摘要
本文通过对威特ＤＩ２００２测距仪性能的测试。发现影响测距精度的主要因素是ＧＲＴ１０－ＧＰＨ１Ａ的反射镜系统。威特ＤＩ２００２测距仪匹配ＭＥ－３０００反射镜后，需加两项改正，但观测精度显著提高，实测表明达到与ＭＥ－３０００测距仪相同的精度。
By the performance test of the Wild DI 2002 ranger the chief factor, which is GRT10-GPH1A, affecting ranging precision is found out. To the data measured with Wild DI2002 ranger matching of ME 3000 reflector two sorts of corrections, that are due to 1) unequal heights of instrument and reflector,2) the eccentricity of infra-red light axis, are necessary, then the measurement precision will considerably be improved. The field data indicate that this precision reaches the same as with ME-3000.
