(3) Message as shown below can be verified after completion
of adjustment, and readjust following the (2)(3) step if
"Fail" occurs.
"OK" : White Balance Process Successful and Warm, Cool
chromaticity diagram is within the target.
"Fail" : White Balance Process Failure -> Execute
readjustment.
"Warm Fail" : White Balance Process Successful and
Warm chromaticity diagram deviated more
than 0.005 from the target.
"Cool Fail" : White Balance Process Successful and Cool
chromaticity diagram deviated more than
0.005 from the target.
"Warm and Cool Fail" : White Balance Process Successful,
(4) For verification of White Balance adjustment results, press
ADJ Key and enter "4. DDP Manual CCA". (Fig. 10-3-2)
(Fig. 10-3-2) Selection Category on INSTART Menu (Left)
(Fig. 10-3-3) Menu after entering Manual CCA (Right)
(5) Read the coordinate of CL200 changing the Color Temp
Mode to Medium, COOL, Warm for checking the Spec of
each mode.
- Warm Mode : x = 0.313 ± 0.004, y = 0.326 ± 0.004
- Cool Mode : x = 0.283 ± 0.004, y = 0.297 ± 0.004
- If it goes over the deviation boundary with the value of
0.005, it has no problem. During Auto CCA, it becomes
OK only when it comes within the above deviation
boundary. Afterwards, if it goes out of the boundary a
little bit when it is checked with a manual CCA, it can be
judged as a deviation due to meter/environment. (Only for
Warm Mode and Cool Mode)
