0.36inch Mini Digital Voltmeter DC 3V to 32V Digital Voltmeter 0-100V Voltage Panel Meter Red

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. Normally, no external working power supply is needed, and the measuring voltage can be directly operated. The measuring voltage range is 3-32V /0-100V. 3, wide voltage operation, the red minimum measurement voltage is 23, the maximum safe preure can reach 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. Measuring range： Two-wire DC3~32V / Three-wire DC0-100V Power supply range No separate power supply. Measured voltage 50KΩ Working current：
