Finding one of the very high powered DBS satellites (those circular ones from Dish or Direct) is easy.
Getting on-target with an actual FTA bird it a bit trickier.
Also, those $10 sat meters aren't a lot of good .
...unless you happen to have a DBS satellite at the same orbital location [91°w, or 101°w, maybe?]
You'll need to set up your receiver with a transponder that's on the bird, and then use the Quality meter on the receiver to aim your dish.
There have been plenty of discussions on how to aim a dish.
So, I won't repeat all the minute details.
(but don't forget to set the skew, too)
edit:
Oh, "motorized", eh?
Well, there are about 100 things to get right, and a first-timer is likely to screw up at least half a dozen of 'em.

I'd really suggest you set up the dish without the motor to learn the basics of the dish and especially the receiver.
Then, after a week or so, try to integrate the motor with what you've learned.
