1. A method for evaluating a condition of a torque wrench comprising:
connecting the torque wrench to an adapter;
detecting a click point, where a click mechanism of the torque wrench is decoupled from a first position into a second position, and measuring a click torque value at the click point;
detecting a peak point and measuring a peak torque value at the peak point;
detecting a release point, where the click mechanism is moving back from the second position into the first position, and measuring a release torque value at the release point; and
determining that an evaluation was performed correctly if the click point, the peak point, and the release point were detected.
