Introduction to wire definition:

XH-2.54-3P red, black, and yellow wire (thin wire, total length: 155mm)

Thin red wire: positive pole of working power supply, cannot be connected to power supply above 30V

Thin
black wire: the negative pole of the working power supply, and the
thick black wire at the construction site, do not need to be connected
when sharing the power supply

Thin yellow wire: voltage test wire, connected to the positive pole of the test circuit power supply

VH-3.96-2P thick red and black wire (thick wire total length: 165mm) current test wire

Thick
wires connected in parallel with shunt resistors cannot be directly
connected to the two poles of the power supply, as they will cause a
short circuit! ! !

Thick
red wire: The positive electrode of the current test is connected to
the back end of the negative electrode of the load. When the wire is
disconnected, connect it last and disconnect it first.

Thick
black wire: the negative pole of the current test, connected to the
negative pole of the power supply. When the wire is disconnected,
connect it first and then disconnect it.
