Abstract
The monitor system consists of a voltage controlled oscillator for produc an acoustic wave whose frequency is proportional to the voltage being measured. An acoustic waveguide is used for transmitting the wave to an electrically isolated acoustic to electrical transducer. The output of the transducer is amplified and then displayed on an appropriate readout calibrated in volts.
