Minolta CA-100 CRT Color Analyzer
for automation of CRT production lines
The Minolta CRT Color Analyzer CA-100 is an
easy-to-use instrument for white-balance adjustment on CRT production
lines, with color measurement and analyzer' functions plus
data-communication capabilities.
The Minolta CRT Color Analyzer CA-100 was
designed to upgrade the white-balance process on production lines for
color TV sets and computer color monitors in the CRT industry. The
multi-function CA-100 reduces the time required for white balance
adjustment and inspection, and provides numerical values for white-balance
control. It is even equipped with data-communication capabilities,
allowing it to become part of a computerized quality-control system or
even a fully automated production line. Continuing advances in consumer
televisions, such as higher reliability, higher image quality, larger
screens, and more features, plus the increased used of high-fidelity
computer color monitors in image-control applications, make the
color-reproduction characteristics of CRTs increasingly important. To
ensure accurate color reproduction, white-balance adjustment must be
performed utilizing a high-accuracy, high-reliability instrument: The
Minolta CRT Color Analyzer CA-100 . With a variety of internal features
plus a wide range of optional accessories to provide additional functions,
the CA-100 can be used to speed up white-balance adjustment and inspection
of many different kinds of CRTs. In addition, data communication and
measurement control can be performed via an RS-232C or GP-I6 system,
making it possible to use the CA-100 on a fully automated production line.
Applications:
-
White-balance adjustment and inspection
on CRT production lines
-
Quality control and shipping inspection
by CRT manufacturers
-
Receiving inspection of CRTs by
computer manufacturers
Features:
-
Wide luminance measurement range of
0.20 to 999cd/m2; (0.06 to 292 fL) allows measurement of
virtually any CRT. Luminance units of cd/m2 or fL can be changed by
the user.
-
Different memory channels (11 standard;
expandable to 100 with optional card) can be used to store calibration
values or standard colors for different CRT types. Each channel can be
labeled with a 10-character ID name for easy identification.
-
Measurements can be displayed as xyY
(colorimetric coordinates, luminance) or T 4uvY (correlated color
temperature, color difference from blackbody locus, luminance) values.
Measured values are displayed both digitally and on LED analog scales.
-
Range of LED analog display scales can
be set by the user between 0 .1 and 99%.
-
A standard RS-232C interface is built
into the CA-100 for outputting data to a separate computer or
controlling the CA-100 from the computer.
Any of four different synchronization modes
can be selected to match the vertical scanning frequencies of different
CRT systems
