*1 : 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.
*2 : Error calculation method, the percentage of maximum range, plus the number in brackets
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, otherwise burned
