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 authorised 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 signalled 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 kit;
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.

1 INTRODUCTION
SV 258 PRO is an outdoor monitoring system based on the
SVAN 958A class 1 vibration and sound four-channel level
meter dedicated for ground and building vibration
applications. The portable and battery powered station can
be used for a variety of monitoring applications including
construction site monitoring, tunnelling and blasting.
The IP 67 rated case contains a lead-acid battery which
operating time can be easily extended by connecting an
external battery or a solar panel. The intelligent charging unit
allows to use a solar panel without expensive controllers and
heavy batteries.
The station case is fitted with very robust, waterproof
connectors (military standard) and comes with an IP 65
external power supply. The system uses a low-noise,
hermetically sealed tri-axial piezoelectric accelerometer
enabling the outdoor use without additional enclosures. The
accelerometers' signal ground is insulated from themounting
surface and outer case to prevent ground loops. All
accessories fit conveniently into a second carrying case.
The monitoring station uses the mobile modem for the remote communication with the Internet. SvanNET,
a relay server, supports the connection between PC and the station allowing the usage of all types of SIM
cards, regardless if they have public or private IP. The use of SvanNET gives access to the status of the
monitoring station also via mobile phone or tablet.
SV 258 PRO may be delivered with two firmware versions of SVAN 958A.
The basic firmware of SVAN 958A is dedicated for general four channel measurements and the user may
configure all channels independently. This firmware is supplied as a standard with SVAN 958A and can be
used for monitoring of vibration and sound levels when SVAN 958A is a part of the monitoring station
SC 258 PRO. This basic firmware has a so-called Ground Vibration option that allows simplified functions
for construction site monitoring.
The special firmware (SVAN 958AG) is dedicated for building vibration measurements and uses methods
based on Peak Particle Velocity and Dominant Frequency. Measurements of human vibration in buildings
are also possible as the instrument allows simultaneous measurement of velocity and acceleration of
vibrations with two independent steps of recording. In addition, it is possible to enrich the measurement with
Class 1 sound results.
Note: This manual describes SV 258 PRO comprising SVAN 958A with the basic firmware
(rev. 4.10.5).

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 the SB 270 power supply or an optional
solar panel or an external battery).
Another key task of the controller is the integration of the entire system –examining the communication,
state and condition of every module of the system and the immediate indication of all problems on the
control panel by means of several LEDs or remotely using the mobile 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 allows you to reset the controller settings. To do this, press
and hold the TEST key for more than 20 seconds until the corresponding LED lights up. Release the key
and the controller will be reset.
The mini USBconnector on thefront panel of the controller is intended for updating thecontroller firmware.
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
interface of SVAN 958A (USB socket).
Note: Communication of the controller or SVAN 958Awith a PCrequires installation of the USB
drivers on your PC. USB drivers for Svantek devices are available on
http://svantek.com/support-drivers-software.html
Note: Make sure SvanPC ++ is Off before starting the update! If not, please Exit it before

2.2 OPTIONAL ACCESSORIES FOR SV 258 PRO
2.2.1 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 using 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 Appendix B to learn how to assemble and
disassemble the outdoor microphone kit.
Note: After assemblingthe 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 a test measurement each time the station is turned on.
2.2.2 Vibration Calibrator
The SV 111 vibration calibrator is designed for in-situ checks
according to ISO 8041-1:2017. In-situ checks are intended for
application in the field prior to and following a measurement or
series of measurements.
The SV 111 is suitable for calibration checks of various of vibration
transducer types at different frequencies from 16 Hz up to 640 Hz.
Depending on the selected frequency you may choose the level of
the calibration from 1 m/s2to 10 m/s2.
SV 111 has robust casing and built-in rechargeable battery.
To calibrate or check the measurement system with the SV 84
accelerometer the special SA 154 calibration adapter is needed.
This adapter is optional, not included in the monitoring station
standard set.
2.2.3 Sound Calibrator
The SV 36 1 Class Sound calibrator produces sound pressure of
declared levels - 94 or 114 dB at a frequency of 1 kHz.
This calibrator is equipped with the autorun function. It starts
generation of the declared sound pressure automatically after
insertion of the microphone into the calibrator hole.

2.2.4 External rechargeable battery
SB 272 is an external source of DC power for the monitoring
station. It includes a Lead-Acid rechargeable battery (33 Ah, 12 V)
and is dedicated for outdoor use because of its waterproof case.
The battery capacity enables up to three times longer operating
time of the monitoring station.
The SB 272 set includes the SB 273 indoor charger and a cable
for connection between SB 272 and the monitoring station.
SB 272 has the same connector for charging and for power supply and therefore cannot be used as a
power supply for the monitoring station and at the same time be charged (as the internal station battery
when it is charged from the solar panel or external power supply).
Note: SB 272 cannot be charged by the monitoring station SB 270 power supply!
Note: SB 272 is not restricted for air, surface and water transport. Classified as non-hazardous
material (IATA/ICAO Special Provision A67, DOT-CFR Title 49 parts 171-189, IMDG
amendment 27).
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 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.
The SB 271 solar panel does not require additional batteries or
external controllers.
The mounting system enables mounting of the SB 271 solar panel
above the monitoring case which provides a natural shade that
protects the station from overheating.
SB 271 is equipped with a military standard connector cable for
direct connection to the monitoring station.

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 powering the station and charging 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 loading 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: 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!
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 –mobile modem connection state,
•EXT I/O –reserved.
Colour of LEDs can be 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.
