A weighting is commonly used for measuring general noise
levels. It emulates the response of the human ear.
C weighting is typically used for peak measurements and
more accurately characterizes low frequency noise.
3） Press the F/S button to select the desired response time.
“FAST” or “SLOW” indicator will appear on the LCD.
FAST sampling: once every 125 milliseconds.
SLOW sampling: once per second.
To measure a short sound burst or record a peak sound level,
use the FAST response time. For general sound level
measurements, use the SLOW response time.
4） Hold the instrument away from your body or mount it to a
tripod. Point the microphone at the sound source.
5） The LCD displays the current sound level reading. It is
updated twice per second.
Note: When using the instrument in windy conditions (greater than
20 mph) use the windshield ball to avoid inaccurate readings.
