Description

The CA832 digital sound level meter is designed to measure ambient
sound in accordance with safety and/or work standards.
Complies with standard IEC 651.
The professional and domestic applications are numerous: measuring the
sound levels in factories, schools, offices, airports, studios, auditoriums,
etc.
The CA832 is a portable, compact instrument with a 2000 point display
operable in one hand and may be fitted on a photographer's type tripod for
long duration measurements.
The CA832 is used to measure sound levels from 37 to 130dB in 3 ranges:
37-80dB, 50-100dB, 80-130dB.
This meter features 2 weighting curves (A and C) for measurement inte-
grating the sensitivity of the human ear according to sound frequency.
Curve A is a general-purpose curve typically used in a industrial environ-
ment, and C is more suited for 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.
