This is tiny and compact digital voltmeter with redĀ LED Display. 0.28inch 3.5-30V Two Wire DC Voltmeter RedĀ Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!!
The red wire is to connect to the positive pole, the black wire is to connect to the negative pole. No need to worry even if there is any connection mismatch of the wires, the electric circuit wonāt be a boom because it features reverse polarity protection.
ThisĀ voltmeterĀ doesnāt need external drive working power, it can work with measuring voltage, the working voltageās range is 3.5-30V. To reach the best measurement accuracy, this voltmeter will automatically move the decimal pointās position according to the different measuring voltage.Ā When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point.
ThisĀ voltmeterĀ can be used to measure the storageĀ batteryās voltage in motorcycles and cars and also can grasp the storage batteryās status. It also can be used to measure other voltage. 30V is the voltmeterās maximum operating limited voltage, please leave enough margin when working, to avoid the voltmeterāsĀ permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.
Very bight and decentĀ LED DisplayĀ is ready to measure the dc voltages in the range of 3.5V to 30V.
