2) Four views of the cathode ray tube are required, namely: front view, long side view, short side view and diagonal view (diagonal view may be omitted if all the required data can be given by other means), 3) Reference lines are determined using appropriate reference line gauges. 4) This data cannot be measured and is for user reference only, 5) The position of each side electrode cap is specified in the following way: a. Mark the distance from the center of the panel (nominal ±) b. Indicate the angular deviation that the plane through the side electrode panel and the tube axis can deviate from the beam track produced by a specified pair of deflection electrodes, or from the plane through a specified tube pin,
C. Indicate on which side of the cathode ray tube the side electrode cap is located relative to the specified tube pin. 6) Specify the position of the side electrode cap by the following method: a. Mark the distance from the reference line (nominal ±); b. Indicate the angular deviation of the plane passing through the side electrode cap and the tube axis from the plane passing through the tube axis and the specified tube pin (or empty pin position): °C.Indicates on which side of the cathode ray tube the side electrode cap is located relative to the specified pin (or empty pin position). 7) Specifies the minimum size of the orientation and contact surface relative to the side electrode cap. 8) When the required type and data are not given in GB787, GB3189, GB11484 standards, the corresponding dimensions should be marked with reference to these standards. 9) The axis of the tube neck is specified as the line passing through the centers of the two specified planes of the tube neck. 10) It is required to specify the orientation of the scale axis relative to the deflection axis. 11) The center of the mounting bolt should be located at the four vertices of the rectangle formed by the two radial distance heights, and the bolt of the specified diameter should be able to pass through the fixing ear hole. 3 Legend
