INTRODUCTION
Now, the
SV 104BIS
instrument is even more revolutionary approach to occupational health and safety noise
monitoring offering voice comments , signal 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 ST 104B ) 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) pre-set, second profile set to OSHA HC (Occupational Safety and
Health Administration - Hearing Conversation) pre-set 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 104BIS instrument can simultaneously
measure the dosimeter results and perform real time
1/1 Octave & 1/3 Octave analyses including calculations
of statistical levels.
An inbuilt tri-axial accelerometer for vibration shock detection firmly places SV 104BIS as both the most
technically advanced and the most robust personal dosimeter out there providing also information on the time
when dosimeter is not used by the worker.
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 Li-ion
rechargeable batteries
offering circa
45 hours 2 of continuous operation. Ultra-low battery self-discharge is about 1% per year. The powering and
charging of the instrument is possible with the use of SB 104B-1 or SB 104B-5 docking station with the USB
interface enables easy data exchange with a PC.
The instrument works with Svantek dedicated health and safety software packages
–
Supervisor , mobile
Assistant , and also with the full analysis package + .
Robust and lightweight design and Low Energy Long Range Bluetooth
®
Smart wireless interface enhances
the exceptional features of this new generation instrument. Add to it the
automatic calibration
feature and
one can say: “N
ever 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 SV 104BIS, the first part of the manual describes basic noise dosimetry information
followed by a guide to setting up the dosimeter and running measurements.
