ABSTRACT:
The present invention relates to a torque wrench (1, 2) having an electronic measuring device which detects a prevailing torque by means of strain gauges, having a memory for the storing of measured values and an indicating device which indicates the minimum and maximum values reached by means of light-emitting diodes (5, 6, 7) of different color. In order to be able to use the torque wrench advantageously, in particular in routine work where the precise maintaining of a torque is of importance, the invention proposes that a measured value be stored by actuating an actuating button (8) which also serves to activate the torque wrench (1, 2).
