Then output from the horizontal and vertical circular encoders and from the EDM can be displayed at the instrument and stored in a data collector and enters into a built-in microprocessor. The microprocessor can convert the measured slope distance to the horizontal distance using the measured vertical or zenith angle. The microprocessor also computes the difference in elevation between the instrument center and the prism target. 译文：然后从水平和垂直度盘编码器与从电磁测距仪中的输出数据能被显示在仪器上和存储在一个数据采集器中,从而可以导入到一个内置的微处理器。这个微处理器能够把测得的斜距利用测得的垂直角或天顶角转换成水平距离。这个微处理器也可以计算仪器中心到棱镜目标间的高差。 Notes to the Text 2. Furthermore the microprocessor can also compute the resolution of the horizontal distance together with the current horizontal direction, expressed as an azimuth, into a coordinate of the target station. In construction layout measurement, the data necessary to establish the direction and distance from a control point to locate a construction point can be entered into the instrument via the keyboard or directly from an office computer. 译文：此外，微处
