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 [
Æ
](delta) mode is
convenient. When adjustment point [No. 1]
color coordinate has been selected, set the
slide switch on the side to [
Æ
](delta) while
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
0.030 (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 measure the color coordinates for adjustment
point [No. 10] and adjust [No. 10] and [G:] so that
the color coordinates are as follows.
y = y1
0.050 (adjust Y only)
Similarly measure adjustment points [No. 11] to
[No. 17] and adjust their color coordinates starting
in order from the small number points.
6 This completes the adjustments required for [MIN].
Note : Since excessive correction may lead to a
correction data overflow during internal
calculations, use the following values for
reference.
[No. 2] to [No. 9]
40 or less
[No. 10] to [No. 17]
70 or less
7 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.
8 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].
9 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) ÷ 2
20 [lx]
10. 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) ÷ 2
20 [lx]
This completes [G] color adjustments.
