Adjustment procedure 1
(When a color differential meter is used)
1. First adjust the [MID-1] tone [G:].
2. Select adjustment point [No.2][G:].
When the background is not [G] monochrome,
press the [ENTER] key on the remote control to
switch to solid [G] monochrome.
3. Measure the illumination at adjustment points
No. 2, No.3, No.10 and No.11.
The values should be:
No.2 = Y2 [lx] No.10 = Y10 [lx]
No.3 = Y3 [lx] No.11 = Y11 [lx]
4. No.2 and No.3 adjustment points have the aver-
age of Y2 and Y3.
Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]
Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]
5. No.10 and No.11 adjustment points have the
average of Y10 and Y11.
Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]
Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]
6. Then adjust the [MID-1] tone [R] and [B].
When the background is [G] monochrome,
press the [ENTER] key on the remote control to
switch to solid white.
7. Measure the color coordinates of adjustment
point [No.1] and make a note of them.
Assume that they are x = x1, y = y1.
Note: When the CL-100 color and color differ-
ence meter is used, the [ ](delta) mode
is convenient. When adjustment point
[No.1] color coordinate has been select-
ed, set the slide switch on the side to
[ ](delta) while holding down the [F] but-
ton on the front panel. The measurement
shown after this displays the deviation
from measurement point 1.
8. Measure the color coordinates of measurement
point [No.2] and adjust [No.2][R:] and [B:] so
that the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010
9. Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates start-
ing in order from the small number points.
This completes adjustments required for
[MID-1].
Note: Since excessive correction may lead to a
correction data overview during internal
calculations, use the following values for
reference.
[No.2] to [No.5] ± 40 or less
[No.6] to [No.9] ± 50 or less
[No.10] to [No.13] ± 70 or less
[No.14] to [No.17] ± 120 or less
10. Then adjust the [MIN] tone [G] so that the ad-
justment values are two times as much as
MID-1] tone [G] values.
This completes [G] color adjustments.
11. Then adjust [MIN] tone [R] and [B].
Select [No.2] [B:] and press the [ENTER] key
on the Remote control transmitter to change to
solid white.
12. Measure the color coordinates of adjustment
point [No.1] and make a note of them.
Assume that they are x = x1, y = y1.
13. Now measure the color coordinates of mea-
surement point [No.2] and adjust [No.2][R:] and
[B:] so that the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010 (Target)
x = x1 ± 0.020 , y = y1 ± 0.040
14. Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates start-
ing in order from the small number points.
This completes [MIN] tone adjustments.
15. Now make similar adjustments for [MID-2] tone.
(Adjust [MID-2] tone [G] so that the adjustment
data set half as many as [MID-1] tone [G].)
16. Now make similar adjustments for [MID-3],
[MID-5], [MAX] tones. (It is not necessary to ad-
just the [G] data in these tones.)
17. After completing the step 16, set the value of
the [MID-4] tone [R]: [No.2] to the mean of the
values of the [R]: [No.2] in the [MID-3] and
[MID-4] tones.
18. Set all the values for the [No.2] to [No.17] of
the [MID-4] tone [R] and [B] in the same way as
the step 17.
19. Finally, set the data of the [MID-6] tone [R] and
[B] using the values of the [MID-5] and [MAX]
tones in the same way as the [MID-4] tone [R]
and [B] adjustments in the step 17 and 18.
