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
