2) Read the value of the luminance meter. x=0.272, y =0.277
3) Change MG6R/MG6B (Adjustment offset value) on page 14/33 of process adjustment so that the values of the luminance meter approach x=0.272
and y =0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R and B must be fixed.)
4) Display the adjustment status of the current point 5. (Each time the “5” button on the remote control is pressed, the adjustment status check dis-
play is toggled.)
