0.56 inch 0-100V Three Wire LED Display Digital DC Voltmeter-Red

0.56 inch 0-100V Three Wire LED Display Digital DC Voltmeter Red 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 negative pole and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage. While measuring the supply voltage of another source make sure that the negative pole is joined common. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection. To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltage. 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. This dc digital voltmeter can be used to measure the storage battery’s voltage 0-100v in motorcycles and cars and also can grasp the storage battery status. It also can be used to measure other DC voltage. This voltmeter can operate on versatile 4.5V to 30 VDC range is the voltmeter maximum operating limited voltage, please leave enough margin (i.e. do not reach up to last limit which is 30V ) when working, to avoid voltmeter permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage. Very bright and decent LED Display is ready to measure the dc voltages in the range of 0-100V. Features : Very small and lightweight voltmeter module. Very handy and easy to use. Red LED display. Best operates in the working voltage range of 5V to 24V Recommended device Operating Voltage: 5V DC Matt finish Display glass makes display Digits more Lucid in the daytime. Specifications: Voltage Measuring Range: 1V to 100V DC Operating Voltage (VDC): 4.5 ~ 30 Current Consumption (mA): ≤40 Display ON Voltage (V): 3 Display LED Color: RED Accuracy: 1V Wires: 3 Cable Length (CM): 20 Refresh Speed (ms): 200 (one time) Operating Temperature (°C): -10 to 60 Height (mm): 28 Length (mm): 48 Width (mm): 16 Weight (gm): 13 Connections : Red Wire: Positive of the Power supply Black Wire: Negative of the Power supply and also used as the negative of the measurement voltage source Yellow/White/Blue: Positive of the measurement voltage source. Note: Consider 1V voltage drop at voltmeter itself, as we observed it while testing this Voltmeter. Product Image may vary in terms of colour 3rd Wire and PCB or PCB-layout as per the version update from the manufacturer. Package Includes : 1 x 0.56 inch 0-100V Three Wire DC Voltmeter-Red
