电子仪器出现故障时,首先必须找出故障所在,进行科学的分析,并通过检查测试和周密的思考作出正确的判断,再根据故障的特点,采取相应的措施予以排除。电子仪器的故障多种多样,产生的原因也不相类同,要对故障现象作出迅速、准确的判断,就要求维修人员具有一定的电路基础和电子线路的理论知识,懂得常用测试仪表的正确 Electronic equipment failure, we must first find out where the fault, the scientific analysis, and through inspection and careful thinking to make the right judgments, and then according to the characteristics of the fault, take appropriate measures to be ruled out. A variety of electronic equipment failure, the causes are not the same, to make the fault phenomenon quickly and accurately to require maintenance personnel have a certain circuit basis and the theoretical knowledge of electronic circuits, to know the correctness of commonly used test instruments
