I am still trying to grasp this SPL thing, I wanted to try and setup the EP500 today and was reading about it on http://forum.blu-ray.com/showthread.php?t=38765 and it stated, Set the db range on the meter to “75" or “80".

How do I do that? I don't see an option on my SPL to set a range.

This is the SPL meter I am using https://www.instrumentchoice.com.au/store/index.php?_a=viewProd&productId=64

Any advice would be very welcome
