All, I am using an older USB 6218 to acquire voltages from a few sensors. I tried to test the the LabVIEW program I created to acquire these voltages by using a DC power source, the DAQ Assistant will not read the correct voltages that I am inputting. I made sure that the DAQ assistant was set to differential input and that it was wired correctly, and also tried wiring it up as RSE and switching the DAQ assistant to RSE, but this did not help. To make sure that the USB 6218 was not faulty, I used the NI Max software and also a MatLab program I found online. Both of those programs were able to read the correct voltages. What could be going wrong here? In my program, I use the DAQ Assistant to acquire the signals, and then use the split signals function to get my individual signals for data processing. Thanks in advance!
