hi,
black lead to the middle socket, red lead to the left socket, turn the selector clockwise till it points at 10a. This will give you amps up to a maximum of 10 amps.

connections: black lead on positive battery terminal, red lead on the wire that normally connects to the battery positve, and turn on, read the amps.

note: when reading resistance make sure the red lead is in the right socket and touch the leads together before using them, you will get a zero resistance, this proves the unit is working, then connect to the thingy you want to test resistance in.

Hope thats clear?
