Yellow 0.28 Mini Voltmeter
Yellow 0.28 Mini Voltmeter 0.2-100V Two Wire DC yellow Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink. The red wire is to connect to the positive pole, the black wire is to connect to the negative pole. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection.
