Through connecting this product to the outputs of your electronic circuits or devices which operate between DC 4.5-28V(max 30V), you can see voltage datas instantly and measure voltage digitally. Also, if the connected source between product's anode and cathode legs are max 30V, by connecting another device's that you want to measure its voltage, cathode to digital voltmeter's cathode and its anode to digital voltmeter's white cable, you can see values between 0-100V.
