This voltmeter has the smallest volume in the world, and the measuring range dc dc0-100v, 2-wire and 3-wire products are universal. It breaks the conventional voltmeter. Equipped with three connections, it is convenient to access the line in the car/battery car/motorcycle. It has the function of reverse connection protection. It can be used to monitor the voltage of the battery, master the voltage state of the battery in time, and can also be used for voltage measurement of other products. Note that the maximum input voltage of line 2 should not exceed 30V, otherwise there is a risk of burnout.
Note: the three-wire voltage range is 0-100v, which can also be used as a second-line, but the voltage should be within 40V
