You can program the FieldDAQ device to supply 4 mA of IEPE excitation current to an AI channel for applications using an IEPE accelerometer or microphone. You can independently configure IEPE signal conditioning on a per-channel basis on the FieldDAQ device.
When you enable IEPE signal conditioning, the sensor generates a DC voltage offset that is dependent on its design; enable AC coupling, described in Input Coupling, to remove this unwanted DC offset.
