    *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
