| SPL Meter Lesson 1 Hi. I'm a bit confused with the analog meter on my old RS SPL. The scale begins on the Left side at -10db, is 0 in the center then goes to 6DB at the Right end. I understand that if the range is set to 80, and the reading is 0, 80 is the measurement. If I wanted to read 75DB while in the 80db range it should point to around -2.5 ... am I right? -Steve | |||

| Re: SPL Meter Lesson 1 No, it should point to -5. The magic formula is: Selected range + (read value) So in your example you have 80 + (-5) = 75 You could also measure 75dB in the 70dB range, the needle would then read +5. | |||
