IMPORTANT NOTES BEFORE USE
✓Only SVAN 958A and the controller can be disconnected and removed from the station case by the user.
All other disassembling work should be performed strictly by an authorized service team.
✓The producer does not recommend removing the controller without a sound reason. Double check that
the controller has a good fixation in the connector after reconnecting.
✓Do not remove the battery from the case! This operation must be done only by the authorized service.
✓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.
✓The correct connection of the accelerometer or microphone is not signaled by the controller therefore it is
recommended to perform a test measurement each time the station is turned on.
✓During station operation it is recommended to charge the internal and external batteries as often as
possible; this will extend battery life. It is necessary to charge the battery after any total discharge.
✓Monitoring station and/or SB 272 should not be stored for a long time with discharged batteries. Storing
with batteries in discharged condition may damage them.
✓If Monitoring station and/or SB 272 are planned to be stored for a long period of time, it is recommended
to charge their batteries to 100% capacity. Batteries should be charged at least once per 6 months.
✓If the storage period is longer than one year, a discharge/charge cycle must be performed. To do this,
leave the device turned on until the battery is completely discharged. Then charge the battery to 100%
capacity.
✓Monitoring station and SB 272 have their own chargers, which are incompatible: SB 270 is a waterproof
power supply for SV 258 PRO, whereas SB 273 is an indoor charger for SB 272.
✓If you use the SV 208A sound measurements set, before installing the station at the measurement site,
make sure that the protective caps on the four anti-bird spikes of the SA 277 outdoor microphone
protection kit are removed. It is recommended to use the protective caps during transportation, storage
and other operations with the instrument like, laboratory calibration, etc. to avoid personal injury.
✓The windscreen influences the free-field characteristics of the SA 277 outdoor microphone protection;
therefore, it is important to check its condition regularly. In the case of visible degradation of the foam
surface it must be replaced by the new one.
✓If you use desiccator (silica gel) inside the outdoor microphone protection, it should be regenerated after
some period of use, when it changes colour to light grey, by drying it for 3 hours in a temperature of 150°C.
Desiccator should be inspected at least every two weeks, and more often when used in conditions of high
air humidity.

integrates and controls all system modules and is
responsible for power distribution to all elements and
communication between the following elements of the
monitoring station:
•SVAN 958A instrument,
•3G modem
and optionally
•Light and sound alarm etc.

SV 258 PRO (AG) User Manual
12
A very important task of the controller is power distribution - it provides appropriate DC power to every element
of the system (managing external power sources such as a power supply SB 270 or an optional solar panel or
an external battery).
The next key task of the controller is integration of the whole system –examining the communication, state and
condition of every module of the system and the immediate indication of all problems on its control panel by
means of several LEDs or remotely using 3G Internet connection.
The controller also analyses the temperature condition inside the monitoring station case. If the internal
temperature is higher than 50oC, the controller will switch off internal battery charging. If the temperature further
increases over 65oC, the controller will switch off the monitoring station. The station will be also switched off if
the internal temperature falls below -30oC.
The TEST key in the SD 270A PRO controller enables the controller resetting. To do this, press and hold the
TEST key more than 20 seconds until the LED lights up. Release the key and reset of the controller will be
done.
A mini USB connector positioned on the front panel of the controller is designated to the controller firmware
upgrade.
Note: The mini USB connector on the controller panel doesn’t provide any measurement or setup
data exchange with the PC. Such data exchange is carried out via the USB Device 1.1 interface of
SVAN 958A (USB socket).
Note: Communication of the controller or SVAN 958A with a PC requires installation of the USB
drivers on your PC. USB drivers for Svantek devices are available on http://svantek.com/support-
drivers-software.html
Note: Before starting upgrading be sure that your SvanPC++ software is Off! If not, please Exit it
before starting any upgrading.
To upgrade the SD 270 PRO controller firmware, go through the next steps:
1. If you upgrade the firmware without removing the controller switch off SVAN 958A and wait until all

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
SvanPC++ 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 4.
SVAN 958A has two input sockets: 4-pins Lemo compatible socket
type ENB.0B.304 for Channels 1–3and 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.

2.2 OPTIONAL ACCESSORIES FOR SV 258 PRO
2.2.1 SV 208A –Sound measurement set
The SV 208A Sound measurements set includes: Microtech Gefell
Prepolarised condenser microphone (MK 255), microphone
preamplifier (SV 12L), outdoor microphone kit (SA 277), desiccator
(SA 270D), preamplifier cable (SC 277) and carrying case
(SA 250). The outdoor microphone kit protects the preamplifier and
microphone from weather conditions. The use of the outdoor kit
requires an extension cable between the monitoring station and the
microphone preamplifier (SC 258). SA 277 is made of lightweight
materials and is easy to install on a tripod.
The outdoor microphone kit has ¾” screw on its bottom which
enables the use of standard tripods or other user specific
mountings. Technical data such as direct and frequency
characteristics associated with the microphone are specified in the
SVAN 958A User Manual.
Optionally you may use desiccator –Silica gel. Desiccator absorbs
moisture normally contained in the air.
Note: Desiccator should be regenerated after some
period of use, when it changes colour to light grey, by
drying it for 3 hours in a temperature of 150°C. Desiccator
should be inspected at least every 2 weeks, and more
often when used in conditions of high air humidity.
Note: See also SA 277 Assembly Guide to learn how to
assemble and disassemble the microphone outdoor
protection.
Note: After assembling the SA 208A or after calibration
check that the windscreen foam is properly installed. It
should be shifted close to the anti-bird spikes. Otherwise
the SA 208A free-field characteristics will be different
from declared ones.
For absolute certainty, push the windscreen up to the
stop.
Note: Before installing the station at the measurement
site, make sure that the protective caps on the four
antibird spikes are removed.
It is recommended to use the protective caps during
transportation, storage and other operations with the
instrument like, laboratory calibration, etc. to avoid
personal injury.
Note: Correct connection of the microphone is not signalled by the controller therefore it is
recommended to perform test measurements each time the station is turned on.

material (IATA/ICAO Special Provision A67, DOT-CFRTitle 49 parts 171-189, IMDG amendment27).
Note: It is necessary to charge SB 272 after any total discharge, otherwise the battery may lose its
capacity.
Note: SB 272 should not be stored for a long time with a discharged battery. Storing SB 272 with a
discharged battery may damage it.
Note: If SB 272 is planned to be stored for a long period of time, it is recommended to charge its
battery to 100% capacity. The battery should be charged at least once per 6 months.
Note: If the storage period is longer than one year, a discharge/charge cycle must be performed. To
do this, completely discharge the battery and then charge it to 100% capacity.
2.2.5 SB 271 –Solar panel
The SB 271 solar panel (40 W, 17.5 V DC) extends the working
time of the monitoring station. The size and weight of the panel
enables easy transportation in the dedicated carrying bag.

3 OPERATING THE STATION
3.1 POWERING
The SV 258 PRO monitoring station can be powered from:
•internal rechargeable battery,
•mains power source (SB 270);
and optionally from:
•external rechargeable battery (SB 272),
•solar panel (SB 271).
When the power supply is connected, it starts to power the station and load the internal battery in parallel (as
a voltage source).
When the external rechargeable battery is connected to the station the station controller switches the powering
from the internal battery to the external one. As soon as the external battery is discharged the controller
switches powering back to the internal battery.
When the solar panel is connected to the station it starts to load the internal battery (as a current source). And
all the time the solar panel charges the internal battery, the station continues to be powered from the internal
battery.
The status of powering is indicated at the controller’s panel by a combination of DC, CHARGING, BAT 1 or
BAT 2 LEDs (see Table below).
Note: It is recommended that the batteries of SV 258 PRO and SB 272 are charged before going
on site.
Note: The monitoring station and the external battery have their own chargers, which are
incompatible: SB 270 is a waterproof power supply for SV 258 PRO, whereas SB 273 is an indoor
charger for SB 272.
Note: SVAN958A 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!
3.2 CONTROLLER INTERFACE
The controller interface consists of several LEDs, which indicate the state of the station elements or their
connection with the controller:
•DC –external power supply connection state (AC/DC converter),
•CHARGING –charging state of the internal battery,
•BAT 1 –internal battery state,
•BAT 2 –additional external battery state,
•SVAN –SVAN 958A connection state,
•3G –3G modem connection state,
•EXT I/O –reserved.
Colour of LEDs canbe red, orange or green. Colour of the SVAN and 3G LEDs reflect the communication state
with the corresponding unit. Colour of the DC, CHARGING, BAT 1 or BAT 2 LEDs depend on the state of the
power supply and charging of the internal battery.
The table below shows combinations of LED colours in the specific power supply conditions.

Colour of the SVAN LED is green when there is a connection between the controller and SVAN 958A. If there
is no connection the colour is red (for example, when SVAN 958A is switched off). When there is data
transmission between the controller and SVAN 958A the green LED will be blinking. During connection
initialization or powering down phase it is blinking orange.
Colour of the 3G LED is green when there is a connection with the modem.When there is data transmission to
or from the modem the green LED is blinking. During connection initialization or powering down phase it is
blinking orange.
3.3 MODES OF STATION OPERATION
3.3.1 Operational mode
In the operational mode, SVAN 958A, controller and 3G modem are switched on and communication between
all modules is functioning correctly.
Data transmission is signalized by the blinking lights of the SVAN and 3G LEDs on the controller panel.
In the operational mode, the following modules are powered continuously: SVAN 958A, controller, 3G modem,
tri-axial accelerometer and outdoor microphone (optionally). The power supply for these modules can be
switched off only by turning off the SVAN 958A instrument.
When the station case is open all LED diodes of the controller shine, informing about the station state. The
