Sound level meter using manual control

level meter. Sound at the test box reference microphone and the coupler microphone may be analyzed by 1/12th

octave, A-weighted or C-weighted filters. A and C-weighted measurements are limited to frequencies above 100

Hz and the averaging time and update rate are 384 ms.
