provided by the equipment may be impaired.
Note: The SV 104BIS dosimeter contains no user serviceable parts. Opening product case
invalidates the warranty.
Note: When in normal use, always fit the SA 122BIS windscreen provided and make sure there is
no display shipping protection foil in place. See Chapters 3.3 and 4.2.
Note: Under no circumstances should this equipment be cleaned using a solvent based cleaner (it
can affect the case polymeric materials). Clean it with water dampened cloth only.
Note: Battery power indicator - To improve accuracy of remaining battery life indicator, run the
dosimeter until it is fully discharged; then proceed with a full charge via the docking station.
The procedure is recommended before first use. Repeat this procedure every year of use
to maintain more accurate current battery condition indication.
Note: If the dosimeter is flooded / falls into water - the device loses the intrinsically safe guarantee
and cannot be used in potentially explosive atmospheres.
Note: The dosimeter should be periodically checked that it does not become unsealed, e.g. as
a result of a fall, because then it loses IP65 (Ingres Protection) rating.
Note: Dosimeter incorporates Bluetooth®1wireless communication operating in 2.4GHz RF band
and transmit power up to +9dBm.
Note: For air-transport turn off Bluetooth interface (Chapters 3.8.3, 6.3.9.4 and 7.8).

HAZARDOUS AREA INSTALLATIONS SPECIFIC INFORMATION
The SV 104BIS instrument is designed to be used in potentially explosive environments.
1. The equipment shall only be charged in non-hazardous area by manufacturer’s chargers
on a fireproof surface. The recommended charging docking stations: SB 104B-1 and SB 104B-5.
2. Whenever it is likely that the correct function or operating safety of the apparatus has been impaired,
it must be made inoperative and be secured against unintended operation.
3. The dosimeter should be mounted on conductive clothes and/or with direct contact with human
body. This assures a path to remove the accumulated electrostatic charge that could built-up on
dosimeter.
4. Some parts of the enclosure are non-conducting and may generate an ignition–capable level of
electrostatic charge under certain extreme conditions. The user should ensure that the equipment is
not installed or used in a location where it may be subjected to extreme conditions (such as high-
pressure steam), which might cause a build-up of electrostatic charge on non-conducting surfaces.
Additionally, cleaning of the equipment should be done only with a water dampened cloth.
5. Before entering hazardous zone check if there is no display shipping protection foil in place,
which is used on new products being sent to protect from accidental scratches. See Chapter 4.2.
6. The SV 104BIS instrument shall not be used in areas where a layer of coal dust may be deposited on
the enclosure.
7. The microphone windscreen and microphone should not be removed in a hazardous area.
8. The equipment may be used with flammable gases and vapours with apparatus Groups IIA, IIB and
IIC and with temperature classes T1, T2, T3 and T4.
9. The equipment is only certified for use in ambient temperatures in the range -10°Cto +50°Cand
should not be used outside this range.
10. If the equipment is likely to come into contact with aggressive substances, then it is the responsibility
of the user to take suitable precautions that prevent it from being adversely affected, thus ensuring
that the type of protection is not compromised. Aggressive substances e.g. solvents may affect
polymeric materials.
11. Any substitution of components may impair intrinsic safety.
12. Repair and battery replacement of this equipment shall only be carried out by the manufacturer
or by authorized and trained service personnel. Any adjustment, maintenance and repair of the
open apparatus under voltage must be avoided as far as possible and, if unavoidable, must be carried
out only by trained service.
13. Calibration with non-intrinsically safe calibrators must only be performed on the SV 104BIS in
a non-hazardous atmosphere.
14. The SA 123IS and SA 124IS optional mounting accessories are made of natural leather, stainless
steel and EN 1149 antistatic velcro. Because the EN 1149 test may not reflect the conditions of end
use, those responsible for Health & Safety in the work environment should perform an in-use test
to determine if the additional accessories being considered as part of the total earthed system,
is compatible with their requirements for protection against electrostatic discharge.

SPECIAL PRECAUTIONS WHEN USING AND CHARGING LITHIUM
BATTERIES
SV 104BIS instrument contains extremely high energy density lithium-ion cell. Use special caution when
working with lithium-ion cells. They are very sensitive to charging conditions and may explode or burn
if mishandled.
•Do not replace the battery yourself. The battery is only manufacturer replaceable.
•Do not charge the instrument underground (mining) or in other hazardous locations.
•Always charge lithium batteries on a fire-proof surface.
•Do not charge the instrument near flammable materials such as boxes, paper and furniture.
•Immediately discontinue use of the instrument, while using, charging, or storing the instrument, if the
instrument emits an unusual smell, feels hot, changes colour, changes shape, swells, or appears
abnormal in any other way. Contact your sales location or SVANTEK if any of these problems are
observed.
•Use caution to prevent puncturing or rupture of the instrument and cell within. Do not penetrate the
instrument with nails, strike the instrument with a hammer, step on the instrument, or otherwise subject
it to strong impacts or shocks.
•Do not place the instrument on or near fires, stoves, or other high-temperature locations. Do not use

1 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 hours2of 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 SvanPC++.
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: “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 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.

1.1 SOUND PRESSURE
The human ear responds to audible sound pressure levels in the range from 20 μPa (hearing threshold) to
20 Pa (pain threshold), resulting in the enormous scale 1:1,000,000. Since using such a large arithmetic scale
is not practical, a logarithmic scale in decibels (dB) was introduced which is also in agreement with
physiological and psychological hearing sensations. Therefore, it is common that sound pressure is measured
in decibels. Below there is sample information about expected sound levels for different sources.

1.2 DOSIMETRY
Noise is definitely a serious hazard in many workplaces. In case exposure to noise from machinery processes
and equipment is not correctly eliminated or controlled, it may cause permanent hearing loss in workers. The,
so called, inner ear is very fragile part of our hearing sense, which with current knowledge in medicine, cannot
be truly repaired. Therefore, it is of great importance to protect our senses from excessive noise. Exposure to
high levels of noise may also create physical and psychological stress, reduce productivity and interfere with
normal communications. This may lead to accidents and injuries by making it difficult to hear moving
equipment, other workers, and warning signals. Undoubtedly hearing loss has a very significant impact on the
quality of life for many workers and their families.
Therefore, measuring noise exposure in the workplace is fundamental part of all good hearing conservation
and noise reduction programs. The aim of taking a measurement with a noise dosimeter is to evaluate the
average exposure of employees to noise during a normal shift. Wherever the worker goes the noise dosimeter
goes too so that it captures all of the harmful noise during the typical day.
The dosimeter may be worn for the complete shift if the work pattern is so variable that it is difficult to predict
exactly what will occur or it may be worn for a shorter but representative period and then the full day’s dose
extrapolated from that sample.
1.3 STANDARDS
The effects of high sound exposure on hearing have been studied for many years. As far back in 1954 AIHA
(American Industrial Hygiene Association) –Rosenwinkel & Stewart –described a “new device which
integrates sound energy over finite time periods.”In 1956 –von Witternand & von Gierke obtained a patent for
a noise exposure meter for “indicating the total time that noise exceeded a certain predetermined level”.Since

15
SV 104BIS User Manual
then, measurements could be conducted over long periods of time and the instrument was worn by personnel
under normal work conditions.
Finally, organizations developed standards to regulate personal noise exposure. International standards are
specified by health and safety regulations such as the European Union Parliament and Council Directive
2003/10/EC of February 6, 2003 on minimum health and safety requirements regarding the exposure of
workers to the risks arising from physical agents (noise) or International Electrotechnical Commission
IEC 61252 guidelines. The EU directive links to the ISO 9612:2009 Acoustics –Determination of occupational
noise exposure –Engineering method.
In the United States, the Occupational Safety and Health Administration (OSHA) 29 Code of Federal
Regulations (CFR) 1910 General Industry Regulations: Standard No. 1910.95 Occupational noise exposure,
the Mine Safety and Health Administration (MSHA), and the American Conference of Governmental Industrial
Hygienists (ACGIH) have created slightly different regulations and limitations on tolerable noise exposure.
Noise requirements are to ensure that the hazards associated with the exposure of workers to noise are
eliminated or properly controlled.

Additionally, at present dosimeters should meet relevant accuracy and performance requirements defined by:
- IEC 61252 Personal Sound Exposure Meters
- ANSI S1.25 Personal Noise Dosimeters
1.4 APPLICATIONS
The SV 104BIS noise dosimeter is extremely well suited to ISO, OSHA, ACGIH, MSHA, NIOSH, CFR 1910.95,
HSE L108 workplace noise measurements in noise exposure assessments. NIHL: Noise Induced Hearing
Loss remains noticeably significant occupational disease It is notably severe in the mining, construction,
oil &gas industry but also in a wide variety of manufacturing sectors and other commercial operations. The
dosimeter comes with pre-defined setups that suit different measurement requirements and offer versatile
possibilities to be specifically configured by the user for special requirements if needed:
- measurement and control of the industrial noise
- work site assessments
- sites/plants/facilities survey monitoring systems
- hearing conservation compliance, noise induced hearing loss (NIHL)
- transportation noise studies
- personal noise verifications
- peak dosimeter for example in military applications.
One of the most desirable SV 104BIS feature is the unique data logging function that stores significant number
of noise parameters at regular intervals and superimposed random vibration shock or audio events during
a measurement run.

16
SV 104BIS User Manual
Due to the unattended nature of noise dosimetry, it is important for workers to be fully engaged with the risk
assessment process. Motion sensing (No Motion Time) is particularly useful in cases of cheating to tamper
with the instrument or try to impact on the results, by for example instrument being taken off for the majority of
the time.
The addition of Bluetooth®wireless connectivity and the supporting mobile devices Assistant application
enables remote control and monitoring of the instrument’s status such as battery usage, memory capacity and
measurement progress without having to disturb the worker.
Noise profiled results can be easily transferred to the Supervisor or SvanPC++ software packages.
The noisiest times can be immediately seen in the graphical report and actions directed to the appropriate
area. This makes checking for different regulatory bodies’ compliance and ensuring if hearing conservation
programs are needed definitely easier than ever before. SV 104BIS answers all the important questions such
as WHEN and HOW did the noise exposure appear? The data logging measurements can be started
immediately, or they can be pre-programmed in advance so that measurement run can begin and end
automatically at a pre-set start and end time without the need for any onsite supervision.
Additionally, SV 104BIS allows for custom voice note comments to be added before or after
the measurement run, and therefore this is the ideal instrument for the professional occupational hygienist to
use for all noise exposure studies.
1.5 MEASUREMENT PROCEDURES
Preferably, when taking measurements, the noise dosimeter should be attached to the employee at the start
of a shift and collected at the end of the whole shift. In case a shorter period is sampled then care should be
taken to ensure that the result is representative of the full shift exposure. Shorter sampled periods require that
the sampler has a deep and full understanding of the expected working tasks during the shift and the duration
cycles of those tasks.
Before performing any noise measurements, ensure that employees selected for evaluation are operating
equipment or performing tasks under normal (representative) conditions, and emphasise the importance of
continuing to work in their usual manner (wearing the dosimeter should not interfere with normal duties).
Explain the purpose and procedures of sampling to the employee who will be wearing the dosimeter and the
importance of not touching, tapping or interfering with the microphone. Instruct the employee not to remove
the dosimeter unless absolutely necessary.
The general procedure for taking measurements could be as follows:
1. Check that the indicated instrument battery life is at least twice the time required for
the measuring period.
2. Check the instrument setup mode is appropriate and change if necessary.
3. Check the calibration of the instrument and adjust the settings if required.
4. Secure the instrument onto the shoulder of the employee selected for sampling. Refer to
the chapter with specific requirements regarding orientation of the microphone.
5. Start the recording session manually if it is not programmed for an automatic timed start.
6. At the end of the measurement period, stop the recording session, and remove the dosimeter
from the employee.
7. Recheck the dosimeter’s calibration. If the instrument is not within the calibration limits then the
results are invalid (usually if a discrepancy is found between two successive checks of more
than ± 0.5dB in the reference level, then the results of the measurements taken between the
two checks should be considered invalid and the cause investigated, and the measurement
repeated).
8. Follow your organisation’s specific procedure for personal noise exposure recordings analysis
9. Ensure the report is submitted to the appropriate person.
10. Distribute copies of noise exposure recordings to test participants, explain the results and
ensure that their hearing protection adequately protects against the recorded noise exposure
levels.
