Abstract
A method and system for unlocking a calibratable electronic torque tool and a torque testing device and the calibratable electronic torque tool. To unlock the calibratable electronic torque tool, a tool head of the calibratable electronic torque tool is coupled to the torque testing device and a direct data link is established. The calibratable electronic torque tool and the torque testing device separately determine torque test values, which are transferred to a data processing device of the torque testing device and compared with each. If the difference between the torque test values is within a specified or specifiable tolerance range, an unlocking signal is transferred to the calibratable electronic torque tool via the data link and the calibratable electronic torque tool is unlocked by overriding a lock via the transferred unlocking signal.
