8. Adjustment of White Balance
Caution: Press the POWER ON KEY on R/C before W/B adjustment.
8-1. 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-1000 and adjust
in accordance with White balance adjustment coordinate.

8-2. Connecting Picture of the Measuring 
Instrument
(On Automatic control )
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push control R/C ADJ Key—> Enter the
mode of White-Balance, the pattern will come out.
8-3. 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) In case of PDP: Measure and adjust after sticking the Color
Analyzer (CA-100+, CA210) to the side of the module. 
In case of LCD: 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  
1) After aging start, keep the power on (no suspension of
power supply) and heat-run over 15 minutes.
2) In case of PDP, keep white pattern using inside pattern.
3) In case of LCD, using ’no signal’ or ‘full white pattern’ or
the others, check the back light on.

8-4. Manual White Balance 
(1) Press the POWER ON KEY on R/C for adjustment and
heat run over 5 minutes.
(2) Zero Calibrate CA-100+ / CA-210, and when controlling,
stick the sensor to the center of PDP module surface.
(3) Press the ADJ KEY on R/C and enter EZ ASJUST
Select “3.W/B ADJUST” and press ENTER(
V
)
Set test-pattern on and display inside pattern. 
(4) Control is carried out on three color temperatures, COOL,
MEDIUM, WARM.(Control is carried out three times)
<Temperature: COOL>
- R-offset / G-offset / B-offset is set to 128
- Control R-Gain and G-Gain.
- Each gain is limited to 192
<Temperature: MEDIUM>
- R-offset / G-offset / B-offset is set to 128
- Control R-Gain and G-Gain.
- Each gain is limited to 192
<Temperature: WARM>
- R-offset / G-offset / B-offset is set to 128
- Control G-Gain and B-Gain.
- Each gain is limited to 192
