Specification: Origin: Mainland China Type: Module Condition: New Model Number: Digital Voltmeter Function Introduction: 1. Range: 0-100V 2. Equipped with three wires, easy and simple wiring, convenient access to 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 the highest input voltage can not exceed 100V, 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. 7. That is, it can take care of the battery users' need for measuring accuracy and the need for measuring higher voltage. 8. Working voltage: three-wire DC2.4~40V (with reverse connection protection) 9. Detection voltage: three-wire r0.0~100V 10 Working current:
