该仪器由 KernEl 经纬仪,DM—501测距仪,固体存储器,以及能显示数字的计算机组成。应用于大坝变形观测中,精度可达±1毫米/公里。现将各部分作简要介绍。模块系统该系统由电子经纬仪,光电测距仪,数字存储器,以及能显示数字的电子计算机等部分模块组成。互相传递讯息,经处理后,能自动显示或储存观测数据(如:水平距离、高差、水平角与竖直角等等)。莫阿干涉纹 The instrument consists of a KernEl theodolite, a DM-501 rangefinder, a solid state memory, and a computer capable of displaying numbers. Applied to dam deformation observation, the accuracy of up to ± 1 mm / km. Now make a brief introduction of each part. Module system The system consists of electronic theodolite, photoelectric range finder, digital memory, as well as to display the number of electronic computers and other modules. Communicate messages to each other, after processing, can automatically display or store the observed data (such as: horizontal distance, elevation, horizontal angle and vertical angle, etc.).
