SVANTEK 977W User Manual
1. INTRODUCTION
The
SVAN 977W
is an all-digital, Class 1 Sound & Vibration level meter (SLM
and VLM) as well as a real time 1/1 or 1/3 octave
analyser. The instrument is
designed for general acoustic and vibration measurements, environmental
monitoring, occupational health and safety monitoring.
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
,
Ltm5
,
LN%
,
LR15
,
LR60
,
Ovl
,
Peak
,
Max
and
Min
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 external 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:

and

for general vibration
measurements (like acceleration, velocity and displacement); are available with
this instrument.
Using the computational power of its digital signal processor the
SVAN 977W
instrument can, simultaneously to the meter mode, perform the real time
1/1 Octave
or
1/3 Octave
analysis including calculations of statistical levels.
The instrument conforms the WELMEC requirements for built-for-purpose
measuring instrument (type P) for acoustic measurements.
Time domain waveform signal recording on the external SD-card is available as
an option and advanced trigger and alarm functions are available in the standard
version of this instrument.
A fast USB 1.1 interface (12 MHz) creates a real-time link for the PC "front-end" application of the
SVAN 977W
instrument. With the use of optional interfaces (RS 232) the instrument can be remotely controlled from the PC
with the use of
+
software.
SVAN 977W is equipped with
Bluetooth
®
1
v.2.0+EDR module and can be remotely control by the
SvanMOBILE
Android platform smartphone application.
Working as a part of SV 277PRO monitoring station, equipped with 3G modem, SVAN 977W can transfer
measured data via Internet to the 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
extended 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.
Robust and lightweight design enhances the exceptional features of this new generation sound and vibration
instrument.
