Product description
With this digital voltmeter dc 0-100v 3-wire c, you can instantly view voltage data and digitally measure the voltage of your electronic circuits or devices operating between 4.5-28v (max 30v). furthermore, as long as the source connected to the product's anode and cathode terminals is a maximum of 30v, you can measure the voltage of another device by connecting its cathode to the digital voltmeter's cathode and its anode to the digital voltmeter's white wire, allowing you to see values within the 0-100v range.
