At contrast control set at maximum level, adjusting brightness control from minimum setting to
maximum setting, the light output of 3” block pattern should be increased more than 15 dB.
If both brightness and contrast control are minimum, the 3” block should be extinguished.
1.4.1.6 Linearity ( set to 20 Ft-L at full white pattern first) 10x8 crosshatch pattern:
(1) Vertical Non-linearity 5 % max, as Fig.1. Formula :
Ymax - Ymin
Ymax + Ymin
X 100% < 5%
(2) Horizontal Non-linearity 5 % max, as Fig.1. Formula
:
Xmax - Xmin
Xmax + Xmin
X 100% < 5%
