Hello,
I have the following circuit hooked up to my DAQ via the DIP relay. Essentially in this circuit, when the wires labled Lick Tube and Chamber Floor are each held in different hands so that I'm completing the circuit through my body, there should be a voltage drop that shows up on the Measurement and Automation Explorer. However, when I do this, I'm getting no signal and instead a lot of 60 Hz noise. I have tried this circuit on a USB-6008 and got perfect results. Does anyone have experience with this board? Do I need to ground the board itself somehow? Any input is appreciated.
