Wire Definition Introduction:
XH-2.54-3P red, black and yellow wire (thin wire Total length: 155mm)
Thin red wire: positive pole of the working power supply, can not be connected to the power supply above 30V.
Thin black wire: negative pole of the working power supply, and thick black wire site, do not need to be connected when sharing power supply.
Thin yellow wire: voltage test line, connected to the positive pole of the test circuit power supply.
VH-3.96-2P thick red and black wires (thick wire total length: 165mm) current test line
Thick wire parallel shunt resistance, can not be directly connected to the power supply poles, will be short-circuited!
Thick red wire: current test positive pole, string in the negative end of the load, connect the broken line after the first break!
Thick black wire: current test negative pole, connected to the negative pole of the power supply, connected to the broken line after the first break!

Package include:
1*Digital voltage current power meter
1*XH-2.54-3P Red, black and yellow wire
1*VH-3.96-2P Coarse red and black wire
