像楼主这样来检查线路板，一般人很难做到，要具备相当熟悉的相关电路知识和动手能力，连仪器厂家都是整个板子换。

这个帖子牛啊！崇拜ing!

楼主是电子专家啊，对电路很熟悉。
是不是电子工程专业毕业的啊？还是分析化学专业毕业的呢？
俺很好奇。

学的是农化，干的活是电子，碰巧二合一都用上了

给大家看看传说中的光电倍增管

这个光电倍增管是热电气质中用的？

收藏啦，这个相当有用

光电倍增管不象是用在质谱仪上的吧？看线圈好象是离子阱的仪器，是不是传输数字信号的光耦坏了？楼主真的很厉害！

光电倍增管是美谷分子的酶标仪上用的 可惜那台机器给一个混蛋搞报废了

同样遇到RF自检错误，自检信息如下。大侠能看看RF哪个版块出问题了不？
