本程序适用于三、四等水准及等外水准的观测记录工作。观测程序可以是后前前后,亦可后后前前。距离测量可以是读上、下丝,亦可直读距离。高差的观测可以是不改变仪器高,亦可改变仪器高进行观测。各观测数据全部采取汉语拼音式的人机对话形式输入。误差超限时,计算机报警并显示误差值后自动要求重测。 This procedure applies to three, four and other levels of observation and recording of the work. Observation procedures can be before and after, but also before and after. Distance measurement can be read on, off the wire, but also direct reading distance. The elevation of the observation can not change the instrument height, the instrument can also be changed to observe the high. All observations were taken using Chinese pinyin dialogues. When the error exceeds the limit, the computer will automatically request a retest after the computer alarms and displays the error value.
