If you want to add a satellite or transponders for a satellite, you probably have to do it yourself, use one of the memory positions.
For general alignment, use the spectrum mode, on page 26 and 27 of the manual satelliteman links to. Set to spectrum mode, set to satellite band and widen the spectrum to full, then as you move the dish you will see the spectrum change as you pass the different satellites, can't give you any reference pictures, as the spectrum will look different from the UK, but for example, Astra 19.2 on low band vertical, will have have a lot of very sharp spikes, set between the rounded and lower digital humps, whereas Hotbird will be a solid row of rounded humps across the screen.
Read page 61 of the manual, looks like the meter in picture mode, should show NIT, giving you channel and possibly satellite details.
You have a superb meter there, but it will take a long period of learning and practice to get the most out of it.
