- Before adjusting White-balance , the AV ADC should be done.
- If ADC status were “NG”, Need to ADC adjustment.
- If ADC status were “NG”, Need to ADC adjustment.
14. Adjustment of White Balance
Caution: Press the POWER ON KEY on R/C before W/B
adjustment.
14-1. Test Equipment
- Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))
[
Please adjust CA-100+ / CA-210 by CS-1000 before
measuring
--> You should use Channel 10 which is Matrix
compensated (White, Red, Green, Blue revised) by CS-
