论测距精度及仪器常数

Discussion on the Precision and Constant of EDMI

电磁波测距仪的加常数和乘常数这两个概念在使用中引起了混乱,不少人混淆了测距精度与仪器常数的概念,混淆了常数和误差的概念,因而掩饰了仪器检验中的错误,致使用户不能正确计算测距成果。文章澄清了测距精度和仪器常数的概念,笔者认为测距精度不能与仪器常数混为一谈。

There is a confusion canceling the additive constant and multiplication constant of a EDMI. Quite number of people have mixed the concept of the accuracy of measured distance with the instrument constant, and therefore can not correctly calculate the final results. In this paper the two concepts are clarified.
