ABSTRACT:
A passive voltmeter that measures pulses of high voltage by periodically charging a condensor through a spark gap. The frequency at which the spark gap breaks down is a function of the voltage being measured and is detected and displayed in volts. Radioactive material within the chamber is used to insure a constant breakdown voltage by supplying the necessary free electrons. This insures constant breakdown time for the arc with minimum jitter.
