    I've never used a 6014, but with the ni e-series boards 
(multifunction DAQ) this can happen if you have configured the analog 
input in differential mode and have not connected properly your signal. 
I would recomend you to connect the reference of your signal to the 
AIGND pin of the board and try again.
