Issue Details

When I try to read from my DAQ Device in DAQExpress I see the voltage sweep from -10 V to 10 V. This is not the data i expect. What is wrong?

Solution

Check to make sure you are not pulling data from a simulated channel. In DAQExpress, you can load a Simulated Input Voltage Task that will simulate a sine wave. Make sure your channel is not configured to read from a SimDev channel.
