ABSTRACT:
Mulit-mode voltage and continuity testing apparatus is disclosed for effecting a single pole phase mode of testing, and comprises first and second testing terminals, a loudspeaker, a battery energized oscillator having a control input, a control transistor, and first and second resistances. Circuitry is provided for directly connecting the battery through the emitter and collector of the control transistor to the control input of the oscillator circuit, and the first testing terminal to the base of said control transistor, whereby the testing apparatus effects a single pole phase mode in which a voltage source to be tested is connected to said first testing terminal.
