本文从应用的角度出发,结合生产实际,介绍测量误差的基本知识,以帮助克服在使用与维护仪表中的某些盲目性。一、误差与仪表的精度等级被测参数的测量值与其真实值之差称为误差。误差是在各种测量工作中产生的。为了测量各种物理量、化学量,以取得各种必要的技术数据,就要使用各种仪器去对这些量进行实测。由于: 1.测量工作环境不断变化,如温度、湿
This article from the application point of view, combined with the actual production, introduced the basic knowledge of measurement error to help overcome some of the blindness in the use and maintenance of the instrument. First, the error and the accuracy of the instrument level The measured parameter measured value and the difference between the true value is called the error. The error is generated in a variety of measurement work. In order to measure a variety of physical and chemical quantities to obtain the necessary technical data, a variety of instruments are used to measure these quantities. As: 1. Measuring the changing working environment, such as temperature, humidity
