Description Welcome to our store:beestudio 2016 Tips: If you need Large quantity, please contact us, we can wholesales. Specification: Feature description: 1. The wiring of this voltmeter is simple. Two wires are normally used. Red is connected positive, and black is connected negative. There is reverse polarity protection within it and the opposite is not burned. 2, conventional without external power supply, can work directly with measurement voltage, measuring the voltage range of 2-wire 2.4-30V. 3, wide voltage operation, red minimum measurement voltage 2.4V, maximum safety pressure up to 40V, more than 40V may be damaged. 4. When measuring the voltage below 10V, two digits are displayed after the decimal point; when measuring the voltage above 10V, one digit is displayed after the decimal point.
