Yhteenveto

1. The voltmeter has simple wiring. It usually uses two wires, red for positive and black for negative. It has reverse connection protection, so it won't burn if connected in reverse.
2. It doesn't need an external power supply. It can work directly with the measuring voltage. The measuring voltage range is 2.4V-32V for two lines.
3. It works with a wide voltage. The minimum measuring voltage of red is 2.4V, and the maximum safe pressure can reach 40V. It may be damaged if it exceeds 40V.
4. When measuring voltage below 10V, two decimal places are displayed; when measuring voltage above 10V, one decimal place is displayed.
