Abstract
A method for improving the accuracy and repeatability of torque applied by discrete energy tools subjected to a wide variety of joint conditions. The method includes relating air pressure to output torque and compensating for temperature and aging variations. Additionally, the method may include a process for detecting previously tightened fasteners.
