Abstract
The invention relates to a percussion instrument to obtain error-free measurements during diagnosis and test tasks, said instrument generating defined and constant mechanical shock pulses, either singly or at intervals, irrespective of the distance to the test object by means of a magnetic, movable tappet having a sensor integrated in the tappet to measure the decelerating procedure occurring with every shock movement, whereby an automatic calibration of the instrument is performed by means of sensor signals obtained by two internal stoppers integrated in the instrument and the device function being monitored during the measurement operation.
