Table 5: Reading with Konica Minolta CS-200.
Note:
1. Use Konica Minolta CS-200. for color coordinates and luminance check.
2. For suitable mass production at factory, colour analyzers CA-210 can be applied. But, befor measureing ,all CA-210 should be coordinates
and proofread with a Charoma Meter (CS-200) or equivalent instrument and a reference TV set.
3. Check the luminance in the center of the screen with 100% White. And to Brightness control at 100; Contrast control at 100
