IS-Inch and 19-Inch Color Monitor Display Centering
The display must be centered on the CRT face within 6 mm horizontally. The measurement is done by taking a differential between A and B. The differential must not exceed 6 mm. The vertical display shall be centered on the CRT within 6 mm. The measurement is done by taking a differential between C and D.
The yoke rotational error must not exceed 1 degree maximum.

IS-Inch Color Monitor Available Brightness Conditions:
Display Area 8
Outline of the phosphor area or bezel edge
1. Full white field of 100% duty cycle displayed, with a signal input amplitude of 714 millivolts from blanking level to reference white level.
2. Brightness control at center position.
3. Contrast control at maximum clockwise position.
The light output as measured at center screen must be 12.5 FL minimum and 25 FL maximum. No back-ground raster is acceptable with the brightness control in the center position. When the contrast and brightness control is rotated to its maximum counterclockwise position, the light output must be no more than 5 FL. The minimum to maximum brightness ratio is calculated as follows:
MAXIMUM BRIGHTNESS
--- equal to no less than 2.5 to 1 MINIMUM BRIGHTNESS
Measured between the center and corners of the CRT, there must be no more than a 50% decrease in light output at anyone corner.
19-Inch Color Monitor Available Brightness Conditions:

The light output as measured at center screen must be 9 FL minimum and 14.5 FL maximum. No back-ground raster is acceptable with the brightness control in the center position. When the contrast and brightness control is rotated to its maximum counterclockwise position, the light output must be no more
than 5 FL. The minimum to maximum brightness ratio is calculated as follows: c:~\

1S-Inch and 19-Inch Color Monitor Color Temperature
The color temperature must be adjusted to 9300 0 C + 27 MPCD as represented by the X and Y chromaticity coordinates of X = 0.281 and Y = 0.311 (± 5%). The reference instrument is a Color Ana-lyzer II by Minolta. All controls used to set color tracking and cutoff must be 'factory sealed.
1S-Inch and 19-Inch Color Monitor Tracking
From maximum brightness output to minimum brightness output, no single color should achieve domi-nance. If questionable, the measurement must be done at 5 FL of brightness and be within the range for the X and Y coordinates for 9300 0 C (± 7%).
1S-Inch Color Monitor Display Area
The display area of the monitor should be 267 mm x 200 mm (± 5 mm) at rated timing.
19-Inch Color Monitor Display Area
The display area of the monitor should be 346 mm x 259 mm (± 5 mm) at rated timing.
1S-Inch and 19-Inch Color Monitor Aspect Ratio The display must achieve an aspect ratio of 4:3.
1S-Inch and 19-Inch Color Monitor Emission Warm-Up Time The emission warm-up time must be less than 20 seconds.
1S-Inch and 19-Inch Color Monitor Drift
The monitor must operate over the specified temperature range (0 0 C to 500 C) without losing synchroni-zation or any visible change in light output. No manual adjustments shoul,d be necessary over the specified temperature range.
