Hello,
I have an NI PXIe-6361 device and am trying to wire up a simple circuit with a switch so that when the switch closes, the DAQ reads a voltage and when the switch is open the DAQ reads no voltage.
Ideally I would like to provide the voltage from the 6361 itself if that is possible. My question is, how would i wire up such a circuit to the ports on the NI 6361. I have been told that I will need to connect a ground to prevent the readings from floating, is this just a case of connected to the AI GND terminal? This is what I have in mind but my electronics knowledge is very limited!....
Many thanks for your help.
Sam
