Best leave it alone; it will taste crap at this stage. Even after you prime and bottle or keg it, you really want to wait about four weeks before it's worth drinking.
The less fiddling the better, you dont want to risk infecting the stuff. I leave mine for a least a 10, usually 14 days. Then just take the reading before bottling or kegging.

Thanks all for your help and encouragement.
