0.28 Inch 2.5V-40V Mini Digital Voltmeter Voltage Tester Meter Red/Blue/yellow/green LED Screen Electronic Parts Accessories | Инструменты

Two wires, convenient and simple wiring, easy to connect to the car / battery car / motorcycle internal circuit, with reverse connection protection function, the reverse connection will not be burned, with fine adjustment function;

 Function introduction: 1. Range: 2.5-30V (red) 2.6-30V (yellow) 2.6-30V (green) 3.2-30V (blue) 2. Equipped with two wires, the wiring is convenient and simple, and it is convenient to connect the car / battery car / Motorcycle internal circuit; 3. With reverse connection protection function, the reverse connection will not be burned, with fine-tuning function; 4. Note that the maximum input voltage cannot exceed 40V, otherwise there is a danger of burnout. 5. When the voltage is lower than 3.0V, the display brightness will be dimmed, but it will not affect the correct measurement. 6. When measuring the voltage below 10V, two digits will be displayed after the decimal point; when measuring the voltage above 10V, one digit will be displayed after the decimal point. It can take care of the needs of battery users for measurement accuracy, and can also take care of the need to measure higher voltages.

For the best measurement accuracy, this voltmeter will automatically move the position of the decimal point according to the measured voltage.
When measuring voltage below 10V, two digits will be displayed after the decimal point;
When measuring voltage greater than 10V, one digit is displayed after the decimal point.
 It can take care of the needs of battery users for measurement accuracy, and can also take care of the need to measure higher voltages.
This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, nickel-metal hydride batteries and other battery packs.
 As well as the voltage of batteries such as motorcycles and automobiles, it can also be used for other voltage measurement purposes.
