0.36 Inc 2 Wire 0.36' DC 4.5 30v 3 Display Voltmeter Mini LED Digital Voltage Meter Instrument Red/Blue/Green digital voltmeter

1. The wiring of this voltmeter is simple. The two wires are used regularly. The red is connected to the positive, the black is connected to the negative, and the reverse connection is protected.

2, the conventional need no external working power supply, can work directly with the measured voltage, measuring the voltage range of the second line 4.5-30V.

3, wide voltage operation, red minimum measurement voltage 4.5V, maximum safe pressure up to 40V, more than 40V may be damaged.

4. When measuring voltage below 10V, two digits are displayed after the decimal point; when measuring voltage above 10V, one digit is displayed after the decimal point.

Note:Low-start operating voltage, minimum 4.5V for red, 4.7V for green, and 5.0V for blue.
