I never use such tools, it's rubbish, because the values they give are never accurate to the actual marks on the dish.
This is what I do, I put the amount of LNB brackets on the support that I am planning to use. Then the middle one I put on mark 0, or if there isn't a middle one (even number of LNB's) I fix one at -10 and one at +10. Insert the LNB's, add the cables but don't screw anything yet. Then, probably you'll know the coarse direction the dish should be pointed to (looking at other dishes in the neighbourhood, or you previous one), select a transponder your exepect and then simply turn the dish until a lock occurs. For smaller dishes I've even done it without mounting the dish, carrying it myself When lock, scan the transponder so you know you have the correct position. From that point you can optimise this LNB a bit (dish up/down, LNB skew). Now you can do the same with the two outer LNB's, but don't turn the dish, shift the brackets instead. When lock, turn the dish until both outer LNB's have max reception. When that's done, you can do the rest of the LNB's. It will probably take a few rounds to get it optimal, I do it once a year and then it takes a whole day to get them all right.
