SVAN 977C User Manual
1 INTRODUCTION
SVAN 977C is an all-digital, Class 1 Sound & Vibration level meter designed for
general acoustic and vibration, environmental noise, occupational health and
building acoustic measurements.
Three acoustic or vibration user configurable profiles allow parallel
measurements with independently defined frequency filters and RMS detector
time constants. Each profile provides significant number of results (like
Spl , Leq,
Sel , Lden , LEPd , Ltm3 , LTeq , Peak , Max and Min as well as ten statistics, two
rolling Leq, expected Leq value, standard Leq deviation and noise criterium and
noise ratio indexes
in case of sound measurements or RMS , Ovl , Peak , P-P in
case of vibration measurements). Advanced time history logging for each profile
provides complete information about the measured signal using the SD-card
fitted in the bottom of the meter and can be easy downloaded to any PC using
the USB interface and + software.
All required weighting filters: A , B , C , Z , U , AU and LF for sound measurements
and HP1 , HP3 , HP10 , Vel1 , Vel3 , Vel10 , VelMF , Dil1 , Dil3 , Dil10 and Wh for
general vibration measurements (like acceleration, velocity and displacement);
are available with this instrument.
Using the computational power of its digital signal processor SVAN 977C can,
simultaneously to the meter mode, perform the real time
1/1 Octave or
optionally 1/3 Octave analysis including calculations of statistical levels or can
optionally perform FFT analysis.
The built-in frequency analyser offers 1/1 octave real-time analysis as a
standard feature and 1/3 octave and FFT as optional functions. The frequency
analysis is logged together with the time history of sound or vibration meter
results.
Time domain waveform signal recording on the SD-card is available as an option
and advanced trigger and alarm functions are available in the standard version
of this instrument.
For building acoustic applications, SVAN 977C offers Reverberation Time
measurements (RT60) option working with the
BA Assistant application for
smartphones.
SVAN 977C enables also STIPA calculations in accordance with IEC 60268-16:2011 as optional function.
A fast USB 1.1 interface (12 MHz) creates a real-time link for the PC "front-end" application of SVAN 977C. With
the use of optional interfaces (RS 232) the instrument can be remotely controlled from the PC with the use of
+ software.
SVAN 977C is equipped with Bluetooth
®
1
v.2.0+EDR module and can be remotely control by the SvanMOBILE
and BA Assistant smartphone applications.
Working as a part of the SV 277 monitoring station, equipped with 3G modem, SVAN 977C can transfer
measured data via Internet to PC with the use of +_RC option or via SvanNET web service. The
instrument can be fully remotely controlled via these interfaces. The instrument has advanced alarms features,
enables the user notification about exceeded threshold levels by SMS or mails.
The instrument is powered from four AA standard alkaline or rechargeable batteries (i.e. NiMH
– a separate
charger is required). Powering the instrument from the External DC power source or the USB interface is also
possible.
