I was on the search for a logging multimeter for ages. A friend mentioned he'd gotten this "Mooshimeter" - a meter I'd never heard of. I asked around about it, got in touch with James, and he sent over a refurbished unit for me to test and play with. Now, I'm not electrical engineer - I discussed that with him and I'll say it up front to you. This isn't going to be that kind of test. Consider it an overview, a how-it-works. And if nothing else, a bunch of photos of the unit!
