The instrument can work in dc4-28v, but it will be hot when it is above 12V and reduce the accuracy and life. Please use 5-12V power supply.
Wiring method:
There are two sets of lines
Three of the finer A: groups,
Two thick B: group,
Group A:
black wire: power supply negative pole
Red wire: power supply positive. Warning: the maximum can only be connected to 28V, more than damage
Yellow wire: connected to the positive electrode needed to measure voltage
Group B:
black wire: the negative electrode of the tested power supply
Red wire: the negative electrode of the load to be measured. Warning: not connected to the power supply positive pole,
