Abstract

A method is provided for calibrating an electronic torque wrench ( 100 ) engaged with a torque tester ( 302 ), according to a specified calibration procedure that includes increasing an applied torque to a target torque value, and a threshold time rate of change of the applied torque. The method includes detecting the applied torque produced from a rotational force applied by an operator to the electronic torque wrench ( 100 ). The method includes, as the applied torque is detected, determining a torque value of the applied torque, and a time rate of change of the applied torque. The torque value and the time rate of change are compared to respectively the target torque value and the threshold time rate of change. And a notification is output to guide the operator in the rotational force applied by the operator, and thereby the applied torque produced from the rotational force.
