Abstract : An electronic meter circuitry for use in detecting an electrical signal voltage in an ordnance firing circuit for providing an unidirectional signal to an indicator which shows the presence of the signal voltage. The circuitry utilizes a first limiter to reduce the amplitude of the detected signal to a predetermined level, a bridge rectifier to provide a unidirectional signal and a second limiter to prevent overloading the indicator. A self contained test circuit utilizing a current source and two current limiting resistors is supplied so proper operation of the meter circuitry prior to use may be readily ascertained. (Author)
