The Fourth Machine Industry Department of the People's Republic of China Standard Electron Beam Tube Screen Scale
SJ2130-82
This standard specifies the size specifications, technical requirements, codes and color selection rules for the electron beam tube screen scale. This standard is applicable to the screen scale of electron beam tubes such as oscilloscopes, indicating tubes, and intuitive storage tubes. Definitions of related terms
1.1 Screen scale
Scale scale is made directly on the inner surface of the fluorescent screen (referred to as internal scale). 1.2 Scale scale
Scale pattern with certain size specifications and line width. Codes for internal scales
2.1 Composition of internal scale codes
The codes for internal scales are composed of Arabic numerals and Latin letters. The numerals represent the size specifications of the internal scales, and the letters represent the colors of the internal scales.
The colors represented by letters are as follows
a: "A" represents grayish white or white, b. "B" represents black;
c. "C" represents red;
d. "D" represents orange.
2.2 Principles of unchanged internal scale codes
When the basic size specifications and color of the internal scales remain unchanged, and only the details of adding or removing text, symbols, percentage lines, extending the axis and disconnecting the scale lines on the scale table need to be changed, the codes for the internal scales remain unchanged. 3 General rules for selecting the color of the internal scales
3.1 The screen luminous color is green, the afterglow color is green (J-type tube), and black, red, grayish white or orange can be selected. 3.2 If the screen luminous color is blue and the afterglow color is blue (A-type tube), choose grayish white or white. 3.3 If the screen luminous color is white and the afterglow color is orange (D-type tube), choose black or red. Note: Grayish white or white internal scale is used in the case of edge lighting. Technical requirements for internal scale
4.1 The lines of the internal scale should be clear, and the line width and color should be uniform. 4.2 The non-perpendicularity between the horizontal scale lines and the vertical scale lines of the internal scale should not be greater than ±0.3. 4.3 The spacing between two adjacent lines of the internal scale and the deviation of the full-length size from the nominal size should not exceed ±1% of the original nominal size. 4.4 The deviation between the symmetry axis of the internal scale and the symmetry axis of the screen should not exceed ±2°. 4.5 The deviation between the center of the internal scale and the geometric center of the screen should meet the following requirements: a. If the diagonal (or diameter) of the screen is 16cm or more, the deviation value should not be greater than 1mmb. For screen diagonal (or diameter) of 16cm or more, the deviation value shall not be greater than 2mm. The Fourth Ministry of Machinery Industry of the People's Republic of China issued on October 4, 1982 and implemented on January 1, 1983
SI2130-82
4.6 The deviation of the line width of the center part of the inner scale shall not be greater than ±30% of the nominal line width; the deviation of the line width of the four corners of the inner scale shall not be greater than ±50% of the nominal line width. The area within the circle with the inner scale symmetry center as the center and 90% of the length of the long axis as the diameter is the "inner scale center"; the area outside the circle is the "inner scale four corners" 4.? If there are several line widths in the same scale, the ratio of the widest to the narrowest line width shall not be greater than 3. 4.8 The quality requirements for the disconnection defects of the inner scale lines shall comply with the provisions of Table 1.
