GENERAL PRODUCT SPECIFICATION
4.15 White color adjustment
There are three factory preset white color 9300°K, 6500°K and 5500°K.
Apply full white pattern, with brightness in 50 % position
and the contrast control at max. position.
The 1931 CIE Chromaticity (color triangle) diagram (x,y)
coordinate for the screen center should be:
9300°K CIE coordinates
Y = 0.297 ± 0.020
6500°K CIE coordinates
Y = 0.329 ± 0.020
5500°K CIE coordinates
Y = 0.347 ± 0.020
4.16 White uniformity
Set the brightness control at center 50 % position, then adjust the contrast
control to set the luminance at the center of the screen being in the range
of 20 - 22 ft-lb. The color coordinate at any point on the screen should be :
4.17 Color tracking on full white pattern
Adjust the contrast control from max. to min.(with brightness at click
position). The color coordinates should not deviate more than:
4.18 Purity
Conditions: With full color pattern, with brightness
control at 50 % position and contrast control in
maximum, under the specific destinations of earth
magnetic environments.
After a warm-up time of 30 min., the purity control can be used to eliminate
colored stains if it occurs, the monitor should be well degaussed before purity
adjustment.
can't use ring type for MITSUBISHI NF CRT.
To set the electrical current of four corner purity coils and N/S coil (if exist)
equal to zero, or switch off the monitor before external degaussing.
