Minolta CA-210
2) Conditions of the set for adjustment and inspection
Modulated light: MAX (+16)
3) A set needs to be ageing for 30 minutes or more.
4) Set a luminance meter to middle of the screen.
2. [Method of the adjustment]
1) In the adjustment process mode, Display the screen of “DVP2-1” on the DVP layer page 1.
It is confirmed that IN6 and IN5 are displayed in default value IN6=204 and IN5=102.
2) White balance adjustment adjusts the adjustment value of point 6 and point 5 R/G/B in the layer page 2 “DVP2-2” of DVP. Point 4 to Point 1 are
not adjusted this time.
3) In the adjustment process mode, Display the screen of “DVP2-2” on the DVP layer page 2.
4) Set standard value G6 of point 6 in “816”.
5) Read the value of the luminance meter.
6) Make R6 and B6 variable by 4 units to the negative direction then adjust, so that the values of the luminance meter approach x=0.272 and y
=0.277.
7) Set standard value G5 of point 5 in “408”.
8) Read the value of the luminance meter.
9) Make R5 and B5 variable by 4 units in the negative direction then adjust, so that the values of the luminance meter approach x=0.272 and y
=0.277.
