Hello,
I feel like this is a stupd question, but I cannot figure it out for the life of me.
I have a pretty straight forward OMEGA pressure transducer configured for mV output (http://www.omega.com/Pressure/pdf/px309-100mv.pdf).
It has 4 wires, white (+ output), green (- output), red (+ supply) and black (- supply). I have a simple 12V (DC) power supply (wall plug) to supply the power (red to positive, black to negative), and I have the white and green wires connected to the + and - analog input of the DAQ (Ai1, 17/18). However, with NI MAX, I cannot see any signal being generated. I have tried different PXs, different inputs, seemingly everything, but I can't figure it out. The power supply shouldn't be the problem I don't think, it defintely has enough current and voltage.
Anyone have any idea? Thank you in advance.
