Abstract
An electronic torque wrench including a wrench body, a wrench head configured to engage a workpiece, a first sensor producing a first output signal, that is proportional to an amount of torque being applied to the workpiece, a grip handle, a second sensor producing a second output signal that is proportional to an amount of rotation being applied to the workpiece, a user interface including an input device for inputting a preset torque value, and a processor for converting the first output signal into a current torque value, comparing the current torque value to the preset torque value, and converting the second output signal into a first angle value through which the workpiece has been rotated after the current torque value exceeds the preset torque value.
