    摘要: The invention provides an electronic wrench which includes means for measuring the instantaneous applied torque and means for measuring the instantaneous angle of rotation during tightening. The physical parameters of the screw connection for tightening and a setpoint value for the tightening are initially entered into the wrench via a keypad. During the tightening operation, the processor means calculate the instantaneous traction force on the screw fastener as a function of the measured instantaneous values of torque and angle and as a function of the recorded characteristics of the screw fastener.
