4.3. Adjustment of White Balance
(for Manual adjustment)
■ Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000
■ Operate the zero-calibration of the CA100+ or CA-210, then
stick sensor to the module when adjusting.
■ For manual adjustment, it is also possible by the following
sequence.
1) Select white pattern of heat-run by pressing “POWER
ON” key on remote control for adjustment then operate
heat run longer than 5 minutes. (If not executed this
step, the condition for W/B may be different.)
2) Push “Exit” key.
3) Change to the AV mode by remote control.
4) Input external pattern (85% white pattern)
5) Push the ADJ key two times (entering White Balance

8) Adjust three modes all (Cool / Medium / Warm) : Fix the
one of R/G/B gain and change the others
9) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
* CASE
First adjust the coordinate far away from the target value(x, y).
1) x, y > target
i) Decrease the R, G.
2) x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3) x > target , y < target
i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R
4) x < target , y > target
i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G
■ Standard color coordinate and temperature when using the
CA100+ or CA210 equipment (Small size inch’s color
coordinate is different from others, So use below table)
