CIE
These measured value windows display the color coordinates in the respective CIE standard color system and depict
chromaticity graphically in the associated standard color diagram. The window as well as all or one preferred
standard color system can be shown or hidden with the help of the corresponding function in the presentation menu
(see section 4).
CIE 1931
Standard color system, graphic
– chromaticity in the standard color diagram, color coordinates x, y
CIE 1960
Standard color system, graphic
– chromaticity in the standard color diagram, color coordinates u, v
CIE 1976
Standard color system, graphic
– chromaticity in the standard color diagram, color coordinates u', v'

Data
This measured value window displays irradiance either as original data from the sensor or as data interpolated to
even 5 nm steps. The window as well as the preferred display format can be shown or hidden with the help of the
corresponding function in the presentation menu (see section 4).
