摘要
根据多年电子测量技术课程的教学工作经验,通过对在校生和毕业生的了解,以及对我国电子测量仪器现状的调查,发现技术指标对选择使用和销售购买电子测量仪器至关重要,正确选择测量方案和一定指标的测量仪器能够大大提高测量准确度.基于此,从电压、频率和数字三个方面深入剖析了17个电子测量仪器的常用技术指标.
Aaccording to many years experience in the electronic measurement technology course teaching,to understand the survey of students and graduates,as well as to the study of the current situation of the electronic measuring instruments in China,I found that technical indicators to choose to use and sell the purchase of electronic measuring instrument is very important.The corre-ct choice of measurement scheme and measuring instrument with certain index can greatly improve the accuracy of measurement.I have deeply analyzed the common technical indexes of 17 elec-tronic measuring instruments from three aspects:voltage,frequency and number.
