Even if you don't own one, you can download the user manual for the Spyder Lenscal, which contains some useful pointers on the procedure (like what the optimal testing distance is)

You don't need a test chart. Just focus on something at an angle with the widest aperture and take some test shots and adjust until it's the best you can get it.
