Misleading Instructions
The sheet that is included with this very nice little unit is useless. No where does it state or show that the load side (yellow lead) must be attached to the negative side of the load. Also all of the leads must be used/connected. If you do this the unit performs well.

Great meter
Meter works great, surprising accurate. Current reads as low as 50 milliamps. Mine connected to a separate 12v dc power source.

A customer from Norristown, Pa
diagram wrong
I agree with the assessment, if you wire it according to the diagram, either supplied or the PDF here, it won't work!

Randall Moon from TULLAHOMA, TN USA
ramote supply must be isolated
I cut up a 5 volt wall wort and used it to power the meter so the 2 black wires are isolated from each other. works great.
