Specification:
Origin: Mainland China
Type: Module
Condition: New
Model Number: Mini Digital Voltmeter
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, easy and simple wiring, convenient to access the car/battery car/motorcycle car line;
3. With reverse connection protection function, the line will not be burned when connected to the reverse, with fine-tuning function;
4. Pay attention to the use of input voltage can not exceed 40V, otherwise there is a risk of burning.
5. When the voltage is lower than 3.0V, the display brightness will be dimmed, but does not affect the correct measurement. 
6. When measuring voltage below 10V, it will display two digits after the decimal point; when measuring voltage above 10V, it will display one digit after the decimal point.
That can take care of the battery users of the measurement accuracy needs, but also can take care of the measurement of higher voltage needs
Working voltage: DC2.5~40V (with reverse connection protection)
Detection voltage: DC2.5~40V
Working current: <30mA
Display: 0.28 "LED, red blue green yellow (colour selectable)
Measurement rate: ≥200mS/time
Measurement accuracy: 3 thousandth
Extreme working conditions:                                                                            
Low working voltage: +2.4V
Operating voltage: +40V
Operating temperature: -10~+65℃
Working humidity: 10~80% (no condensation)
Working air pressure: 80~106kPa
Sunlight exposure: no direct exposure
Best measurement accuracy, this voltmeter will automatically move the position of the decimal point according to the different measuring voltage
When measuring voltage below 10V, two digits are displayed after the decimal point.
When measuring voltages greater than 10V, one decimal point is displayed after the decimal point.
That is to take care of the battery users of the need for measurement accuracy, but also to 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 battery packs and other battery packs.
As well as motorbike, car and other battery voltage, can also be used for other voltage measurement purposes.
Main features:
1. Good stability and high measurement accuracy
2. Standard size, easy to install.
3. the power supply adopts polarity protection line

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
