The light output shall be set at 2 fL. The high-frequency scanning shall be applied to the deflecting plates n
26、earest the screen and the amplitude shall be adjusted to give a line length of approximately 90 percent of the maximum tube diameter. The low-frequency scanning amplitude shall be expanded to approximately 90 percent of the maximum tube diameter in the direction perpendicular to the direction of the
27、 high-frequency scanning. Readjustment may be made for best overall focus. The tubes shall be observed for deflection defocusing, astigmatism, or spot ellipticity observable to the eye as evidenced by fuzziness due to lack of sharpness of trace (usually around edges), bow-tying (irregular widths of
28、any single line when observed at different points), bowing of trace other than that normally caused by curvature of bulb. This test for focus is to be made in addition to the line width measurements. 2. The same conditions shall be set up as described in note 1 except that the connection of deflecti
29、ng elements to the low- and high-frequency scanning supplies shall be interchanged and the amplitudes adjusted to 90 percent of the maximum tube diameter in both directions without any adjustment of focus from note 1 conditions. An examination for defocusing, astigmatism, or spot ellipticity shall b

As measured with a 2x2 inch raster using a type 3 Photronic cell without eye correction, calibrated in foot candles of illumination from a light source having a color temperature of 2,700 K. 4. This test shall be performed during the initial production and once each succeedin
31、g 12-calender months in which there is production. An accept on zero defect sampling plan shall be used, with sample of three tubes with an acceptance number of zero. In the event of failure, the test will be made as a part of conformance inspection, part 2, with an acceptance level of 6.5 (see note
32、 5). The “12-calender month” sampling plan shall be reinstated after three consecutive samples have been accepted. 5.
