How do I use the DAQ Assistant subVI to display voltage readings from a potentiometer

And why don't you have the AI gnd connected to anything?

is that the ground on the DAQ terminal? should it be connected to an external ground?

Read about wiring.

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.

I tried the following RSE terminal configuration, however I am still getting the same results as before.

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.
