Mosiee 0.28-inch LED Minimun Digital Voltmeter DC2.5-40V reverse connection protection

Mosiee 0.28-inch LED Minimun Digital Voltmeter DC2.5-40V reverse connection protection Description

Feature *The wiring is convenient and simple. It is equipped with two wires, which is convenient and simple in wiring, which is convenient to access the inner line of cars/battery cars/motorcycles. * It has anti -connection protection functions, and the wire connection will not be burned and has a fine -tuning function. Pay attention to the use of the input voltage cannot exceed 40V, otherwise it will be in danger of burning. When the voltage is lower than 3.0V, the brightness will become darker, but it does not affect the correct measurement. *Measurement accuracy, the voltage table will automatically move the position of the decimal point according to different measurement voltage. *When the voltage below 10V is measured, two digits are displayed after the decimal point; when the voltage of more than 10V is measured, a digit is displayed after the decimal point. That is, the need to take care of the measurement accuracy of battery users, and can also take care of the need to measure higher voltage. *This voltage meter can be used to measure the voltage of mobile phone lithium batteries, nickel -metal hydride battery packs and other battery packs, as well as voltage of batteries such as motorcycles and cars, and can also be used for other voltage measurement purposes.
