0.28-inch Small Digital Display DC Voltage Meter with 2-wires DC2.5-40V Adjustable Reverse Connection ProtectionItem NO.: 2-wire 0.28inch

0.28-inch 2-wire Voltmeter Head

Two wires, easy and simple to connect, convenient for connecting to the wiring inside cars/electric scooters/motorcycles, with reverse connection protection function, the wire will not be burned when connected in reverse, and has fine adjustment function;

Function Introduction:

1. Range: 2.5-40V (red) 2.6-40V (yellow) 2.6-40V (green) 3.2-40V (blue)

2. Equipped with two wires, the wiring is convenient and simple, making it easy to connect to the wiring inside cars/electric scooters/motorcycles;

3. It has reverse connection protection function, and the wire connection will not be burned when reversed, with fine adjustment function;

4. Please note that the input voltage should not exceed 40V, otherwise there is a risk of burning.

When the voltage is below 3.0V, the display brightness will dim, but it does not affect the correct measurement

When measuring voltages below 10V, display two decimal places after the decimal point; When measuring voltages above 10V, display one decimal place after the decimal point. It can meet both the measurement accuracy needs of battery users and the need to measure higher voltages.

Measurement accuracy, this voltmeter will automatically move the decimal point position according to the different measured voltages.

When measuring voltages below 10V, display two decimal places after the decimal point;

When measuring voltages greater than 10V, display one decimal place after the decimal point.

It can meet both the measurement accuracy needs of battery users and the need to measure higher voltages.

This voltmeter can be used to measure the voltage of 18650 batteries, lithium batteries for mobile phones, nickel hydrogen battery packs, and other battery packs, as well as the voltage of batteries for motorcycles, cars, and other purposes. It can also be used for other voltage measurement purposes
