Recently I've started bring a Mel Meter to the party, and I find myself a little perplexed by the results it brings back. For a start it seems more sensitive. But more than that, it seems to pick up a lot that the DT-1130 doesn't. But the DT-1130 seems to pick up a lot that the Mel Meter isn't particularly interested in. I suppose I can use them together as necessary, but I'd like to have a full understanding of the differences. Hopefully someone can explain this to me in a way I can grasp.
My guess is that it's to do with the frequency of the EMF, I think the Mel-8704 goes down to 30MHz? This steps outside my understanding for now, and is what I'd like to discuss. A basic how-it-looks is that the DT-1130 doesn't read anything straight out the door of a microwave oven but it drives the Mel-8704 insane. Yet if I shove their faces into a domestic power outlet, the DT-1130 is the one that sounds the alarm, while the Mel-8704 barely registers anything above baseline.
