4.1. White Balance adjustment
▪ W/B Equipment condition
CA210 : LED -> CH14, Test signal: Inner pattern(80IRE)
▪ Above 5 minutes H/run in the inner pattern. (“power on” key
of adjust remote control)
▪ If it is executed W/B adjustment in 2~3 minutes H/run, it is
adjusted by Target data.
(For OS LED / Direct LED module)
▪ Normal line
* Aging chamber
* 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.
