Abstract: A device for measuring impact pulses wherein an acceleration pickup converts the mechanical vibrations of an object into electric signals passing through an amplifier unit to a meter for measuring the parameters of the impact pulse. This meter comprises two null-indicators, one of which is connected electrically and directly with the amplifier unit while the other one is connected across a voltage divider connected to a source of a reference voltage, two pulse shapers connected to the null-indicators, two AND-NOT logical elements connected with the pulse shapers and a H.F. pulse generator. The meter comprises one more AND-NOT logical element connected with one of said AND-NOT logical elements and with the most significant and least significant decades, the least significant decade being connected with the other one of said AND-NOT logical elements.
