Abstract

A signal is transmitted by a wrench force sensor (42) and a workpiece identification device (36) generates an identification signal, both of these signals being sent to a control device (40). The wrench force signal is compared in the control device with at least one pre-determined or pre-determinable reference signal, and then based on the information from the wrench force and identification signals, the device generates a screw force control signal. An Independent claim is also included for the testing method using this wrench.
