Feature: 1. The wiring of this voltmeter is simple. The conventional two wires are used, the red is connected to the positive, the black is connected to the negative, and the reverse connection is protected.
2. Conventionally, no external working power supply is required, and the measuring voltage can be directly operated. The measuring voltage range is two-wire 2.50-30V.
3. Wide voltage operation, red 2.50V low and safe pressure up to 40V, more than 40V may be damaged.
4. When measuring voltages below 10V, two digits are displayed after the decimal point; when measuring voltages above 10V, one digit is displayed after the decimal point.
