028 Inch LED Ultra Small 0 100V DC Digital Voltmeter Battery Voltage Tester for RC Model0 28 Inch LED Ultra Small 0 100V DC Digital Voltmeter Battery Voltage Tester for RC ModelThis is tiny and compact digital voltmeter with a red LED Display 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 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 negative pole is joined common No need to worry even if there is any connection mismatch of the wires the electric circuit wont be a boom because it features reverse polarity protection It requires an extra power supply of 0V to 100V To reach the best measurement accuracy this voltmeter will automatically move the decimal points 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 Very bight and decent LED Display 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 visibl
