DROK 090077 Small Little DC Digital Voltmeter 2-Wire
Parameters: Dimensions: 48mm x 29mm x 22mm Cutting size : 46mm x 27mm Measure voltage: DC 3-30V (two wires Access) Input Polarity: DC voltage Measurement precision:0.01V(3-10V); 0.1V (10-30V) Display: Three 0.56" digital LED Tube Display Color: Green Refresh rate: about 500mS / times Operating temperature: -10°c to 65°c 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.；more, 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.
