It screws into your mod and then you put your topper on it and it displays the amps that are being drawn. I believe that's how it works. It's not a multimeter, I already use one to check for shorts, etc. It would be nice to have a real time amp meter ( if there is such a thing). Finally if there is such a device, where would I find it?
