电子仪表测量技术中日常维护和故障检测

Analysis Of Electronic Instrument Measurement Technology And Daily Fault Detection And Maintenance

万用表的基础功能只有四种:测通断、测电阻、测电压、测电流。其中电压电流又可分为直流电压、交流电压和直流电流、交流电流。如此一来,我们就得到了6种功能,体现在数字万用表的表盘上,就是6个功能区。电子线路故障在电力电子设备故障中是最为常见的一种,会呈现不同的表型形式,文章探讨下电气设备电子线路故障原因和相应的维修办法,并提出有效地预防措施。

There are only four basic functions of the multimeter:measuring and breaking,measuring resistance,measuring voltage,and measuring current.The voltage and current can be divided into DC voltage,AC voltage and DC current,AC current.In this way,we have got six functions,which are reflected on the dial of the digital multimeter,which is six functional areas.Electronic circuit faults are the most common type of power electronic equipment failure,and will present different phenotypic forms.This paper first discusses the causes of electrical equipment electronic faults and corresponding maintenance methods,and proposes effective preventive measures.
