Abstract
An electronic torque wrench has a tubular core with elongated apertures therein which respectively removably receive user interface assembly and power assembly modules, the modules being exposed through openings in a surrounding grip sheath. A workpiece-engaging head is coupled to a beam member which may received in a tapered opening in a shim member received in an end of the tube. A sensor on the beam member is connected by wires extending to the user interface assembly, which in turn has a display device producing a bar graph display indicating the proximity of a measured torque value to a preset torque level.
