analog voltage measurement using NI USB-6210

[GHernandez]

Hello everyone,
I am trying to take a voltage measurement using DAQMX.  I tested this sensor and I am sure that it works.  I keep reading the same voltage when i am touching the sensor, which should not happen. On the other hand, when i use MAX configuration i get the proper reading except it gives me an array of measurements, when i have specified a single point read. Here are the images..

You might want to wire up your indicator to the DAQmx Read output.

doh, i forgot to wire it before I took the screenshot. I wired it and i am still getting the same voltage reading. 😞

The only real difference I see is with the different ranges you have. Other than that, it looks like you should get the same results. Maybe someone else will see something wrong.

AH, the problem was i didn't configure the type of measurement it was: differential or reference single ended.
It seems to be working now. thanks!!
