The scale is tied with the Global Virtual Channel you created in MAX. You should be able to bypass the scale by reading the physical channel. See the attached diagram.
When I was in MAX, I created an NI-DAQmx Task, not a global virtual channel. To this task I added all of my signals and applied the appropriate scaling there. If I have done it this way is there a way to obtain the prescaled voltage?
Reading the physical channel should bypass the task scaling as well. The diagram I posted is really just creating a task programatically and bypassing MAX all together.
