These tubes shall be operated at standard operating conditions with 5 microamperes direct current applied to each gun for a period of 48 hours. During this 48 hour period, the tube shall be turned off for 30 minutes (allo

Visual inspections shall be made to ensure that all JAN 7YP2 CRTs are failure free from arcing for continuous and intermittent o
7、perational testing during all manufacturing and acceptance testing. Pressure test method 1141 shall be performed, except 30 pounds per square inch (PSI) absolute pressure shall be applied in lieu of 45 PSI absolute, on a 100 percent basis prior to shipment for the JAN 7YP2 tube only. Only those tube

Operation at other ratios of Eb3/Eb2 may result in changes in deflection uniformity and pattern distortion
25、. 3. All tests except direct-interelectrode capacitance, vibration and interaction factor, shall be made on each unit separately. Each deflection plate shall be connected to A2 through a resistance of 1 M 10%. 4. All other electrodes contained within the envelope are to be tied together. 5. This tes
26、t shall be performed during the initial production and once each succeeding 12-calender months in which there is production. A 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 inspectio
27、n, part 2, with an Acceptance Level of 6.5 (see note 16). The regular “12 calendar month” sampling plan shall be reinstated after three consecutive samples have been accepted. 6. The pattern size shall be adjusted to 1.5 inches (38 mm) in the limited scan direction. 7. Due to limited scan of 3D4 pla
28、tes, the length of scan in the 3D4 direction shall be limited to 1 inch from the undeflected spot position. Line width “B” shall be measured at 0.75 inch ( 19.1 mm) from the undeflected spot position. 8. From the spot positions as indicated on figure 1. Provided by IHSNot for ResaleNo reproduction o

The deflection in this direction covers the minimum useful screen width following the bulb contour. 10. The deflection in this direction is limited to 0.75 inch ( 19.1 mm) minimum from
30、 the undeflected spot position. 11. This test to be performed at the conclusion of the holding period. This test applies only when P1 CRT screen phosphors are specified. 12. Corresponding traces of each unit are to be within 2 degrees of each other. 13. This test is not required unless specified in
31、the purchase order or contract. 14. The tube manufacturer (7YP2 only) shall provide the user with two years of service life warranty commencing with shipment from the tube manufacturer. The second year of this warranty shall be pro-rated. Other terms and agreements regarding this warranty (i.e., pro
32、-rating, handling of defectives) shall be negotiated at the time of purchase. The appropriate applicable documentation shall be provided by the tube manufacturer and this documentation shall accompany the tube. The user will be responsible for completing and returning the documentation to the manufa
