(For Manual adjustment)

(1) Color analyzer(CA100+, CA210) should be used in the

calibrated ch by CS-1000.

(2) Operate  the  zero-calibration of the CA100+ or CA-210,

then stick sensor to the module when adjusting.

(3) 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 15 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 -> Enter “0000” (Password)
6) Select “3. W/B ADJUST”
7) Enter the W/B ADJUST Mode
8) Stick the sensor to the center of the screen and select

the one of R/G/B gain and change the others

11) When adjustment is completed, Enter “COPY ALL”.
12) 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

(4) Standard color coordinate and temperature when using the

CA100+ or CA210 equipment
