Connecting picture of the measuring instrument
(On Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C POWER-ON -> Enter
the mode of White-Balance, the pattern will come out.
●
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 ‘full white pattern’ or the others, check
the back light on.
