Abstract
An electrical test device for use by an electrician in testing circuits. The device includes a voltage sensor, display, voltage transducer and steady current source. The voltage sensor measures the voltage between two conductors and provides a signal to the display, which responsively displays the voltage. The steady current source is in series with the voltage transducer, so that the voltage sensor may respond to a broad range of voltages while only a limited amount of current flows through the voltage transducer. Consequently, lower cost components may be used in the voltage transducer.
