ABSTRACT:
A method and apparatus for measuring the torque generated by a slip-type fastening device (e.g. an air driven wrench) that generates multiple torque spikes. The method measures the torque by monitoring the torque output of the device as the torque increases. When the torque reaches a peak and drops, the measured torque value is displayed. No further torque outputs of the device are then displayed. The apparatus includes a first section which receives the torque output of the device and converts it into a torque signal. A second section displays the highest torque value received. The improvement is a third section which connects and disconnects the first and second sections based on the torque output of the device. When the torque output first increases, the first two sections are connected so that torque signals are passed from one to another. After a drop in the torque output, the two sections are disconnected and the highest torque value is displayed.
