Adjustment procedure 1
(when a color differential meter is used)
1. First adjust [MID-L] tone [G:].9. Similarly, measure adjustment points [No.3] to

The values should be: [No.2] to [No.5] ? 40 or less
No.2 = Y2 [lx] No.10 = Y10 [lx] [No.6] to [No.9] ? 50 or less
No.3 = Y3 [lx] No.11 = Y11 [lx] [No.10] to [No.13] ? 70 or less
