4-3-1 Color Coordinates (Temperature)
Color temperature is a measurement of the
radiant energy transmitted by a color. For
computer monitors, the color temperature refers
to the radiant energy transmitted by white. Color
coordinates are the X and Y coordinates on the
chromaticity diagram of wavelengths for the
visible spectrum.

PROCEDURE
Use the directions in sections 4-3-2 through 4-3-4
to adjust the color coordinates for:
9300K to x = 0.283 ± 0.02, y = 0.298 ± 0.02
6500K to x = 0.313 ± 0.02, y = 0.329 ± 0.02
5000K to x = 0.346 ± 0.02, y = 0.359 ± 0.02

Select
COLOR CHANNEL 1
to control the
color for 9300K.
Adjust the luminance of the back raster to
between 0.3 to 1ft-L using the
G_CUT
controls.
Click on the << or >> box next to
B_CUT
to
set the “y” coordinate to 0.298 ± 0.02.
Click on the << or >> box next to
R_CUT
to
set the “x” coordinate to 0.283 ± 0.02.

Note:
If the above adjustments cannot be
done to each coordinate, click on the
<< or >> box next to
G_CUT
to decrease
or increase the green cutoff (bias) and
repeat procedures 2 and 3.

to make the video white.
(For 9300K color adjustment:
x = 0.283 ± 0.02, y = 0.298 ± 0.02.)
Note:
Do not touch the
G_GAIN
controls.
Check the ABL. If it is not within the
specifications (29 ± 1 ft-L), use the ABL
controls to adjust it.
