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 X = 0.283 0.020
Y = 0.297 0.020
6500 K CIE coordinates X = 0.313 0.020
Y = 0.329 0.020
5500 K CIE coordinates X = 0.332 0.020
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
The color coordinate at any point on the screen should be :
X = X (center) 0.015
Y = Y (center) 0.015
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:
x = x (center) +/- 0.015
y = y (center) +/- 0.015
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
Remark: If the external degaussing is used, the degaussing coil should be a stick type,
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.
