AG 34401a报错误612 618
我的AG 34401A 报了一个612 和618的错误。刚开机的时候自检就会报这个错。担等热机了10分钟左右再开机自检就PASS了。搞不太懂,不知道从哪里下手,请高手指点,网上查的手册说:618:DC high voltage attenuator failed This test configures to the 1000V dc range. The 500 nA ohms current source is connected to produce a nominal 5 V signal. A 20 ms ADC measurement is performed and the result is checked against a limit of 5 V ± 1 V.
612 Ohms 500 nA source failed This test configures to the 10 V dc range with the internal 10 M 100:1 divider U102A connected across the input.The 500 nA ohms current source is connected to produce a nominal 5 V signal. A 20 ms ADC measurement is performed and the result is checked against a limit of 5 V ± 1 V.
望高手指点指点
顶起,有朋友知道么?? 是每次都这样的情况:冷机时候自检FAIL,热机时候自检PASS? 换电容吧,电解电容的概率最大 海涛 发表于 2015-11-13 23:42
换电容吧,电解电容的概率最大
请问是哪个电解电容的问题,????
先查几路供电,再查基准输出的几路电压,另外查下K101是否有阻值! 修复了没有 中国之声 发表于 2016-1-5 18:14
修复了没有
朋友,先谢谢你,但还没有修复 ,能否指教。
检查一AD637第12,13脚电压是否在正负15V
