11. Adjustment of White Balance
11-1. Requirement
V
Before adjusting White-balance , the AV ADC should be
done.
11-2. Required Equipment
1) Remote controller for adjustment.
2) Color Analyzer.( CA-1000,CA-100+,CA-200 or same
product ) : CH10(PDP)
* Please adjust CA-210, CA-100+ by CS-1000 before
measuring.
3) Auto W/B adjustment instrument.(only for Auto adjustment)
4) AV Pattern Generator. 
Synchronization relation between PSM and CSM.
CS-1000/CA-100+/CA-210 White balance adjustment coordinate
and color temperature.
11-3.  Connection Picture of the Measuring
Instrument(On Automatic control)
V  
Inside PATTERN is used when W/B is controlled. Connect
to auto controller or push control R/C IN-START -> 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. Measure and adjust after sticking the Color Analyzer(CA-
100+, CA210) to the side of the module.
3. Aging time : keep white pattern using inside pattern.

12. Adjustment of White Balance
(Manual white Balance)
V  
One of R Gain/ G Gain/ B Gain should be kept on 80, and
others are controlled lowering from 80
(1) ‘power on’ of the control R/C, set heat run to white by
pressing and heat run over 15 minutes. (Set: RS-232 Host:
PC, Baud Rate: 115200bps, Download: Cortez) 
(2) Zero Calibrate CA-100+, and stick the sensor to the center
of PDP module surface when you adjust.
(3) Double click In-start key on Controlling R/C and get in
‘white balance’.
(4) Set test-pattern on and display inside pattern. Control is
carried out on three color temperature, COOL, MEDIUM,
WARM. (Control is carried out three times.)
(5) When the R/G/B GAIN is 80 on OSD, it is the FULL
DYNAMIC Range of the Module. In order to control white
balance without the saturation of FULL DYNAMIC Range
and DATA, one of R Gain / G Gain / B Gain should be kept
on 80, and other two is controlled lowering from 80.
* Color Temperature: Cool, Medium, Warm
(1) When R GAIN is set to 80
- Control G GAIN and B GAIN by lowering from 80. 
(2) When B GAIN is set to 80
- Control R GAIN and G GAIN by lowering from 80.
(3) When G GAIN is set to 80
- Control R GAIN and B GAIN by lowering from 80.
One of R Gain / G Gain / B Gain should be kept on 80, and
adjust other two lower than 80.
(When R/G/B GAIN are all 80, it is the FULL DYNAMIC
Range of Module)
