I totally agree , some people do not have a case need to deep down and analysis when do repair service . So with normal task , small and cheap digital multimeter it is enough . But when have a difficult repair, if not enough tools for analysis bug, and repair jobs became blind change electronic componant and finally PCB have a tendency to become collapse .
If deep down understand advantage of Analog Multimeter, specifically as follows current sink and high voltage test -15V 22.5V battery , and high sensitive meter head. Can easy fix problem with high probability, some people have electronic workbench like you ( width area ) can own up to 4 cheap analog meter like Samwa YX-360 ( Fake brand name ), and can extend up to 4 test point with common earth ground. With 4 panel meter can quickly collect state when turn on or turn off machine.
我完全同意,有些人在做维修服务时不需要深入分析。因此,对于正常任务,小型廉价的数字万用表就足够了。但当维修困难时,如果没有足够的工具来分析错误,维修工作就会变成盲目更换电子元件,最终PCB有坍塌的趋势。
如果深入了解模拟万用表的优势,具体如下电流吸收器和高压测试-15V 22.5V电池,以及高灵敏度表头。可以很容易地解决问题,概率很高,有些人有像你这样的电子工作台(宽区),可以拥有多达4个廉价的模拟仪表,如Samwa YX-360(假冒品牌),并且可以扩展到4个具有公共接地的测试点。带有4个面板的仪表可以在打开或关闭机器时快速收集状态。 |
