COLOR
ANALYZER
TYPE :
*Auto-control interface and directions
(1)Adjust in the place where the influx of light like floodlight around is blocked. (illumination is less than 10 lux).
(2)Adhere closely the Color analyzer(CA210) to the module less than 10 cm distance, keep it with the surface of the Module and Color analyzer's prove vertically.(80° ~ 100°).
(3)Aging time
-After aging start, keep the power on (no suspension of power supply) and
-Using 'no signal' or 'POWER ONLY' or the others, check the back light on.
