A torque calibrator allowing the accurate calibration of impact type wrenches. The calibrator measures the displacement of a heavy fixed beam in its natural oscillation mode. The beam has a long period of natural oscillation and an elastically soft segment preventing generation of rebound signals sometimes seen in stiff systems.
