Hi, I have a 6485 which is not working. There is no display of value. Error reading Read command in GPIB (timeout) I read all topics here, used preamp schematic v2 to check input preamp is working, I have proportional voltage on analog output I look to check ADC, it's OKI component (2000-802A04) In my board, it's a bit different, it's a new version 2X00AD component. Does anyone have documentation on this component or old version ? Thanks in advance |
