SPECIAL PRECAUTIONS WHEN USING AND CHARGING LITHIUM BATTERIES
SV 104A 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 battery yourself. The battery is only manufacturer replaceable.
• Do not charge the instrument underground (mining) or in other hazardous locations.
• Always charge lithium batteries in/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
or store the battery inside cars in hot weather. Do not place the instrument in direct sunlight or use
or store the instrument near a source of heat. Doing so may cause the battery contained inside
to generate heat, explode, or ignite. Using the instrument in this manner may also result in a loss of
performance and a shortened life expectancy.
• Do not place the instrument in microwave ovens, high-pressure containers, or on induction cookware.
• Although the instrument is IP65 protected do not expose it extensively to water conditions which could
cause the contained battery to get wet.
• The temperature range over which the instrument can be charged is 0°C to 40°C. Charging
the instrument at temperatures outside of this range may cause the battery to become hot or to break.
Charging the instrument outside of this temperature range may also harm the performance of the
battery or reduce the battery’s expectancy.
Assure that all of these precautions are observed before leaving the instrument charging unattended.
• The temperature range over which the battery can be stored is -20°C to +50°C and the temperature
range over which the battery can be discharged is -10°C to +50°C. Use of the battery outside of this
temperature range may damage the performance of the battery or may reduce its life expectancy.
• If you notice a performance decrease of greater than 20% in instrument, the battery is at the end of its
life cycle. Do not continue to use, and ensure the battery is disposed of properly. Contact your sales
location or SVANTEK.

1 INTRODUCTION
Now, the SV 104A instrument is even more revolutionary 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 ST 104A)
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 104A instrument can simultaneously
measure the dosimeter results and perform real time 1/1 Octave & 1/3 Octave analyses including the
calculations of the statistical levels.
An inbuilt tri-axial accelerometer for vibration shock detection firmly places SV 104A 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 48
hours
2
of continuous operation. Ultra-low battery self-discharge is about 1% per year. The powering and
charging of the instrument from the USB interface is provided which also enables easy data exchange
connection between the SV 104A and a PC without the requirement of a special docking station. Alternatively,
powering and charging of the instrument is possible with one of SB 104A-X series docking station with
the USB interface which also enables easy data exchange with PC.
The instrument works with Svantek’s specialist health and safety software packages – Supervisor,
mobile Assistant, and also with the full analysis package SVAN PC++.
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 the SV 104A, 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 1:10,000,000. 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 levels.”
Since 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.
SV 104A USER'S MANUAL_______________________________________________________

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
- ANSI S1.25
1.4 Applications
The SV 104A 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 104A 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 run.
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. The SV 104A 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, the SV 104A 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.

3.3 The windshield
During use, it is strongly recommended that the SV 104A is fitted with the supplied SA 122A windshield.
To calibrate the dosimeter, it is necessary to remove the windshield to gain access to the microphone. It is not
necessary to remove the windshield to record the voice note comments.
The SV 104A uses anti-clockwise thread technique to fit tightly onto the microphone housing. To remove
the windshield, unscrew the windshield holding the lower half of the foam and lift the windshield off the
microphone housing. Once the SV 104A has been calibrated, refit the windshield by carefully screw it
clockwise over the microphone again.

3.8 Three instruments in one – ACOUSTIC PROFILE concept
SV 104A is able to monitor and log noise by enabling up to three different parameter configuration
settings, also referred to as “ACOUSTIC PROFILE”. One can set profile no 1 to run measurements using the
OSHA HC (Occupational Safety and Health Administration - Hearing Conversation) parameters and at the
same time set profile no 2 to monitor the noise with the OSHA PEL (Occupational Safety and Health
Administration – Permissible Exposure Level) parameters while profile no 3 is set to ACGIH parameters. This
is the true triple instrument in one.
3.9 The VIEW mode presentation concept
Such an advanced noise dosimeter as the SV 104A offers a large amount of parameters for the operator
to inspect. Therefore, all information is divided in a neatly organized manner as VIEW modes for each
PROFILE.
The VIEW mode is a way in which the measurement parameters are presented to the operator. In other
words, when you change the VIEW mode, specific measurement parameters and status information will be
presented in different manner as distinct screen content.
SV 104A features the following VIEW modes, where most of them can be individually disabled:
▪ Running instantaneous SPL view mode ( 3.9.1) - can be disabled with PC software
▪ Primary “one-result” parameters view mode ( 3.9.2) - cannot be disabled
▪ Results list view mode ( 3.9.3) - can be disabled with PC software
▪ Octave analysis spectrum LEQ view mode ( 3.9.4) - can be disabled with PC software
▪ Octave analysis spectrum MAX view mode ( 3.9.4) - can be disabled with PC software
▪ 1/3 Octave analysis spectrum LEQ view mode ( 3.9.5) - can be disabled with PC software
▪ 1/3 Octave analysis spectrum MAX view mode ( 3.9.5) - can be disabled with PC software
▪ Instrument Status view mode ( 3.9.6) - can be disabled with PC software
3.9.1 Running SPL view mode
Running SPL presentation mode is used when measurement run is not actually running, that is when
the instrument is in standby mode before or after a measurement. In this mode the current SPL result is
calculated and displayed, but not stored in the instrument's memory. The purpose of this information is to give
the user a first indication of the sound levels about to be measured. This can be useful for some
measurements. The instrument behaves as a simple general purpose sound pressure level meter in this view
mode.

3.9.2 Primary “ONE-RESULT” view mode
The one result mode is always available in all measurement modes, and cannot be disabled. In one
result mode, any measurement result, selected via <SCROLL> , may be presented. The user may change
the actual profile view by pressing <PROFILE> key. This view mode is useful if in low vision conditions
or is suitable for operators with some visual impairment.
Figure 3-11 Primary ONE RESULT view mode screen
3.9.3 RESULTS LIST view mode
To get information about a number of results at one time it is handy to switch to the “results list” view
mode. Up to three parameters at a time are accessible for the operator.
Figure 3-12 RESULTS LIST view mode screens
3.9.4 OCTAVE analysis spectrum view mode
The instrument operates as a real time 1/1 octave band analyser (RTA). In addition and if enabled, 1/1
octave analysis is performed in parallel with the dosimeter operations. All 1/1-octave digital pass-band filters
(with 9 centre frequencies from 8 kHz down to 31.5 Hz; in base two system) are working in real-time with the
broadband frequency weighting filters (Z, A or C) and the linear LEQ (LEQ) detector. This enables the user to
pre-weight a spectrum with one of the selected broadband frequency curves if required for a particular
application such as the provision of hearing protectors in the control of high workplace noise levels.

Note: The three overall TOTAL LEQ results are measured with the weighting filters (A, C, Z)
without taking into account the settings of the level meters for profiles. The spectra are always linearly
averaged. Thus, the TOTAL values from 1/1 octave band analysis can be different from those obtained for the
profiles (if the LEQ Integration was set as Exponential).
The results of 1/1 Octave analysis (so-called spectrum) can be examined by the user on a display
in Spectrum VIEW presentation mode. 1/1 Octave spectra for all 9 centre frequencies of pass-band filters
together with the 3 TOTAL overall values measured with the user selected frequency weighting filters
are presented in the Spectrum mode if enabled in configuration setup. Spectrum cursor can be moved left and
right with <SCROLL> , <PROFILE> keys respectively.
With the use of Supervisor software, the user can select which spectrum (LEQ, MAX or both) will be
available for view (see chapter 6.5.5).

3.9.5 THIRD OCTAVE analysis spectrum view mode
The instrument can also operate as a real time 1/3 octave band analyser (RTA). In addition and
if enabled, 1/3 octave analysis is performed in parallel with the dosimeter operations. All 1/3-octave digital
pass-band filters (with 28 centre frequencies from 10 kHz down to 20 Hz; in base two system) are working in
real-time with the broadband frequency weighting filters (Z, A or C) and the linear LEQ (LEQ) detector. This
enables the user to pre-weight a spectrum with one of the selected broadband frequency curves if required for
a particular application such as the provision of hearing protectors in the control of high workplace noise levels.
Note: The three overall TOTAL LEQ results are measured with the weighting filters (A, C, Z)

4 RUNNING AND OPERATING BASIC PROCEDURES
4.1 USB Charging
The battery inside SV 104A uses lithium-ion technology which requires special consideration and handling
techniques due to the extremely high energy density (see “SPECIAL PRECAUTIONS WHEN USING AND
CHARGING LITHIUM BATTERIES” clause on page 4).
Note that SV 104A dosimeter is equipped with an internal charger, so that the fixed internal batteries
can be charged directly from computer USB port or optionally provided charger (SA 54: universal micro-USB
charger).
Ensure the SV 104A is fully charged prior to use by connecting it to a USB port or to USB charger.
Ensure the power supply is connected and the supply is switched on. The SV 104A will automatically turn on
the display during charging and present how much charge is within the instrument. The SV 104A will display
‘Fully charged’ once charging is complete. This should take approximately 2 hours from a fully discharged
state. A charging time of about 30 minutes will be sufficient to perform greater than 8 hours of measurement.
A fully charged instrument holds enough charge to run for approximately 48 hours.
Note that once disconnected from USB power supply, the dosimeter will automatically switch off.
If returned to the USB connection or put again onto the docking station the dosimeter keeps trickle charging
regardless of whether or not it is fully charged. This keeps the battery performance in steady condition. If the
battery is fully discharged prior to being placed on a charger, the SV 104A trickle charges for a short time prior
to the fast charge cycle, this prevents damage to the batteries.
The number of hours you have used your dosimeter from your last charge will impact total charge time.
For example, if the battery clock indicator displays 40 hours remaining on the battery and you wish to charge
the battery, the approximate charging time is 1 hour.
Note: To charge a fully discharged battery, it would take approximately 2 to 2.5 hours or about
7-7.5 hours when using low power USB interface.
Note: To charge multiple dosimeters at the same time via the USB port, ensure your
computer or possibly the powered USB hub such as the SA 156 or switch is capable in terms of providing
enough current performance. Standard hub or switches without external power supply are not capable to
charge multiple SV 104A dosimeters due to insufficient current supply.
Current estimation: Assume the current consumption on 0.5A level, and calculate required power supply
requirement (N x 0.5A).
Power wattage estimation: With nominal voltage of 5V per USB, the power supply wattage should be 2.5W
per dosimeter (Nx2.5W).
For example, 5 dosimeters charged at once require: 2.5A/12.5W USB power supply
For example, 3 dosimeters charged at once require: 1.5A/7.5W USB power supply
For example, 1 dosimeter charged alone requires: 0.5A/2.5W USB power supply
Note: Use only high quality USB cables, such as SC 156. Many poor-quality cables do not
ensure low resistance of the cable, thus disabling proper charging of the internal cells.
SV 104A USER'S MANUAL_______________________________________________________

4.1 DOCK STATION Charging
The battery inside SV 104A uses lithium-ion technology which requires special consideration and handling
techniques due to the extremely high energy density (see “SPECIAL PRECAUTIONS WHEN USING AND
CHARGING LITHIUM BATTERIES” clause on page 4).
Ensure the SV 104A is fully charged prior to use by placing it onto the docking station charger.
Ensure the power supply is connected and the supply is switched on. SV 104A will automatically turn on the
display during charging and present how much charge is within the instrument. The SV 104A will display ‘Fully
charged’ once charging is complete. This should take approximately 4 hours from a fully discharged state. A
charging time of about 1 hour will be sufficient to perform greater than 10 hours of measurement. A fully
charged instrument holds enough charge to run for approximately 48 hours.
Note that once disconnected from docking station, the dosimeter will automatically switch off. If put again
onto the docking station the internal battery is float charged. This keeps the battery performance in steady
condition. If the battery is fully discharged prior to being placed on a charger, it trickle charges for a maximum
1h time prior to the fast charge cycle, this prevents damage to the batteries.
The number of hours you have used your dosimeter from your last charge will impact your total charge
time. For example, if the battery clock indicator displays 10 hours remaining on the battery and you wish to
charge the battery, the approximate charging time is 3 hours.

Table 4-1 Charger instrument LED status description
Figure 4-1 5-bay docking station (SB 104A-5)
Note: To charge a fully discharged battery, it would take approximately 4 hours.
Note: To charge multiple dosimeters at the same time via the docking station, ensure your
12V AC/DC power supply such as the SA 33 is capable in terms of providing enough current performance.
Current estimation: Assume the current consumption on 0.24A level, and calculate required minimum power
supply current (5 x 0.24A = 1.2A).
Power wattage estimation: With nominal voltage of 12V the power supply wattage should be minimum 2.88W
per dosimeter (5 x 2.88W = 14.4W).

4.2 Before you turn the instrument on
There are only a few things to remember:
• Make sure the microphone is properly fastened onto mounting head before turning on the
instrument.
• When in use for a measurement run, always use the SA 122A windshield provided.
4.3 Turning on/off
TURNING ON: To switch the power on the operator should hold the <ENTER> key for a couple
of seconds. The instrument switches on and goes the self-test routine (during this time the manufacturer's
logo, the name of the instrument and firmware version is displayed).
Then the SV 104A will run through a short start-up sequence, showing the current configuration setup
loaded along with the names of all of three profiles, followed by battery state screen. After this, the instrument
will enter the stopped (ready to measure) mode and enter the running instantaneous SPL mode if enabled.
Note: Warm up time - After power on, the instrument should be warmed up for at least
60 seconds before starting measurement.
Note: If you leave the instrument in stopped (ready to measure) mode, the display will be
switched off after 30 seconds, and the unit will turn off after approximately 5 minutes of no keypad activity
to save the batteries.
Note: SV 104A will show a warning screen if the battery capacity is below 2 hours of
potential measurement time.
TURNING OFF: To shut down the unit the operator should hold the <ENTER> key for a couple
of seconds during which a countdown (“Shutting down” 3… 2… 1… ) is displayed. Thus, the SV 104A gives
you time to decide if you really want to turn off the instrument. If you release the key too early, the SV 104A
returns to the last presented VIEW mode.
If enabled in the configuration setup there may be presented an additional, double-check, warning
screen. This is for the operator to be aware and convinced the unit is really to be turned off. See figure below:
Figure 4-2 Power-off warning screen
Note: SV 104A will automatically shut down after 5 minutes in stopped mode.
Note: If auto-run (timer) mode is active, SV 104A will automatically stop the measurement

4.4 Battery check
Observe the battery icon in the instrument’s icon status bar or press the <ENTER> key until
the Instrument Status view mode is presented and check the battery state. If it is too low, charge the batteries
(chapter 4.1).
Figure 4-3 Instrument Status - Battery state
Battery status screen is moved down and up with <SCROLL> , <PROFILE> keys.
Press <ENTER> to change to the next VIEW mode.
Note: Battery state of charge calculation is based on internal charge counter and should be
considered only as an overall, not very precise estimation. Therefore the time left could be noticeably
different. Although the newest technology cells are used the slight degradation over time is inevitable thus
aging requires occasionally factory based (or authorised service centre) replacement of the rechargeable
battery cells.,
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 micro USB port or docking
station. The procedure is recommended before first use. Repeat this procedure every few months of use
to maintain more accurate current battery condition indication.

4.7 CALIBRATION
The SV 104A dosimeter is offered with the dedicated ST 104A MEMS microphone with ½” housing.
It makes the calibration very easy by direct usage of commonly available acoustic calibrators with a ½” cavity.
The instrument is factory calibrated with the supplied microphone for the standard environmental conditions.
Because the microphone sensitivity is a function of the temperature, ambient pressure and humidity, the
absolute calibration of the measurement channel should be performed locally. The instrument performs the
acoustic calibration automatically, when the calibrator is placed over the microphone (first remove the
windshield). The calibrator level is automatically detected and the calibration procedure is started.
The user simply has to press <ENTER> key to confirm the calibration results. Calibration is only
allowed in the stopped mode. A sound measurement cannot be in progress while the calibration is being
performed.
Note: It is advised to perform an acoustic calibration of the instrument each time before and
after the measurement run. A single calibration at the start of each day of use is usually sufficient for most
regulations.
Note: The calibration factor is always added to the results in the Dosimeter or 1/1 Octave or
1/3 Octave analyses modes.
Note: The manufacturer’s recommended factory calibration interval is every 12 months for
this instrument to be confident in its continuing accuracy and compliance with the international specifications.
Please contact your local SVANTEK distributor for further details.
To calibrate the instrument manually the user has to enter the Calibration menu.
SV 104A USER'S MANUAL_______________________________________________________
35
1. Adjust the actual calibration level of the calibrator to be used with the <SCROLL>
and <PROFILE> keys
Figure 4-8 Calibration menu
2. Attach the acoustic calibrator, SV 30A, SV 31, SV 34, B&K 4231 (or equivalent 114 dB / 1000 Hz)
carefully yet tightly over the microphone of the instrument. The presence of the calibrator will be
detected automatically
Note: It is also possible to use an electro-mechanical pistonphone, which generates the signal
(ca 124 dB) or different type of acoustic calibrator dedicated for ½” microphones with an alternative output
level such as 94 dB at 1 kHz. In any case, before starting the calibration measurement, the user has to
set the level of the signal generated by the given calibrator (Level position), which is stated in the
calibration certificate of the unit (the default expected value of the Calibration Level set by the manufacturer
of SV 104A is equal to 114 dB).
3. Switch on the calibrator and wait ca 30 seconds for the tone to stabilise before starting the calibration
measurement
4. Start the calibration measurement by pressing the <ENTER> key
5. The calibration measurement time is set to 1 second with 3 seconds’ delay and stops until the same
result is obtained 3 consecutive times. It is possible to stop the calibration measurement by pressing
two keys at the same time <PROFILE> and <ENTER>.
Figure 4-9 Calibration - initial delay screen
6. Delay before starting calibration measurement is counted down on the display. After the measurement,
its result is presented on the display.
Figure 4-10 Calibration in progress screen
Note: To quit the calibration procedure without saving the calibration factor press <PROFILE>
and <ENTER>.
7. It is recommended to repeat the calibration measurement a few times. The obtained results should be
almost the same (with ±0.1 dB difference). The reasons for the unstable results are as follows:
SV 104A USER'S MANUAL_______________________________________________________
36
• the calibrator is not properly attached to the instrument
• there are external acoustic disturbances such as high noise levels close by
• the calibrator or the measurement channel (for example the microphone) is damaged
Note: During the calibration measurement, the external disturbances (acoustic noise
or vibrations) should not exceed a value of 100 dB (when using a calibrator that generates a level
of 114 dB).
8. Press the <ENTER> key in order to accept the measurement result.
Figure 4-11 Calibration confirmation screen
Note: If a calibration factor does not meet tolerance criteria ±2 dB, you still can manually
accept the microphone, but the results could possibly be affected - see Figure 4-12.
Figure 4-12 Calibration - microphone not in tolerance screen
9. Post calibration. If enabled, the post processing is performed automatically under acceptance
of calibration measurement.
Note: If it is required to perform so called post-calibration of the instrument. In case the Post
Calibration is pre-programmed within configuration setup the SV 104A automatically adds the results to
the previously saved files.

6.7 Working with sessions and reporting
One of the main advantages of the Supervisor is its incredibly simple but professional and user
customizable report creation. Once you get familiar with the power of document design you will love it and
probably never come back to the old-fashioned way of reporting.
When the measurement data is downloaded via the download feature, the data is stored and viewable
via the local file “Data Browser” window. Further work with data downloaded from dosimeter is based
on, so called, SESSIONS – the most advanced charting, tables, and reporting capability in its class.
Each SESSION is highly configurable and the template of a document once created (Figure 6-25) can
be saved for future use with other measurement data. That gives the operator quick solutions at the
fingertip. The information is divided into panels and viewable in customizable graphs and/or with
selected measurement data/parameters.

7 SV 104A MAINTENANCE
7.1 General recommendations for use
7. Use only high quality USB cables, such as SC 156. Many poor-quality cables do not ensure low
resistance of the cable, thus disabling proper charging of the internal cells
8. It is not recommended to leave the instrument in direct sunlight conditions for prolonged periods
of time. Extended exposure such as behind the car window may affect the performance.
9. To improve accuracy of remaining battery life indicator, run the dosimeter until it is fully
discharged; then proceed with a full charge via the micro USB port. The procedure
is recommended before first use. Repeat this procedure every few months of use to maintain
more accurate current battery condition indication.
7.2 Cleaning
Few things to remember:
• Every time the SV 104A gets too dirty, clean the surface of the dosimeter with damp soft cloth.
• Pay special attention that the provided SA 122A windshield is clean because dirtiness can affect
the measurements. Take off the windshield, shake off any dirt, and clean it with damp cloth.
If necessary change the windshield to new one. The foam windshield is considered a
consumable item and will need replacing if it becomes lost or its condition deteriorates too much.
Packs of 3 replacement windshields are available under the part number SA 122A_3.
• Pay special attention that the ST 104A microphone front part is clean because dirtiness can
affect the measurements. Avoid the small inlet hole getting too dirty. Clean carefully with a dry
and soft non-fraying cloth.
7.3 In situ calibration
It is advised to perform an acoustic calibration of the instrument each time before and after
the measurement run. A single calibration at the start of each day of use is usually sufficient for most
regulations. See chapter 4.7 for calibration details, please.
7.4 Periodic testing
The manufacturer’s recommended factory calibration interval is every 12 months for SV 104A
to be confident in its continuing accuracy and compliance with the international specifications.
Note: Please contact your local SVANTEK distributor for further details on traceable
recalibrations that are recommended by most regulatory authorities.
SV 104A USER'S MANUAL_______________________________________________________
76
7.5 Changing the microphone and windshield
To change the microphone, take off the windshield first (see chapter 3.3). Now, you need to unfasten
the microphone from the mounting head. Unscrew the microphone in a counter-clockwise direction.
To attach a new microphone, screw the microphone on clockwise until it fits tightly. It is critical to make
sure the sensor is tightly fitted. Use the NM104I1Z wrench but be gently and be aware not to break or strip
the thread.
Note: Note, when the microphone is changed, the new microphone serial number is
automatically stored into the SV 104A internal memory.
In case the windshield is destroyed/lost by any accident, or it gets too dirty to afford the microphone the
best protection then SVANTEK offers SA 122A_3 three pcs per pack (windscreens for SV 104A dosimeter).
7.6 Firmware update
SVANTEK is committed to continuous innovation path of development, and as such reserves the right
to provide firmware enhancements based on user’s feedback.
To update the instrument firmware:
• Unpack the provided firmware package (provided as a suitable compressed file).
• Make sure the unit is turned off.
• Hold down the <PROFILE> key and press the <ENTER>key to turn on the unit. This
ensures the unit will switch on and enter the special reprogramming BOOTLOADER mode.
Figure 7-1 Bootloader update mode view
• Then connect the USB cable. The <USB> text will now appear on the instrument display.
• Run the start.bat file.
• Successful firmware update will be indicated by relevant message.
• Turn off the unit.
Note: With use of Supervisor software it is very easy to check if there are
any new firmware releases available for download (see Figure 6-3 commands).
SV 104A USER'S MANUAL_______________________________________________________
77
7.7 Storing the instrument
• To preserve the life of the internal batteries, it is recommended that the SV 104A instrument
is turned off when it is stored, and battery charge at half the capacity.
• Do not store the instrument permanently connected to the USB port or put on docking station.
It shortens battery lifecycle.
• It is recommended to turn off the Bluetooth® interface in applied settings;
• When the SV 104A is turned off, it still draws a small amount of battery power. Therefore,
it is recommended to 50% charge of the cell every few months if it is not going to be used
regularly.
7.8 Transportation and carrying
For transportation or storage purpose, always use the packaging provided by the manufacturer.
In a potentially dirty industrial environment it is advisable to use the carrying case provided by the manufacturer
such as the SA 73 (see chapter 2.3), which ensures excellent mechanical and environmental protection and
long term storage conditions.
Note: For Air-transport Bluetooth® interface should be turned off. Make
sure that correct settings file is applied.
7.9 Troubleshooting
1. Upon connection to the USB port, if automatic charging is not started: check the USB cable and power
supply ratings of the source.
2. If the incorrect time or date is displayed when turning on the instrument connect the device to the
computer and use Supervisor software to set the time and date (see) ensuring PC clock is set
correctly
3. In case the instrument is not able to turn on ensure the unit is charged by connecting to USB
or recommended charger. This ensures the battery is not exhausted. Then proceed with hardware
reset (chapter 0)
4. In case your dosimeter does not respond proceed with turn-off/turn-on procedure (chapter4.3),
and hardware reset of the instrument (chapter 0).
5. In case the measurement of the sound level is frozen or set to a fixed value proceed with turn-off/turn-
on procedure (chapter 4.3), then with hardware reset of the instrument (chapter 0).
6. In case the reset does not help proceed to chapter 9.
