该垂直水平电子检测仪,具有设计新颖、光电指示及精确度高等特点。由于它采用发光二极管显示,所以最适合于在无光照条件下使用。该装置电路工作原理见图1,V_1、V_4为红外发射接收对管,S_1为电源开关,S_2为垂直水平度检测转换开关(S_2置于A时为水平度检测,置于B时为垂直度检测)。红外发射接收对管和平衡锤摆装在如图2所示支架上,将红外接收对管与平衡锤的透光小孔调在
The vertical level of electronic detector, with a novel design, photoelectric instructions and high accuracy. Because it uses light-emitting diode display, so the most suitable for use in the absence of light conditions. The working principle of the device circuit is shown in Fig. 1, V_1 and V_4 are the infrared transmitting and receiving tubes, S_1 is the power switch, S_2 is the vertical level detecting switch (S_2 is horizontal when B is set to A, Test). Infrared emission receiver tube and balance weight mounted on the bracket shown in Figure 2, the infrared receiver on the tube and the balance of light translucent holes transferred to
