The Sound Level Meter Model CA832 is
designed to assess sound ambiences or nuisances in accordance with
international safety and quality standards. It complies with
standard IEC 651.
The Model CA832 is a portable, compact instruments with a 2000-count
backlit LCD. It is designed for simple, one-hand operation and may
be fitted on a tripod for long duration measurements. It features
two weighting curves A and C for measurement integrating the
sensitivity of the human ear according to sound frequency. Curve A
is the general-purpose curve in an industrial environment, and C is
more suited in presence of low frequency sounds. Also, mode "F"
(fast response time) corresponds to the response time of the ear.
Mode "S" (slow response time) will be used to obtain a uniform
reading when the sound signal level shows fluctuations.
