Features:

< Reverse polarity protection: The meter won't burn out if reverse polarity is applied, and the screen will display nothing.

< Convenient to use: It can work directly in 5v, 9v, 12v, 24v .

<  Application: Measuring range: DC 0-100V, suitable for 2-wire and 3-wire operation.

<  3 wires: Designed with 3 wires, easy access to the car/battery/motorcycle car circuit.

<  Multifunction: It is used to monitor the battery voltage, knowing the battery voltage status in time, and can also be used as voltage meter for other devices.

Warm tips:

<  When in 2-wire operation, please note that the  MAX. input voltage should not exceed 30V.

< When in three-wire  operation, voltage range is 0-100V, which can also be used for two-wire, but the voltage range should be within 40V
