I totally made a bad assumption!
When doing the original Set Measurement Level, i was reading the amount shown in the big black letters at the left of the REQW screen, assuming that this was a straight reading from the RS meter... which it obviously wasnt.
Now then! ... i went and looked at the SPL meter, and did both the set measurement level, and set input volume tests correctly (i hope!) and i'll move onto the next ones here shortly.
Will update if need be
thanks again, man!
