摘　　要：目的通过非维修的手段解决心电图机检定中的一些常见问题。方法采用EGC-1C检定仪,参照JJG1041-2008检定规程对心电图机进行检定,分析检定中出现的问题并找出相应的解决方法。结果通过改变心电图机的设置解决了设置问题,通过咨询相关专家或生产厂家以解决设计问题。结论心电图机要严格按照检定规程进行检定,对于检定过程出现问题的仪器不要急于维修,应先对问题进行分析进而找出相应的解决方案。Objective： To solve some common problems in the verification process of digital electrocardiograph through non-maintenance solutions. Methods Verifying digital electrocardiograph with EGC-1C tester according to verification regulation JJG1041-2008, and analyzing problems occurred in the verification process to find corresponding solutions. Results Setting problems are settled by changing the settings of digital electrocardiograph. Design problems can be settled by consulting relevant experts or manufacturers. Conclusion Digital electrocardiograph must be verified according to the verification regulation. The instruments which have some problems discovered by metrological verification don＇t neet to be repaired immediately. We should analyze the problems firstly to find corresponding solutions.
