AB Series Strain Calibrator

Description

The Model AB 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 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 AB calibrator to
provide the stability, repeatability and accuracy required in a laboratory strain gages instrument.
