REAL TIME ANALYSER
INSTRUCTION
MANUAL
INSTRUMENT SOFTWARE VERSION 1.2
A sound level meter with built-in real
time analyser capabilities. Parallel
octave lters are standard (optional
in some markets), but the impressive
list of optional extensions include
sound power calculations, third
octave lters and statistics in every
frequency band, multispectrum and
reverberation time measurements.
The instrument logs level vs. time
(optional) and when it is equipped
with multiple time constants and
the enhanced prole extension, a
multitude of functions is logged si-
multaneously. The 120 dB dynamic
range eliminates the need for range
setting. A large memory and high-
speed data transfer rates complete
our user-friendliest solution to date.
