CALIBRATION TOOL FOR TORQUE WRENCH

摘要

A calibration tool for a torque wrench includes a measuring head and a deflecting lever. On the deflecting lever are a signal processing unit, a communication unit and a calibration unit. The measuring head has a transducer configured to have a head portion of the torque wrench coupled thereto. The transducer generates measured signals during the calibration. The deflecting lever is provided for exerting a torque on the head portion of the torque wrench. The signal processing unit is electrically coupled to the transducer for processing the measured signals of the transducer. The communication unit associates with a data storage of the torque wrench for a data exchange therebetween. And the communication unit reads out the data storage of the torque wrench for obtaining a preset torque of the torque wrench for a release. The calibration unit calibrates the torque wrench by comparison of the torque exerted in the moment of the release to the preset torque at the torque wrench.
