1. An electronic system for generating signals representative of the performance of a pneumatic tool during one or more work cycles wherein said pneumatic tool includes a working cylinder and gaseous actuating fluid contained therein, said electronic system comprising:

  • means to generate a signal in real time representative of the actuating gaseous fluid pressure in the work cylinder of said pneumatic tool;

    first means to operate at times on said real time pressure signal only over a selected time portion of each of said work cycles for generating a signal representative of the energy developed in said pneumatic tool during said time portions; and

    second means to operate at times on said real time pressure signal only over a selected time portion of each of said work cycles for generating a signal representative of the friction developed in said pneumatic tool during said time portions.
