Abstract
A torque wrench including a handle attached to a drive member and a transducer that senses the torque transferred from the handle to the drive member and outputs a first signal corresponding to the transferred torque. An analog mechanical input device disposed on the handle that simultaneously defines a set point and indicates the set point. A comparator receives the first signal from the transducer, receives the set point, compares the first signal from the transducer to the set point, and outputs a second signal. The mechanical input device does not display a real time measurement of the torque transferred to the work piece prior to reaching the set point.
