Editing calibration
You can edit a calibration by:
¡
Selecting a regression type
You can select either linear or quadratic regression. The software displays the calibration
coefficients and method characteristics for the selected regression type.
¡
Deactivating individual measuring points
All measuring points activated via check mark in the results table in the No. column are
included in the regression calculation. You can deactivate a measuring point by remov-
ing the check mark. To do this, click in the No. column.
If you deactivate all measuring points, the software removes the check mark for the en-
tire calibration channel.
¡
Deactivating individual measured values
You can view individual measured values by clicking on the button at the end of each
line of the table. You can then deactivate individual measured values by removing the
check mark in the use column.
¡
Enabling/disabling measured values for preparation water
You can view the individual measured value determined for the preparation water by
clicking on the [Edit] button. You can then activate or deactivate individual measured
values.
¡
Adding measuring points
You can add additional measuring points to an existing calibration. Perform a calibration
measurement with the same method. When the measurement is complete, select the
calibration report with the [Add measuring point]. Add the new measuring points indi-
vidually to the calibration.
The software recalculates the calibration coefficients, method characteristics and the re-
gression diagram after each change.
5.4.4
Linking a calibration to a method
Link the calibration parameters to a method as follows:
}
Select the calibration range for the respective parameters (e.g., NPOC).
Up to three
linear calibration ranges
per parameter can be linked to a method.
These ranges must overlap and be without gaps.
With
quadratic calibration functions
, only one calibration range can be linked to the
method.
}
Activate the Use calibration field with a check mark for each calibration range and
analysis parameter to link with a method.
Not all calibrated parameters need to be transferred to the method.
}
Click the [Link with method] button.
}
Answer the following query: Link with the calibration method?
– [Yes] (normal). The software links the calibration to the calibrated method.
– [No]. The software links the calibration to a method of your choice. The software
does not check whether the method parameters of the calibration match those of
the selected method here.
ü
The Link with method: (...) window opens.
The window displays the previous current calibration coefficient (right column) and the
newly determined calibration coefficient (left column). The parameter display (e.g., IC/
NPOC) can be changed.
