Weighting filter
Sound measurements:
• Z according to IEC 61672-1:2013 for Class 1,
• A according to IEC 651 and IEC 61672-1:2013 for Class 1,
• C according to IEC 651 and IEC 61672-1:2013 for Class 1,
• B according to IEC 651 for Class 1,
• U according to IEC 61012:1990 for Class 1,
• AU according to IEC 61012:1990 for Class 1,
• D according to BS 5721:1979,
• HP high-pass filter,
• LF low frequency (20-200 Hz) real-time band pass filter.
Vibration measurements:
• acceleration measurements: HP, HP1, HP3, HP10, Wh,
• velocity measurements: Vel1, Vel3, Vel10 and VelMF,
• displacement measurements: Dil1, Dil3 and Dil10.
Characteristics of these filters are given in Appendix C.
RMS detector
The Detector position defines the type of the
exponential RMS detector which is applied to
RMS based results (Leq, SEL, LEPd, Lden,
Ln results for sound measurements and RMS
results for vibration measurements) provided
that the RMS detector in General Settings
was set to exponential (path: <Menu> /
Measurement / General Settings /
RMS Integration: Exp) and always applied to
Lmax, Lmin, Spl, Ltm3, LTeq results for
sound measurements and Max results for
vibration measurements.
Available exponential RMS detector types
(time constants): Impulse, Fast and Slow for
sound measurements and 100ms, 125ms,
200ms, 500ms, 1.0s, 2.0s, 5.0s, 10.0s for
vibration measurements.
You can easily access the Profiles screen
from the result view screen. Select some
profile field (for example, P(1)) with the â–² / â–¼
or â—„ / â–º key and press <ENTER>.
4.4 CONFIGURING DATA LOGGING – LOGGING
Summary Results (Peak, Max, Min, Spl, Leq, SEL, Lden, LEPd, Ltm3, LTeq, 10 x Ln, EX, SD, LR1, LR2,
OVL, NC, NR for Sound measurements or RMS, Ovl, Peak, P–P for Vibration measurements as well as 1/1
octave, 1/3 octave or FFT spectra with Total results and meteo results) are measured and saved in the file with
the step defined by the Integration Period parameter as many times as defined by the Repetition Cycles
parameter (path: <Menu> / Measurement / General Settings).
