0.28 Ultra-small DC Voltmeter Digital LED Display Adjustable

Product information:

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, and it is easy to connect to the car/battery car/motorcycle interior line;
3. With reverse connection protection function, the wire will not be burned when reversely connected, and it has a fine-tuning function;
4. Note that the input voltage cannot exceed 40V, otherwise there is a danger of burning.
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 voltage below 10V, two digits are displayed after the decimal point; when measuring voltage above 10V, one digit after the decimal point is displayed. It can not only take into account the needs of battery users for measurement accuracy, but also take care of the needs of measuring higher voltages.
Working voltage: DC2.4~40V (with reverse connection protection function)
Detection voltage: DC2.4~40V
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 operating voltage: +2.4V
Working voltage: +40V

Measurement accuracy, the voltmeter will automatically move the decimal point position according to the difference of the measured voltage.
When measuring voltages below 10V, two digits are displayed after the decimal point;
When measuring voltages greater than 10V, one digit is displayed after the decimal point.
It can not only take into account the needs of battery users for measurement accuracy, but also take care of the needs of measuring higher voltages.
This voltmeter can be used to measure the voltage of 18650 batteries, cell phone lithium batteries, NiMH battery packs and other battery packs.
As well as the voltage of motorcycles, automobiles and other batteries, and can also be used for other voltage measurement purposes
