A load monitor for a cyclic machine has a peak load signal detector the output of which is displayed indefinitely on an analog meter. On each cycle of the machine, the analog load signal is converted to a digital signal and the digital signal is converted to an analog signal connected with the analog meter. Overload and underload reference signals are established during a selected single cycle of machine operation.
