Abstract: A circuit is connected to an ultrasonic transducer being fed by a constant current or constant voltage power supply. By rectifying, integrating, and amplifying the transducer coil voltage an output signal that is a function of the transducer and load impedance is provided that can be displayed so as to determine the operating condition of the ultrasonic apparatus.
