I got the videos. They're good.
Actually watched most of them before I ordered the unit.

I understand the manuals and the videos pretty well. I'll be starting a calibration run this evening after dinner settles.

I am the kind of person who likes to understand the principles on which something works instead of learning the steps by rote.
If you just learn the steps, it's harder to figure out a problem you were never taught to handle. If you learn the principles, you can figure out how to handle anything that comes your way.

The instruction manuals are good and they are easy enough to understand. I figured, instead of asking questions via e-mail, I'd ask in the forum.
First, everybody can share the knowledge gained instead of just one or two people.
Second, getting input from more than one source is almost always better. That's what forums are for. Right?
