Three wire 0.28 inch dc 0v to 100v digital voltmeter

0.7 cm (0.28 inch) 0-100V Three Wire DC Voltmeter RED 

This is tiny and compact digital voltmeter with a yellow LED Display. The DC 0-100V 3 Wire RED LED Display Digital Voltage Voltmeter 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 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 voltages. 

This voltmeter can be used to measure the storage battery’s voltage 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 working, to avoid the voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage. 

Very bight and decent LED Display is ready to measure the dc voltages in the range of 0V to 100V.
