(On Automatic control)
Inside Pattern is used when W/B is controlled. Connect to
auto controller or push Adjustment Remote control POWER
ON → Enter the mode of White-Balance, the pattern will
come out.
Full White Pattern
RS-232C Communication

* 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
y
less than 10 cm distance, keep it with the surface of the
329
Module and Color analyzer's prove vertically.(80° ~ 100°).
348
(3) Aging time
346
- After aging start, keep the power on (no suspension of
343
power supply) and heat-run over 5 minutes.
339
- Using 'no signal' or 'full white pattern' or the others,
check the back light on.
