The Analog Sound Level Meter is a
versatile device which measures sound
level in any acoustic environment. The
meter will enable you to easily measure
sound or noise levels that are loud or soft,
high or low-pitched, broadband, intermittent,
or in factories, schools, offices, airports,
sound studios, theaters, auditoriums,
automobiles, and in the home. This
precisely calibrated meter features a large,
easy-to-ready analog indicator and is
battery powered for convenient, portable
use.
INTRODUCTION
IMPORTANT NOTE
Continuous high pressure levels (>
100 dB) can permanently damage your
ears. Always set the volume accordingly
when testing. Continuous high pressure
levels can permanently damage your
loudspeakers.
Remember noise levels above 85 dB will
harm hearing over time. Noise levels
above 140dB can cause damage to
hearing after just one exposure.
The meter is calibrated before ex-factory
,using a standard accoustic calibrator
which generate "94dB" output .
We would recommend you to re-calibrate
the meter with a cycle one year .
