Note : • Use a reflection type with chart for this adjustment, therefore, control the light so that the white area of chart is exactly 3200K of color temperature.
•If use the pattern box, make sure that the color temperature must be 3200K.
•Usually, this adjustment is not required. Only when the output level of CCD unit is large different from the specification.
•When the new CCD unit of spare parts is replaced, this adjustment is not required because of the correct adjustment at the factory.
