TAL
ISM - Integrating SLM measures LEQ, SEL, Min, Max,
Peak, with all weights (A, C, Flat) and with all
detectors (slow, fast, and impulse) simultaneously.
Includes a high and low measuring range.
îš— îš— îš— îš—
SSA - Sound spectrum analyzer measures LEQ, SEL,
Min, Max, Peak, with all weights (A, C, Flat) and with
all detectors (slow, fast, impulse, peak and Leq)
simultaneously plus 1/1 and 1/3 octave data stored in
time and interval histories at storage rates as fast as 8
times per second. Included are Ln data showing 6 Ln
values, a graph of L1 through L99 (broadband) and
spectral Lns. Wind and Tach data with external
transducers.

LOG - Logging SLM measures LEQ, SEL, TWA, MIn,
Max, Peak, with all weights (A, C, Flat) and with all
detectors (slow, fast, and impulse) simultaneously.
Includes time history, interval history, exceedance
history, daily history, Ln percentiles, statistical data,
exposure, and dual SLM (current and overall). Wind
and Tach data with external transducers.
îš— îš—
RTA - High speed spectral data gathering of up to 400
spectra per second using Autostore function. Spatial
averaging of any number of spectra. Flexible triggering
for data acquisition. Performs RT60, RC NCB, HTL.
Exponential and linear detectors.
îš—
FFT- 400 line FFT with Hanning, Flat-Top or
Rectangular window, snapshot data storage, display
zoom with a factor of 2, 4, or 8. Count averaging (1 to
16384), measures THD. LInear units can be user
defined.
îš—
AUD - Audiometer testing for level, frequency,
linearity, THD, pulse, crosstalk, frequency modulation,
narrow band, broadband, and speech noise.
îš—
TAL - Performs complex tonality calculations required
by DIN 45681. Measures the frequency of a dominant
tone (F
T
), the level of the tone (L
T
), the bandwidth of
the tonal group (F), the level of the group (L
G
), and
difference of the two levels (L
T
- L
G
). SLM measures
L

, and LCeq -
L
Aeq. A snapshot history is provided to store and
display data from the various modes.
