Patent ID: 8714057

Claim:
An electronic torque wrench for engaging a workpiece, comprising; a wrench body; a wrench head disposed on the wrench body, the wrench head being configured to engage the workpiece; a ratchet assembly disposed between the wrench body and the wrench head so that torque can be applied to the workpiece using multiple rotational cycles of the electronic torque wrench without having to disengage the workpiece; a first sensor operatively coupled to the wrench head and producing a first output signal, the first output signal being proportional to an amount of torque being applied to the workpiece by the torque wrench; a second sensor operatively coupled to the wrench body and producing a second output signal, the second output signal being proportional to an amount of rotation being applied to the workpiece by the torque wrench; a user interface carried by the wrench body, the user interface including a digital display with a first readout and an input device for inputting a preset torque value; and a processor that receives the first output signal and the second output signal and is programmed to convert the first output signal into a value of a current torque being applied to the workpiece, compare the value of the current torque to both the preset torque value and a value of a peak applied torque to which the workpiece has been subjected, and convert the second output signal into a first angle value through which the workpiece has been rotated after the value of the current torque exceeds both the preset torque value and the value of the previous peak applied torque.
