    Need Help with finding the waveform of pressure sennsor MPS-3117

    Hi, I'm new here and there are some questions I want to ask regarding the pressure sensor. I was supposed to find the waveform of this pressure sensor from a PCB board using a oscilloscope and power supply. However, I am having problems as this sensor that I am dealing with has an '+input','-input' and '+output', '-Output' as shown in this attachment. MPS-3110series.pdf. I have tried google and other websites but to no avail. I would really appreciate any advice given. Thank you in advance.

    The circuit is a Wheatstone Bridge. Your readings will be analog directly from the circuit.
