White balance and cutoff adjustment system
This is PC software created using standard accessory software CA-SDK and
others, and it controls the display drivers such as CA-100Plus and pattern
generator to measure the white or black luminance.
The white and black correction coefficients are obtained from the measured
luminance values of the display, and they are written to the correction circuit of
the display.

Display sample
You can select the "CA-100-compatible mode" and the
"CA-200 mode" with the CA-100Plus. In the CA-100-
compatible mode, compatibility with the measurement
data of CRT color analyzer CA-100 and compatibility with
the RS-232C communication environment of the CA-100
are obtained, and in the CA-200 mode, standard
accessory software CA-SDK can be used.
CA-100Plus is for those who already have CA-100 and
who want to maintain data compatibility, or for those who
have
including CA-100 and who intend to use the new analyzer.

User's own matrix correction factor is set to the memory
channels by measuring three monochrome colors (R, G,
B and W) of known values and setting the obtained
calibration values (xyLv) and emission characteristic to
the instrument. Once this factor is set, the measured
values will be displayed after correction by this factor and
output each time measurement is taken.
Performing matrix calibration enables high-accuracy
measurements of displays that provide colors through

additive color mixing of three monochrome colors (R, G
made with SDK
and B).
Since the matrix correction factor obtained from Minolta's
calibration standard has been set, measured values
calculated based on this factor will be acquired when this
instrument is used for the first time since shipment from
the factory.
CA-SDK
Cal
CA-100Plus is corrected in the matrix calibration method
using Konica Minolta's spectroradiometer CS-1000A.
Color
The measurement data of CA-100Plus is acquired into
the PC.
Drift tests, repeatability test and so on can be performed
easyly. The acquired data can be read with EXCEL
other spreadsheet software.
Contrast
Multi-point measurement (5, 9, or 25 points) is made for
white uniformity measurement.
