摘要
在精密水准测量中,视准轴误差(i角)是必须限制的系统误差。针对目前对数字水准仪电子i角检定概念的误解,论述了数字水准仪电子i角的设置与(剩余)电子i角的检定的异同;明确了各种规范所限定的只是(剩余)电子i角而非电子i角。这对今后制定数字水准仪测量规范具有明确的指导意义。
Collimation error must be limited for precise leveling. Because of misunderstanding the meaning of electronic collimation error in digital level, this paper discusses different schemes for setting and calibration of electronic collimation error. It is the (residual) electronic collimation error necessary for precise leveling and the specifications of leveling standards regulate limits of (residual) electronic collimation error.
