0.28 inch Digital Display DC Voltmeter 2.5-30V Adjustable 2 Wires Car Mobile Power Voltage Tester Red Green Blue Yellow Voltage Meter 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, convenient and simple wiring, easy access to the car / battery car / motorcycle inner 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 voltages below 10V, two digits are displayed after the decimal point; when measuring voltages above 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. Features: Working voltage: DC2.4 ~ 40V (with reverse connection protection function) Detection voltage: DC2.4 ~ 30V Working current: <30mA Display mode: 0.28 "LED, red blue green yellow (color optional) Measurement rate: ≥200mS / time Measurement accuracy: 3 ‰ Extreme working conditions: Low working voltage: + 2.4V Maximum working voltage: + 40V Working temperature: -10 ～ + 65 ℃ Operating humidity: 10 to 80% (non-condensing) Working pressure: 80 ～ 106kPa Sun exposure: no direct exposure Measurement accuracy. The 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
