Yeah, I measured it too that night. Guess I'd never thought about it, and always used the mid range. I believe the reasoning behind it is that the user gets a better resolution for their particular measurement by having three ranges; the max and min outputs are relative to the range. It's akin to having a pad switch on a mic or preamp so that you are able to take advantage of the range that best fits your application. That's what I'm thinking anyway.
