This is a 0.28 Inch 0-100V Three Wire DC Voltmeter Blue.

This is a tiny and compact digital voltmeter with a blue The 0 to 100 V 0.28-inch Digital Voltage Tester DC VOLTMETER 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 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.

Very bright and decent  is ready to measure the dc voltages in the range of 0V to 100V. It is small in size and light in weight, quite easy and convenient to carry out. Its small size which is only 0.28″ with bright and sharp blue light visible LED display, easy to read even in dim light and low operating voltage.

This 0.28 Inch 0-100V Three Wire DCBlue can be used to measure the storagevoltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltages. 100V is the voltmeter’s maximum operating limited voltage, please leave enough margin when wo
