a question - where exactly in SpectraView II (not that EU version of BasicColor Display) you have this option to generate correction matrices (that requires you to hook up both spectrophotometer and colorimeter, in sequence, to the same panel) for colorimeters ?
Old text, copy and paste so forgive the names of older devices:
How to use an iOne Pro/Monitor to create an offset for an iOne Display / DTP94 when calibrating the LCD2690WUXiBackground:
The iOne Pro is much better at measuring color on wide gamut displays than the iOne Display or DTP94. However it suffers from noise and drift at low luminance which makes it somewhat unsuitable for creating a perfect greyscale. The iOne Display and DTP94 may give white point errors due to the nature of the wide color gamut display, but are much better at measuring low luminance.
The two devices can be used in combination to create a correction offset which will lead to much better results. This involves first calibrating the display with the iOne Pro/Monitor, measuring the resulting white point with the iOne Display / DTP94 and creating a new target based on that measured white point.
Steps:
1. Connect the iOne Pro/Monitor
2. Select the desired Target in SpectraView and calibrate the display.
3. Confirm that the calibrated white point is acceptable (judge 100% white only).
4. Disconnect the iOne Pro/Monitor and connect the iOne Display / DTP94.
5. Open the SpectraView Preferences dialog.
6. Re-detect the color sensor.
7. Change the "Primary Colors Chromaticity Source" to "Factory Measurement"
8. Click OK.
Next you will create a new Target with a custom white point that has been adjusted with the offset between the two devices:
1. In SpectraView, click the "Edit Target settings" icon.
2. Click the "Edit..." button in the "White Point" group.
3. Click the "Measure" button and measure the white patch on the screen using the iOne Display / DTP94.
4. The CIE xy values should be filled in automatically.
5. Click OK.
6. Click OK.
7. Enter a new name for the Target file.
8. Make sure the new Target is selected, and calibrate using the iOne Display / DTP94.
The white point should match what you got with the iOne Pro/Monitor, and the greyscale should be much better.
