SOUND ANALYSER
INSTRUCTION
MANUAL
INSTRUMENT SOFWARE 4.0
A sound level meter with built-in real
time analyser capabilities complying
with international instrument stand-
ards. Parallel octave fi lters are stand-
ard (optional in some markets), but
the impressive list of optional exten-
sions include third octave fi lters and
statistics in every frequency band,
multispectrum, reverberation time
measurements, and recording for the
measured sound. The instrument logs
level vs. time (optional) and when it is
equipped with multiple time constants
and the enhanced profi le extension, a
multitude of functions is logged simul-
taneously. The more than 120 dB dy-
namic range eliminates the need for
range setting. A large memory, SD-
card and high-speed data transfer
rates complete a user-friendly solution.
