How is this meter supposed to be used?
I am measuring current in zip cord, and I do have available the
negative wire, one side of which runs to system ground (a lead-acid
battery negative terminal).
However, when I tried the meter on the black wire in this way, it
showed "-00.4" amps with no current imposed on the shunt and supply
current to the meter limited to 0.040 amps. So just using it on the
ground wire, and having one side of the shunt and the 5V negative
commoned did not work properly.
