介绍了俄罗斯工业部门生产的诊断仪器和诊断装置，这些仪器和装置可以推荐给按俄罗斯交通部规程规定对电力机车进行日常修理和技术维护的机务段维修人员。这些装置是在全俄铁路运输科学研究院电气化分部科学工程中心的专家们参与下研制和挑选的。这些专家利用综合检查和诊断系统制订了机车修理的工艺过程。在这种情况下，选择诊断系统和装置的主要标准是测量结果的可信性及计量学保证。建立在高精度仪器之上的主要技术诊断任务为：在运用过程中以规定的可信性检查整个设备及其组件的工作性能；在技术维修时确定某一工序的实际要求。在日常修理时，通过能保证判定缺陷处所、类型和原因的深入探索寻找缺陷，检查修理质量；在预测残余寿命时，收集、处理和分析有关部件和机组的技术状态的信息，作出能否继续使用、所需修理工作量的决定。如果质量标志不能为技术状态结论提供可信的评定，则修理人员可按自己的判断有选择地使用测量装置和仪器。日常修理时，必须按照选定的设备类别的工艺卡片采用诊断装置。
The diagnostic instruments and diagnostic devices produced by the Russian industrial sector are introduced. These instruments and devices can be recommended to locomotive maintenance personnel who routinely repair and maintain electrical locomotives in accordance with the regulations of the Russian Ministry of Communications. These devices were developed and selected by experts from the Electrification Division Science and Engineering Center of All-Russia Institute of Railway Transportation. These experts have used integrated inspection and diagnostic systems to develop a locomotive repair process. In this case, the main criteria for selecting diagnostic systems and devices are the credibility of the measurement results and the metrological guarantee. The main technical diagnosis tasks that are based on high-precision instruments are: To check the workability of the entire equipment and its components with the specified credibility during the operation; Determine the actual requirements of a process during the technical maintenance. In routine repairs, defects can be identified by in-depth exploration to ensure the location, type and causes of defects, and the quality of repairs can be checked. Information about the technical status of the relevant components and units can be collected, processed and analyzed when the residual life is predicted. Use, the amount of repair work required. If the quality mark does not provide a credible assessment of the state of the art conclusion, then the mechanic can use the measuring device and instrument selectively at his or her discretion. For routine repairs, the diagnostic device must be used according to the technology card of the selected device category.
