本标准推荐用于A型脉冲反射式超声探伤仪示波管上,为便于读取显示波形的位置和幅度而设置的通用刻度板。 1 名词术语 a.刻度板在示波管前面具有刻度的板。其纵、横轴均以等间隔或按一定的比例进行刻度。 b.满刻度用刻度板的纵、横轴的直线段表示的整个范围。 2 技术要求 2.1 满刻度满刻度是由所使用的示波管的荧光屏有效尺寸得到的长方形的各边长度决定的,纵、横之比为0.6～
This standard is recommended for A-type pulse reflection ultrasonic flaw detector oscilloscope tube, in order to facilitate the display waveform display position and amplitude and set the common scale. 1 Terminology a. Scale plate The scale in front of the oscilloscope board. The vertical and horizontal axis are equal intervals or according to a certain scale. b. full scale with the vertical and horizontal axis of the scale of the entire range. 2 Technical Requirements 2.1 full scale Full scale is determined by the length of the sides of the rectangle obtained by the effective size of the screen of the CRT used, the ratio of vertical to horizontal is 0.6 ~
