Dear Experts, I have a project were I need some source of current 0-20 mA. , and for this I use 3 module AO . Please someone can help me , I have tried different configurations, the program seems to works in good condition, in the online mode all the parameters look OK. , but no current to PQW . More than 3 weeks spend a lot of time and dont know what more can I do . I expected to have 0-20 mA but measure with multimetter (200 ohm In series with the measuring device ) have only 0.20 mA per one chanel , the rest fizic do not work . First , when I made the program with one module worked, but when I put the other two AO modules did not work anymore and I do not know what to do . please see pdf attachment with some screen save . thanks for any suggestion where I must to check .

I checked the software and cable connections. There has to be revolved some adjustments to the software and some wiring about M_ANA. When I had this problem , I spoke to a friend and told me to check the multi meters for the first time, and I find now that someone burned the fuses.... Anyway this guy usually comes to give me a hand after I break my head looking for solutions. In fact, the defect consisted of the fuses fired from the two measuring devices, as seen in the pictures in pdf, and I realized that after I had empirically checked the AO outputs with a Led. The problem is solved and I keep open this topic, maybe will be useful for some guys to learn from this mistake . Thanks. AttachmentWP_20170625_13_40_19_Pro.pdf (195 Downloads) |
