INTRODUCTION
The
SV 104
instrument is a revolutionary new approach to occupational health and safety noise
monitoring offering
voice comments
,
audio events recording
and
vibration shock detection
functions
which are new and useful concepts in an instrument of this size. It is a cable-free dosimeter and is typically
attached to the user’s shoulder, close to the ear using the mounting clips supplied.
This personal dosimeter has an
incredibly robust
1/2" MEMS microphone (part number
SV 27)
enabling easy and automatic calibration using most commonly available acoustic calibrators.
The class beating, high resolution,
amazing colour
OLED
screen displays information in both text and
graphical form and offers excellent visibility in dark sites as well as in full daylight conditions. This makes
taking noise measurement a real pleasure.
Three independent acoustic profiles
allow parallel measurements with separately defined filters
and RMS detector time constants. Each profile provides an extensive number of results (like
Leq, Lmax,
Lmin, Lpeak, L, LE,…
). All required weighting filters (
A
,
C,
Z
) can be calculated in parallel.
For instance, it is trivial to set one profile to monitor noise parameters using the ACGIH (American
Conference of Governmental Industrial Hygienists) preset, second profile set to OSHA HC (Occupational
Safety and Health Administration - Hearing Conversation) preset and simultaneously monitor noise with the
OSHA PEL (Occupational Safety and Health Administration
– Permissible Exposure Level) settings.
Using the computational power of its digital signal processor the
SV 104
instrument can
simultaneously measure the dosimeter results and perform real time
1/1 Octave
analysis including the
calculations of the statistical levels.
An inbuilt tri-axial accelerometer for
vibration shock detection
firmly places
SV 104
as both the most
technically advanced and the most robust personal dosimeter out there.
Advanced
time history logging
for each profile provides safe and complete information about
measured signal in the internal
large
8GB memory
.
The instrument is powered from internal new generation Ni-MH
rechargeable batteries
offering circa
40 hours
1
of continuous operation. This new cell technology offers up to
1800 charge cycles
in comparison
to standard maximum 500 cycles. Low battery self-discharge is about 3% per month in comparison to 40%
per month in standard NiMH technology. The
powering and charging of the instrument from the USB
interface is provided which also enables easy data exchange connection between the
SV 104
and a PC
without the requirement of a special docking station.
The instrument works with
Svantek’s specialist health and safety software package -
Supervisor
,
and also with the full analysis package
SVAN PC++
.
Robust and lightweight design including innovative
magnetic mounted windshield
enhances
the exceptional features of this new generation instrument. Add to it the
automatic calibration
feature and
one can say: “Never before has a noise dosimeter been so accomplished yet so affordable, making your
measurements more
accurate and reliable than ever before
”
.
To get started quickly with the
SV 104
, the first part of the manual describes basic noise dosimetry
information followed by a guide to setting up the dosimeter and running measurements.
