Auto-control interface and directions
1. Adjust in the place where the influx of light like floodlight around is blocked. (Illumination is less than 10ux).
2. Adhere closely the Color Analyzer ( CA210 ) to the module less than 10cm 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 heat-run over 5 minutes.
-. Using ‘no signal’ or ‘POWER ONLY’ or the others, check the back light on.
-. Using ‘no signal’ or ‘POWER ONLY’ or the others, check the back light on.
