Product parametersMeasuring range DC 0-100V, 2-wire and 3-wire products are universal, breaking the conventional voltmeter, and can directly work in 5V, 9V, 12V, 24V and other circuits,No voltage stabilization is required. Equipped with three wires, it is convenient to connect to the lines in cars / battery cars / motorcycles. It has the reverse connection protection function, and the wires will not burn when connected reversely.It is used to monitor the battery voltage and grasp the battery voltage status in time. It can also be used for voltage measurement of other products.Note: 1The input voltage of line 2 shall not exceed 30V, otherwise it may be burnt.Note 2:The voltage range of the three wire is 0-100V, and it can also be used as the second wire, but the powerThe voltage should be within 30V.

Product features:Break the routine, no need to stabilize the voltage2-wire and 3-wire products are universal, breaking the conventional voltmeter, and can work directly in 5V, 9V, 12V, 24V and other circuits without voltage stabilizationReverse connection protection is not afraid of burningIt has reverse connection protection function, and is not afraid of burning the equipment even if the wire is connected reverselyGeneral purpose of line 2 / Line 3 productsEquipped with three wires, it is convenient to connect to the lines in cars / battery cars / motorcycles. The 3-wire voltmeter can be changed to 2-wire, which is convenient and practical
