This voltmeter is the smallest in the world, with a range of DC0-100V DC, common for 2-wire and 3-wire products. It breaks the conventional voltmeter. It is the latest design and can directly work in 5V, 9V, 12V, 24V and other circuits without voltage regulation. Equipped with three wires, it is convenient to connect to the car/battery car/motorcycle wiring, with reverse connection protection function, and the wire connection will not burn. It is used to monitor the battery voltage, grasp the battery voltage status in time, and can also be used for other product voltage measurement purposes. Note that the maximum input voltage used for 2-wire cannot exceed 30V, otherwise there is a danger of burning.
Note: The voltage range of three-wire use is 0-100V, and it can also be used as two-wire but the voltage should be within 40V
