摘要
论述了数字水准仪的基本特点,基于这些特点将数字水准仪主机、条码尺和数据处理软件作为一个整体进行系统检定是一种恰当的方法。文中给出了系统检定的原理、测点数及位移量的确定方法。最后用模拟数据进行了计算,模拟计算结果表明:正确的位移量是求解尺度改正数的前提。
This paper describes the property of digital level. Based on the property,it is a suitable method to calibrate the digital level and the bar staff as measuring system. This calibration method is called system calibration. The author gives the principle of system calibration. The importance of choosing the sampling interval and the number of measuring points is confirmed by using analogue measuring data.
