Graeme, surely the meter came with a booklet of instructions? Just from the brief info shown on the site it would appear that there are only two ranges, 30-100dB and 60-130dB, but there would have to be a switch to choose between the two. The comment that you quote from the Blu-ray forum apparently refers to a RadioShack meter or similar which has a relatively narrow range of +/- 10dB around the set number, which is on a round dial marked in 10dB increments from 60-120dB(allowing measurements from about 50 to 130db by varying the range setting). If your meter can in fact measure from 30 to 100dB in one range without having to change some setting, then of course that's even better than having to make a setting that's within 10dB of the sound level to be measured.
You sound as if everyone should know these things? I have absolutely no clue what so ever with this, I have never used one in my life and have never even seen a Radio Shack SPL let alone used one.
It's a little hard when you don't understand what you are reading. It may as well be in Japanese.
I'm trying to learn, but maybe I should be a lot more knowledgeable before I ask a question.
