ok so from my understanding if i am using the RSE configuration I need to wire one reference of the pot to the + terminal of my power supply, the other reference to the - terminal of the power supply and the wiper to the CH +0 pin on the DAQ. Then I also need to wire the - terminal of the power supply to the AI ground pin on the DAQ.
Have you tried measuring the voltage difference between the wiper and ground using a DMM? The best thing to do is to verify that the signal is correct before we begin reading it using a DAQ device.
Yeah when i measure the voltage with a DMM I get the correct results. The Dmm reads 5v when the actuator is not extended, then it moves to 0 volts as I extend the actutor.
