Method of Wiring: 
Red: Power Supply+ (DC 5-30V) 
Black: Power Supply -, Measure - 
Yellow: Measure + 
NOTE: 
The voltmeter needs isolated power supply. Power supply range is DC 3.5-30V. when black wire and red wire are switched to with the power supply, the voltmeter will display 0.000 (when the measuring line is dangling ,the voltmeter will display one or two base). Yellow wire and black wire will be switched to the measurement circuit. the measured voltage range is DC 0-33.000V. 

Package Includes: 
1x Digital LED Voltmeter
