Features:
Protection: Reverse connection protection, the item won’t burn out if reverse polarity is applied, more safe to use.
Convenient to use: This digital voltmeter can work directly in 5v, 9v, 12v, 24v.
Mini size: Compact and lightweight, convenient to take to everywhere.
Wide application: Can be used to measure the voltage of motorcycles, automobiles and more.
The decimal point shifts automatically:
1. When measured voltage is below 10V, the voltmeter displays two decimal digits.
2. When measured voltage is higher than 10V, the voltmeter displays one decimal digit.

Warm tips:
Please note that the input voltage must not exceed 40V, avoiding burning.
