In general you want to have the longest travel between pulleys move no more than 3/4" when you push on it fairly hard. The tool probably applies a calibrated amount of pressure and measures the distance the belt is deflected.
No, it is not an automatic tensioner. Its manual. The pulley is attached to a long bolt. I've already had trouble with a shop over-tightening the the previous belt. They ended up replacing the water pump. The over tight belt fried the bearing in about 2 days.
