基本数据采集系统是由计算机、数据采集控制装置和一次仪表等三部分组成的(如图1所示)。要提高数据采集系统的测试精度,就必须减小其各种可能产生的误差。而数据采集系统的误差主要包括数据采集装置的误差(包括装置本身误差及干扰引起的误差)和一次仪
The basic data acquisition system is composed of three parts: computer, data acquisition and control device and a meter (as shown in Figure 1). To improve the data acquisition system testing accuracy, it must reduce its various possible errors. The error of the data acquisition system mainly includes the error of the data acquisition device (including the error caused by the device itself and the error caused by the interference) and the primary instrument
