrations (3).
9. To accept the calibration concentrations, save them with the "floppy disk" symbol.
10. Activate all check boxes for the current to be measured and the three solutions.
11. Start the calibration via the "Start calibration" button
12. Raw values of the calibration can be viewed immediately in the table. When all calibration passes
have been completed, raw values are available for each signal (repetitions). To the right of the
stream is the mean value of the raw values (5). All check boxes are enabled for the measured
solution and current. Outliers are detected by the software and highlighted in yellow. These outliers
are not included in the calculation.
13. If you are sure that the 5 measurements (signals) have an outlier that was not detected by the
software, this can be removed from the calculation by deactivating the corresponding check box.
Notice
In a multi-point calibration, it must be noted that the calibration solutions can only be
measured one after the other.
In the Service Calibration screen, the first left check box is responsible for the entire
row. If this checkmark is removed (disabled), all others in the series will be disabled.
