4-3-2 (d) WHITE BALANCE ADJUSTMENT VERIFICATION
CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Back raster pattern
X-Y Coordinates: x = 0.283 ± 0.02,
y = 0.297 ±0.02
Raster Luminance 0.3 ~ 1ft-L
ABL Luminance 30 ± 1 ft-L
Brightness: Cut-off
Contrast: Maximum
1. Check whether the color coordinates of the
back raster satisfy the above spec.
If they do not, return to 4-3-2 (a) and readjust
all settings.
2. Display a full white pattern.
Note: Do not touch the G_GAIN controls.
3. Adjust the Contrast Control on the monitor so
that the luminance of the video is about 5 ft-L.
4. Check whether the white coordinates of the
video meet the above coordinates spec.
5. Adjust the Contrast Control again so that the
luminance of the video is about 20 ft-L.
6. Check whether the white coordinates of the
video satisfies the above spec.
If they do not, return to 4-3-2 (a) and readjust
all settings.
4-3-3 Color Adjustments for 6500K
4-3-3 (a) BACK RASTER COLOR ADJUSTMENT
CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Back raster pattern
Brightness: Cut-off
Contrast: Maximum
1. Select COLOR CHANNEL 2 to control the
color for 6500K.
2. Adjust the luminance of the back raster to
between 0.3 to 1.0 ft-L using the G_CUT
controls.
3. Click on the << or >> boxes next to R_CUT
and B_CUT to adjust the R-Bias to x = 0.313 ±
0.02 and the B-Bias to y = 0.329 ± 0.02.
4-3-3 (b) G-GAIN ADJUSTMENT
This procedure is the same as that for 9300K, refer
to the procedure on page 4-5.
4-3-3 (c) WHITE BALANCE ADJUSTMENT
CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Full white pattern
Brightness: Cut-off
Contrast: Maximum
1. Click on the << or >> boxes next to R_GAIN
and B_GAIN to make the video white.
(For 6500K color adjustment:
x = 0.313 ± 0.02, y = 0.329 ± 0.02.)
2. Refer to the procedure for 9300K, section
4-3-2 (c) steps 2 and 3.
4-3-3 (d) WHITE BALANCE ADJUSTMENT VERIFICATION
Refer to the procedure for 9300K, section 4-3-2 (d).

4-3-4 (a) BACK RASTER COLOR ADJUSTMENT
CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Back raster pattern
Brightness: Cut-off
Contrast: Maximum
1. Select COLOR CHANNEL 3 to control the
color for 5000K.
2. Adjust the luminance of the back raster to
between 0.3 to 1.0 ft-L using the G_CUT
controls.
3. Click on the << or >> boxes next to R_CUT
and B_CUT to adjust the R-Bias to x = 0.346 ±
0.02 and the B-Bias to y = 0.359 ± 0.02.
4-3-4 (b) G-GAIN ADJUSTMENT
This procedure is the same as that for 9300K, refer
to the procedure on page 4-5.
Adjust the brightness of the G_GAIN less 5 ft-L
than brightness of procedure for 9300K.
4-3-4 (c) WHITE BALANCE ADJUSTMENT
CONDITIONS
Scanning frequency: 68 kHz/85 Hz
Display image: Full white pattern
Brightness: Cut-off
Contrast: Maximum
1. Click on the << or >> boxes next to R_GAIN
and B_GAIN to make the video white.
(For 5000K color adjustment:
x = 0.346 ± 0.02, y = 0.359 ± 0.02.)
2. Refer to the procedure for 9300K, section
4-3-2 (c) steps 2 and 3.
