Features:
1. Safe to use: With reversed connection protection, this item will not burn even when connected reversely , but its screen will display nothing
2. Easy to connect wires: It has only two wires(the red and the black),simply connect the red to positive and black to the negative
3. High accuracy: Its decimal point will automatically move, meaning there is one digit after the decimal point when the voltage is higher than 10V, and 2 digits after the decimal point when the voltage lower than 10V,which allows more accurate display
4. Good-quality material: Its strong plastic case prevents it from easily damaged by outer force.Ã¯â€ºmore, high-quality LED is adapted in this item, which is bright even in dim light

Wiring connection:
Red wire: connect to input positive pole
Black wire: connect to input negative pole

Potentiometer usage:
You should adjust the potentiometer when your input voltage is about 20V. Please use a screwdriver to adjust the potentiometer to meet your requirements.

Applications:
You can use this meter to monitor voltage or battery of cars, vehicles, sailboat, RV, truck, race car, automotive, etc.
