PURPOSE: An automobile digital meter is provided to easily identify whether the wiring of the electrical circuit is short or not by the buzzer sound generated from the buzzer although the power of the digital meter is turned off. CONSTITUTION: An automobile digital meter includes a battery(100), a power controller(200), a meter block(300), an illumination block(500), a display block(600), a voltage value display block(700) and a buzzer generator(800). The battery(100) supplies the power to the digital meter. The power controller(200) outputs the measure voltage to the voltage value display block(700). The meter block(300) is composed of an inspection pin for inspecting the short of the wiring. The illumination block(500) is composed of a lamp for emitting a light. The display block(600) is provided with a power display light emitting device and a display light emitting device. The voltage value display block(700) displays the measured voltage value on the display screen. And, the buzzer generator(800) generates a buzzer sound in response to the status of the short of the wiring.
