Working Humidity 10-80% 0.28-inch Voltmeter Reverse Connection Protection

Features: *Simple wiring: The wiring is convenient and simple. It is equipped with two wires, which is convenient and simple in wiring, which is convenient to for access the inner line of cars/ cars/motorcycles. *Good protection: It has anti -connection for 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. *Automatic decimal-point adjustment: Measurement accuracy, the voltage table will automatically move the position of the decimal point according to different measurement voltage. *Adaptive precise: 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 users, and can also take care of the need to measure higher voltage. *Wide application: This voltage meter can be used to measure the voltage of for mobile phone / batteries, nickel -metal hydride packs and other packs, as well as voltage of batteries such as motorcycles and cars, and can also be used for other voltage measurement purposes.
