NOTE: IEPE is an acronym for Integrated Electronics Piezoelectric types of low impedance voltage mode sensors

with built-in amplifiers operating from constant current sources over two wires. IEPE instruments are compatible

with most other manufacturers' comparable systems.

Page 5 Often our service engineers may point out something which may have been overlooked and which may save the expense and time of returning the 3089A to the factory. If the instrument must be returned, the service department will issue you a Returned Materials Authorization (RMA) number to aid in tracking the repair through the system.
