I'm attempting to read a voltage from Dev2/ai8. The NI-DAQmx has nothing attached to it; it is fresh out of the box.

However, it reading 10.8V:

A second NI DAQ (NI USB-6343) is doing the same thing on analog input 8.
Using the python library, I am also seeing an incorrect yet different reading:
import nidaqmx
with nidaqmx.Task() as task:
task.ai_channels.add_ai_voltage_chan("Dev2/ai8")
print(task.read())
5.458278351573151
Am I doing something wrong?
