日本福田公司生产的VA--3G心向量图机由主机、X-Y记录器与照相记录装置三部分组成。主机设有CRT监视器,可实时显示向量心动及标量心动图。此类监视器无扫描基线、亮度弱或聚焦不良等故障时有发生。下面结合一例无扫描故障的检修,谈谈该监视器高压发生器的组成特点,故障检修及检修过程中应注意的几个问题。 Fukuda Japan company produced VA - 3G heart vector map by the host, X-Y recorders and camera recording device consists of three parts. Host with a CRT monitor, real-time display of vector cardiac and scalar cardiogram. Such monitors without scan baseline, weak or poor focus poor failure occurs. The following combination of an example without scan troubleshooting, talk about the composition of the monitor high-voltage generator features, troubleshooting and repair process should pay attention to several issues.
