DC 0-30V LED Display Digital Voltmeter Board Two-Wire Mini Digital Voltmeter Voltage Tester Meter Panel

Brand New and High Quality DC 0-30V 2 Wire LED Display Digital Voltage Voltmeter Panel Measuring range: DC 0.1V-30V Input range: DC 2.7V-32V Max Input: DC 32V. The device can be damaged if input is over 32V Display: Three 0.36 "digital tube Measurement accuracy: 0.1% Refresh rate: about 300mS / times Input impedance: About 100K Screw holes measures :28mm Package Include: 1 x Digital volt meter Note: Simple wiring, conventional with two lines, the redline is connected to the positive pole, the black line is connected to the negative pole. With the protection of opposite connection, secure to use. Conventional no external power supply needed, you can use the measurement voltage directly to work, measuring voltage range from 4.5-30V. Wide voltage work, the red display minimum 4.5V, maximum safe pressure up to 30V, more than 30V may cause damage. When measuring the voltage below 10V, down to the second decimal point; in the measurement of more than 10V voltage, down to the first decimal point.
