摘要: A hand-held instrument for testing wire circuits. tricolor light emitting diode is utilized to indicate the existence of a signal in data bus. The displays different signals presence either alternating or direct current, polarity and continuity circuit. Voltage circuit indicated by variation glow intensity an incandescent lamp. adapted servicing troubleshooting circuitry on board commercial aircraft, including both bus circuits other current
