Key Features
3-wire digital voltmeter detection voltage: DC 0~100V, working voltage: 4~30V (with reverse connection protection function)., Note: The three-wire voltage range of 0-100V, can also be used for the second line but the voltage should be within 30V., It can work with 5V, 9V, 12V and 24V. Adjustable voltage resistance, Rotate clockwise to lower the voltage., There are 4 colors of light to show the measurement results: Red, Green, Blue, Yellow., Size: 30*10*8mm, weight: 5g.
