2.1.3 SVAN 958A
– Sound and Vibration Analyser
SVAN 958A
is a class 1 Four-channel Sound & Vibration level
meter as well as a real time 1/1 or 1/3 octave or FFT
analyser and
is a core of the SV 258 PRO system. Its role is to make
measurements and save results in files, as well as to control data
transfer via modem to the SvanNET web-server or directly to the
PC. Measurement results can be analysed later with the use of the
+ software.
There are 2 firmware versions for SVAN 958A:
•
standard firmware - SVAN 958A and
•
dedicated to building and ground vibration measurements -
SVAN 958AG.
The SVAN 958AG firmware simplifies setting up the station in
accordance to international and local standards such as
DIN 4150-3 or BS 7385-2.
The biggest advantage of this firmware is the real-time vibration
events assessment either with FFT or 1/3-octave analysis and
direct comparison to criterion curves on-site.
The SVAN 958AG firmware is described in Chapter
SVAN 958A has two input sockets: 4-pins Lemo compatible socket
type ENB.0B.304 for
Channels 1
–3
and TNC for
Channel 4
.
All sockets ensure IEPE power supply for the accelerometers or
microphone preamplifiers.
SVAN 958A, when it works with the monitoring station, is powered
from an external power supply via the
6-24V
socket.
Data transfer to the modem is via a
USB Host
socket, the serial
interface.
Other instrument sockets are not used in the SV 258 PRO system.
SVAN 958A can be easily removed from the case and used as an
independent hand-held sound or vibration level meter/analyser.

Note: As a part of the SV 258 PRO station SVAN 958A is powered from the external source and
doesn’t use its internal batteries. Internal instrument’s batteries must be removed for correct system
operation and safety reasons!
Note: The station is delivered without internal batteries inside the instrument. But if you use
SVAN 958A as a hand-
held instrument, don’t forget to remove batteries from the instrument every
time you put it back into the station slot.
To insert or extract batteries,
switch off the instrument, remove
the bottom rubber cover, unscrew
out the blanking plate and slide the
batteries out. Screw the clanking
plate and fix the rubber bottom
cover back on.
