I am getting a DC offset on my input signals using NI 4472 with ICP accelerometers

I am getting a DC offset on my input signals from my ICP accelerometers. I tried to remove this by selecting AC coupling on the NI-MAX channel setup.

When you set up a accelerometer virtual channel in MAX with the built-in excitation for the 4472 you will also need to set the DSA Excitation in LabVIEW. The MAX setting for the built-in excitation does not get imported. All the other settings should though, including the coupling. If you are using the built-in excitation you should be using AC coupling.

Hope this helps.
