由中国计量科学研究院研制的经纬仪综合检测装置，不久前在北京通过专家鉴定。该标准装置首次利用奇数齿卧轴式多齿分度台作为竖直角标准分度元件，能多测点组合自检，所用元件少，误差传递链短，准确度高，稳定性及可靠性好，使用寿命长。该装置特点：由于设计了W－Z光学转换 By the China Institute of Metrology developed theodolite integrated detection device, not long ago in Beijing by experts. The standard device for the first time using odd-tooth horizontal axis multi-tooth indexing station as a vertical angle standard indexing device, can test multiple combinations of self-test, the components used, the error transmission chain is short, high accuracy, stability and reliability Good, long service life. The device features: Due to the design of the W-Z optical conversion
