Turn the power on and select the desired response Time and
Frequency Weighting. If the sound source consists of short bursts or
only catching sound peak, set response to FAST. To measure

level, select A-weighting. For measuring sound level of loud sounds
with high bass content, select C-weighting.

Hold the meter comfortably in your hand, or fix to a tripod, and point
the microphone at the suspected noise source. The sound pressure
