摘要
电位差计是一种精确度很高的测量仪器,但用它进行测量的过程中,仍然会产生误差。本文利用电位差计的工作原理,介绍了几种误差因素的产生及消除的方法。
The voltage difference meter is a surveying instrument which is quite precise, But in the process of measuring, errors may still exist. This essay introduces the reasons of the production of errors and the method to remove errors according to the operation philosophy of the voltage difference meter.
