The Model AE calibrator is a Wheatstone bridge and generates a true change of resistance in one arms of the bridge.

It simulates the actual behavior of a strain gage(gauges) in negative strain calibrator based on the Wheatstone bridge principle requires stable components. Multiple ultra-stable and hi-stable precision resistors are used in the Model AE calibrator to provide the stability, repeatability and accuracy required in a laboratory strain gages(gauges) instrument.
