Wire Descriptions: The red wire is to connect to the positive pole, the black wire is to connect to the 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. This voltmeter can be used to measure the storage battery’s voltage upto 100Volts in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other DC voltages. Very bight and decent LED Display is ready to measure the dc voltages in the range of 0V to 100V. Note: Consider 1V voltage drop at voltmeter itself, as we observed it while testing this Voltmeter. Product Image may vary in terms of color 3rd Wire and PCB or PCB layout as per the version update from the manufacturer Specifications: Very handy and easy to use. Red LED display. Best operates in the working voltage range of 5V to 24V Matt finish Display glass makes display Digits more Lucid in the daytime. 100% Brand new and high quality. .Very small and lightweight voltmeter module.
