SV 307 User Guide
1
The SV 307 is an integrated Noise Monitoring
Station which means that the sound level meter
has been integrated with a 3G modem and outdoor
enclosure. The waterproof power supply is also
provided for continuous operation in the field. Each
SV 307 has its factory calibration certificate and
36-months warranty card.
The key part of the class 1 kit is the new MEMS
microphone with a lifetime warranty.
What's inside?
The SV 307 is a new Noise Monitoring Station
dedicated for permanent noise monitoring.
The compact waterproof housing of the SV 307
integrates: a class 1 data logging sound level meter,
patented acoustic system check, GPS module and a
wireless 3G modem.
Wireless communication, external powering and
control of the SV 307 is managed by the SvanNET
cloud service. SvanNET is an on-line solution with
a responsive design that is available on various
devices such as smartphones, tablets and any
standard PC using a web browser.
All in One
The SV 307 is capable of logging sum-
mary results (SR) and spectral data
with interval steps down to 1 second.
Also time history results (TH) down
to 100 milliseconds.
Summary results (SR) include LEQ,
PEAK, MAX, MIN with Slow, Fast, Im-
pulse time constants simultaneously.
Additionally SV 307 stores two rolling
LEQ, ten LN statistics and GPS coordi-
nates. If enabled, the summary results
also contain weather data results
such as wind speed and direction or
rainfall.
TH results offer fast saving of PEAK,
MAX, MIN, LEQ and 2 RUNNING LEQs.
If used, the 1/1 or 1/3 octave spectral
results are recorded in both SR and TH
results simultaneously.
Fundamental issues of the environmental noise monitoring application are:
measured indicators, powering, remote system check, remote communi-
cation and alarms.

What do we measure?
Use of 2 logging steps
Environmental noise measurements often use longer term ISO 1996-1 indicators
such as Lday and Lnight for compliance reporting and short term LEQ for
monitoring and alarm notification, e.g. based on 5 min results. With two
separate logging steps the SV 307 is capable of providing the required results
for both requirements simultaneously.

Getting started It is strongly recommended to configure the remote communication before going
on site. Start by inserting the SIM card into the slot shown.
It is important to remove the PIN protection from the SIM card.
For protection against water ingress the SIM card slot is located under the bottom
cover of the SV 307. The bottom cover operates as a gasket therefore it is neces-
sary to carefully unscrew the 4 screws to remove it.
It is strongly recommended to configure the remote communication before going
SIM card
The SV 307 uses a dual layer housing that protects the instrument from harsh
weather conditions. In order to remove the external housing unscrew the single
protection screw and turn the housing gently counter clockwise until it releases
then pull apart to separate:

The SV 307 is programmed to automatically establish a remote connection with
the SvanNET server. It can take up to 5 minutes to connect. The most important
parameter for the connection is the Access Point Name (APN). The default setting
for the APN is “internet”. It is possible that your specific local internet provider
is using a different APN in which case the APN must be entered manually in the
SvanNET application.
Access Point Name
SvanNET Application
SvanNET Application is a simple software user interface used for the configura-
tion of the SV 307 to connect with the SvanNET service. To obtain the application
visit www.svantek.com support page. Simply install the application on your PC,
connect the SV 307 by the SC 316 USB cable and click “Connect to SvanNET".
Station Configuration
Successful connection to the SvanNET server is indicated by the cloud icon. Once
the SV 307 is connected to the basic SvanNET service it is possible to access and
adjust its settings manually as required. Simply click the Configuration button in
the SvanNET APP.

Noise limits are typically expressed in number of decibels per hour, day-time or
per night-time. In practise this means that different alarms and notifications to
different recipients are needed in the day-time or night-time or within a selected
time range.
Alarms
Threshold Alarms
As part of the Automatic File Download function SvanNET can analyse the down-
loaded data to send SMS or email alarms based on different time periods and noise
levels. If needed, more advanced alarm triggers, such as 1/3 octave spectrum or
predicted LEQ can be also used. The configuration of threshold alarms is accessible
from Automatic Download Alarms:
Status Alarms
One of the most important functions of SvanNET is to monitor the status of con-
nected monitoring stations. In the case of any error in powering, data storage, sys-
tem check or clock offset SvanNET can trigger an alarm email. The configuration
of Status alarms ins available in the Status tab in SvanNET Projects.
SvanNET Projects is an optional payable extension to the basic service offering
fully automated management of multi-point noise and vibration monitoring tasks.
Tools such as Automatic File Download, Regular Data Storage, Advanced Alarms,
Data Sharing and Reporting enable simple unattended monitoring. The function-
ality of SvanNET Projects allows grouping multiple monitoring stations so that
alarms and reports are defined for each project separately. The data files are also
grouped automatically in the cloud in accordance with their Project assignments.
To create a project go to SvanNET via SvanNET app, open Project List / New Project:
SvanNET Projects
Automatic Download
Once a project is created then data from an SV 307 can be automatically down-
loaded to the SvanNET servers with the Automatic File Download (AFD) function.
AFD ensures that data has been safely downloaded and shared before clearing the
memory in the remote SV 307 on site to maintain maximum storage space.

In accordance with best measurement practices and ISO 1996-2 if measurements
take place over longer periods of time, e.g. over a day or more then the meas-
urement system should be checked either acoustically or electrically at regular
intervals, e.g. once or twice a day.
Following the ISO 1996-2 recommendations the SV 307 has been equipped with
an Acoustic System Check (ASC) that can be activated remotely; either auto-
matically or upon manual request. The ASC is located in the top of the tube direct-
ly above the microphone of the SV 307.
System Check
The ASC is based on a small speaker and the three MEMS microphones in the
SV 307. Activation of the ASC enables the speaker and triggers an alarm if any of
the three MEMS microphones reports a different noise level than the others.
Remote System Check
System check configuration is available in SvanNET Configuration tab. Simply go
to SvanNET / Configuration / Calibration - Automatic System Check to schedule
the system check time.
System Check in SvanNET APP
To perform a manual system check simply open SvanNET application, select your
SV 307 station and click the System Check button.

The SV 307 is delivered with a waterproof power supply. If it happens that AC
mains powering is not available, the internal battery can power the SV 307 for
up to 6 days. The battery life can be extended with a simple cable connection of a
solar panel or external battery to DC-IN socket in SV 307.
Powering
Use of Solar Panel
Optionally the SB 371 solar panel (40 W) can be used to extend the autonomy of
SV 307. The SB 371 is simply connected to DC-IN socket in SV 307 with a SC 333
cable. The efficiency of charging the internal battery from solar panel depends
on the amount of sunlight available locally. In cloudy conditions (e.g. in Poland)
a minimum of 130 W solar panel is needed to supply enough power to ensure
continuous operation of SV 307.
Use of External Battery
Optionally the SB 275 external battery (33 Ah) can be used to extend the autono-
my of SV 307. The SB 275 is simply connected to DC-IN socket in SV 307.
The SB 272 should be recharged with its included dedicated charger unit
Calibration
In accordance with ISO 1996-2, imme-
diately before and after each series of
measurements, a class 1 sound calibrator
in accordance with IEC 60942:2003 shall
be applied to the microphone to check
the calibration of the entire measuring
system at one or more frequencies.
To properly calibrate the SV 307 with a
separate acoustic calibrator go to the
main menu then Calibrate by Measure-
ment.
It is necessary to carefully remove the up-
per straight tube with the anti-bird spikes
to apply the calibrator cavity directly over
the microphone of the SV 307.
Be careful not to remove the locking
sleeve for the microphone itself when
calibrating.
