Abstract
A torque wrench is disclosed having torque range indicators. The torque wrench includes a handle, a torquing tool, a mounting bar and a programmable interface module. At least one torque sensor is communicatively coupled to the interface module. The interface module includes an input device able to receive at least one predetermined torque value, a torque value indicator, a torque range indicator, and a controller. The torque value indicator, the torque sensor, and the torque range indicator are communicatively coupled to the controller, and the controller is programmed to activate the torque range indicator based on a torque range calculated by comparing a torque value received from the torque sensor to the at least one predetermined torque value.
