Adjustment procedure 1
(when a color differential meter is used)
1. First adjust [MIN] tone [G:].
Unless there is conspicuous black uniformity, there is no
need to adjust. (Go to step 7 if no adjustment is required.)
2. Select adjustment point [No. 2] [G:].
When the background is [G] monochrome, press
the [MENU SELECT] key on the Remote control
transmitter to change to solid white.
3. Adjust 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 difference
meter is used, the [
convenient. When adjustment point [No. 1]
color coordinate has been selected, set the
slide switch on the side to [
holding down the [F] button on the front panel.
The measurement shown after this displays
the deviation from measurement point 1.
4. Now measure the color coordinates of measure-
ment point [No. 2] and adjust [No. 2] and [G:] so
that the color coordinates are as follows.
y = y1 0.050 (adjust Y only)
Similarly, measure adjustment points [No. 3] to [No.
9] and adjust their color coordinates starting in
order from the small number points.
5. Then adjust [MAX] tone [G].
Select [No. 2] [G:]. If the background is white solid,
press the [MENU SELECT] key on the Remote
control transmitter to change to [G] monochrome.
6. Measure the illuminance of measurement point
[No. 2] and [No. 3]. Temporarily set [No. 2] to
illuminance Y2 and [No. 3] to illuminance Y3 [lx].

7. Adjust the illuminance of measurement point [No.
2] and [No. 3] to their average values. Thus
illuminance Y2' and Y3' of measurement points
[No. 2] and [No. 3] should be the following after
adjustment.
Y2' = Y3' = (Y2 + Y3)
8. Next, measure the illuminance of measurement
point [No. 10] and [No. 11].
Adjust the illuminance of measurement point [No.
10] and [No. 11] to their average values. Thus
illuminance Y10' and Y11' of measurement points
[No. 10] and [No. 11] should be the following after
adjustment.
Y10' = Y11' = (Y10 + Y11)
This completes [G] color adjustments.
9. Then adjust [MAX] tone [R] and [B].
Select [No. 2] [B:] and press the [MENU SELECT]
key on the Remote control transmitter to change to
solid white.
10.Adjust the color coordinates of adjustment point
[No. 1] and make a note of them.
Assume that they are x = x1, y = y1.
11.Now measure the color coordinates of measure-
ment point [No. 2] and adjust [No. 2] [R:] and [B:]
so that the color coordinates are as follows.
x = x1 0.010, y = y1 0.020
Similarly, measure adjustment points [No. 3] to [No.
9] and adjust their color coordinates starting in
order from the small number points.
