This is all new tiny and compact digital voltmeter with a RED LED Display. The 0.56inch 0-100V Three Wire DC Voltmeter Red 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.This voltmeter can be used to measure the storage battery’s voltage up to 100Volts in motorcycles and cars and also can grasp the storage battery’s status.It also can be used to measure other DC voltage.

This voltmeter can operate on versatile 4.5V to 30VDC range is the voltmeter’s 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’s 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 0V to 100V.
