ANALYZER

TYPE: CA-210

RS-232C Communication

*Auto-control interface and directions

1)Adjust in the place where the influx of light like floodlight around is blocked. (illumination is less than 10 lux).

2)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.(80º ~ 100º).

3)Aging time

-After aging start, keep the power on (no suspension of power supply) and heat-run over 15minutes.

-Using ‘no signal’ or ‘full white pattern’ or the others, check the back light on.

*After done all adjustments, Press “In-start” key and compare Tool option and Area option value with its BOM, if it is correctly same then unplug the AC cable. If it is not same, then correct it same with BOM and unplug AC cable. For correct it to the model’s module from factory Jig model.

*Push the “IN STOP” key after completing the function inspection. And Mechanical Power Switch must be set “ON”.
