I have the NI-9222 module connected to a cDAQ-9174 chasis. Connected to the module is a piezoelectric sensor, which produces a voltage signal. Oscilloscopes and multimeters read the output voltage of the sensor for our specific application to be roughly 150mV. When using the NI hardware, LabVIEW (and NI Max test panels) are reading values of roughly 5V. The sensor cannot realistically output such a high voltage, so I am led to believe that the hardware is amplifying the signal. I have looked though the settings, but have not been able to find any way to remove this amplification. How can I go about doing this?
