SVAN 979 USER'S MANUAL_______________________________________________ _7
1. INTRODUCTION
The SVAN 979 is all digital, Class 1 Sound & Vibration level meter (SLM
and VLM) as well as a real time 1/1, 1/3 octave analyser. The instrument
is designed for general acoustic and vibration measurements,
environmental monitoring, occupational health and safety monitoring.
Three acoustic or vibration user configurable profiles allow parallel
measurements with independently defined frequency filters and RMS
detector time constants. Each profile provides a significant number of
results (like Spl,Leq, SEL, Lden, LEPd, Ltm3, Ltm5, LN%, LR15,
LR60, Ovl, Peak, Max, Min in case of sound measurements or RMS,
Ovl, Peak,P-P,MTVV in case of vibration measurements). Advanced
time history logging for each profile provides complete information about
the measured signal using the external SD-card or USB Memory Stick
and can be easily downloaded to any WindowsTM PC using the USB
interface and SvanPC++ software.
All required frequency weighting filters (e.g.: A, B, C, G, Zin case of
sound measurements are available with this instrument. General
vibration measurements (acceleration, velocity and displacement) are
also available.
Standard version of SVAN 979 is equipped with 1/1 and 1/3 octave real-
time analysis as well as FFT. In the sound level meter mode the statistic
analysis in 1/1 or 1/3 octaves is also available. Frequency analysis is an
essential tool for sound & vibration engineers. Depending on an
application it can be more or less detailed. For advanced applications that
require the narrow band frequency analysis, SVAN 979 offers options of
the 1/6* or 1/12* octave real-time analysis.
The frequency analysis is a critical tool in building acoustics
measurements. Depending on the application, frequency analysis can be
done in 1/1 octave or 1/3 octave spectra. SVAN 979 records the time
history of spectra with milliseconds logging step. It enables one to
calculate RT60 results as well as sound insulation results. Additionally
SVAN 979 offers the functionality of a signal generator which is capable
of generating pink noise, white noise or a selected sine wave. The signal
generator works together with the RT 60 function which is calculated in
1/1 or 1/3 octave bands.
Another feature of SVAN 979 is a time signal recording, which stands for a recording of the raw signal
samples with defined frequency up to 48 kHz. Analysis of the raw signal is used whenever frequency
analysis is not sufficient. Postprocessing of wave files such as calculation of tonality is available in
SvanPC++ program. Time signal is recorded in a wave format which means that it can be played back in
the PC software and used for noise source recognition (audio recording).
A fast USB 1.1 interface (12 MHz) creates a real time link for the PC "front-end" application using the
SVAN 979. The USB Host functionality is also available. The USB Host controller installed in the instrument
enables the user to connect this meter to USB memory sticks, USB hard disks, USB printers etc. With the
use of optional interfaces (RS 232, Bluetooth®1or IrDA) the instrument can be remotely controlled from the
PC or smartphone. Measurement results can be downloaded to the PC using all the interfaces mentioned
above.
Working as a part of SV 279 PRO monitoring station, equipped with 3G modem, SVAN 979 can transfer
measured data via Internet to the PC with the use of SvanPC++_RC option or via SvanNET Web service.
The instrument can be fully remotely controlled via these interfaces. The instrument has extended alarms
features, that enables the user notification about exceeded threshold levels by SMS or mails.

SVAN 979 USER'S MANUAL_______________________________________________ _10
2. MANUAL CONTROL OF THE INSTRUMENT
Control of the instrument has been developed in a fully interactive manner. The user can operate the
instrument by selecting the appropriate position from the selected Menu list. Thanks to that, the number of
push-buttons for control of the instrument has been reduced to nine for ease of use and convenience.
2.1 Control push-buttons on the front panel
The following control push-buttons are located on the front panel of the
instrument:
•<ENTER>,(<Menu>),[<Save>],
•<ESC>, (<Cal.>),[<S/P>],
•<Shift>, [Markers]
•<Alt>, [Markers]
•<>,
•<>,
•<>,
•<>,
•<Start/Stop>.
The name given in (...) brackets denotes the second push-button function
which is available after pressing it in conjunction (or in sequence) with the
<Shift> push-button. For the first two push-buttons the name given in
square brackets […] denotes also the third push-button function which is
available after pressing it in conjunction (or in sequence) with the <Alt>
push-button.
<Shift>
The second function of a push-button (written in red colour on a push-button) can be used
when the <Shift> push-button is pressed. This push-button can be used in two different ways:
•as Shift like with a computer keyboard (e.g. while typing the filename); both <Shift>
and the second push-button must be pressed together (two finger operation);
•as 2nd Fun; this push-button can be pressed and released before pressing the
second one or pressed in parallel (while operating in “2nd Fun”mode, see the
following notice) with the second push-button (one finger operation).
The <Shift> push-button pressed in conjunction with <Alt> enables the user to activate the
Markers on the plots during the measurement.
<Alt>
This push-button enables the user to choose the third push-button function in case of [<Save>]
and [<Pause>] push-buttons. In order to select the third function the user must press the <Alt>
and the second push-button simultaneously.
Notice: Simultaneously pressing the <Alt> and <Start/Stop> push-buttons switches the
instrument on or off.
<Start/Stop
>
This push-button enables the user to start the measurement process, when the instrument is
not measuring or to stop it, when the instrument is in course of the measurement. It is also
possible to set the mode of this push-button such that in order to start or stop the
measurements the user has to press it simultaneously with the <Shift> push-button. This can
prevent accidentally starting or stopping a measurement at the wrong time by just brushing
against the Start/Stop button on its own.
Notice: Changing the <Start/Stop> push-button mode is performed in the
Keyboard Settings window of the Instrument list (see description of the Instrument list).

SVAN 979 USER'S MANUAL_______________________________________________ _11
<ENTER>
This push-button enables the user to enter the selected position shown on the screen Menu
list or to confirm selected settings. Some additional functions of this push-button will be
described in the following chapters of this manual.
(<Menu>)
This push-button (pressed together with <Shift>) enables the user to enter the main list
containing seven sub-lists: Function, Measurement, Display, File, Instrument,
Auxiliary Setup and Report. Each of the above mentioned menu lists consists of sub-lists,
elements and data windows. These main sub-lists will be described in detail in the following
chapters of the manual. Double pressing the <Menu> push-button enters a list containing the
last eight opened sub-lists. It often speeds up the control of the instrument as the user has
faster access to the most frequently used sub-lists for easy navigation.
[<Save>]
This push-button (pressed together with <Alt>) enables the user to save measurement results
as a file in the instrument’s internal memory or on the SD-card or USB memory stick. There
are two available functions: Save Next - save a file with the name increased by one (e.g.
02JAN0, 02JAN1, 02JAN3) and Save - save a file with the edited name.
<ESC>
This push-button closes the control lists, sub-lists or windows. It acts in an opposite way to the
<ENTER> push-button. When the window is closed after pressing the <ESC> push-button,
any changes made in it are ignored in almost all cases.
(<Cal.>)
This push-button (pressed together with <Shift>) opens the Calibration sub-list.
[<S/P>]
This push-button enables the user to pause or break the measurement process temporarily. If
there is no current running measurement in progress this push-button opens the Setup
Manager menu.
<>, <>
These push-buttons enable the user specifically to:
•select the column in a multi column parameter list;
•select the parameters value in an active position (e.g. filter Z, A, Bor C, Integration period:
1s, 2s, 3s … etc.);
•control the cursor in Spectrum, Logger and Statistics modes of result’s presentation;
•select the position of the character in the text editing screen;
•activate markers 2 and 3
•speed up changing the numerical values of the parameters when pressed and held.

The <>, <>push-buttons pressed in conjunction (or in sequence) with <Shift> enable the
user specifically to:
•change the parameters value with double step (e.g. Start Delay period: form 1s to 11s, 21s
… etc.);
•to shift cursor from the first to the last position and back on the graphical presentation mode
(except 1/6 and 1/12 octave spectrum presentation);
•zoom in or zoom out in the 1/6 and 1/12 octave spectrum presentation modes.
[<>, <>]
The <>, <>push-buttons pressed in conjunction (or in sequence) with <Alt> enable the
user specifically to:
•select the parameters value in an active position in the matrix parameter list;
•select the parameters value in an active position (e.g. filter Z, A, Bor C, Start Delay period:
1s, 2s, 3s … etc.);
•insert or delete a character in the text edition screen.
<>, <>
The <>, <> push-buttons enable the user specifically to:
•select lines in the list;
•select the correct character from the list in the text edition screen;

(<>, <>)
The <>, <> push-buttons pressed in conjunction (or in sequence) with <Shift> enable the
user specifically to:
•shift the cursor from the first to the last position and back on the menu list;
•change the relationship between the Y-axis and X-axis of all plots presented on the screen.

SVAN 979 USER'S MANUAL_______________________________________________ _12
[<>, <>]
The <>, <> push-buttons pressed in conjunction (or in sequence) with <Alt> enable the
user specifically to:
•change the mode of result presentation;
•programme the Real Time Clock (RTC) and Timer.
[Info]
The <Info> push-button (simultaneous pressing the <>,
<> push-buttons) opens the window with the help
information in the measurement display modes. Press
<ESC> or <ENTER> to exit the Info screen.
[Markers]
The Markers enable the user to mark special events, which occurred during the performed
measurements (i.e. the airplane flight, the dog barking, the train’s drive etc.). In order to
activate the markers the logger has to be switched on (path: <Menu> / Measurement / Logging
/ Logger Setup) and one or more logger results (Peak, Max, Min, Leq for sound
measurements or Peak, P–P, Max, RMS for Vibration measurements) in profiles have to be
activated (path: <Menu> / Measurement / Logging / Logger Results).
In order to enter the marker mode the user must press <Shift> and <Alt>
push-buttons simultaneously during the measurement. Then four
available markers appear on the screen. To choose marker number 1 the
user must press <>push button (number 2 - <>, number - 3 <>
and number 4 - <>).
The markers disappear automatically and the chosen marker is activated
(after pressing <Shift> + <Alt> again active marker number will be
highlighted). In order to switch off the marker, the user has to press
<Shift> + <Alt> and press the arrow push-button, which refers to the
marker to be switched off.
The current state of the markers is indicated in the logger file (cf. App. B
for details) and can be used to show them with the help of the dedicated
presentation software.
An example presentation of the markers on the time history plot is shown
below (to view a plot with markers the user has to transfer data to the

2.2 Input and output sockets of the instrument
Top cover of the instrument
The measurement input is placed in the centre of the instrument’s top
cover. It is the Lemo-7 compatible socket. The SV 17 microphone
preamplifier has a specially designed matching plug and a locking screw
to secure the preamplifier to the meter body. The accelerometers have to
be connected to the instrument also using the Lemo-7 connector. After
connecting the preamplifier or the accelerometer cable to the
measurement input, the screw should be tightened to light resistance
only. Do not over tighten this connector. It is not necessary to remove this
preamplifier from the top of the instrument unless the meter is in a
calibration laboratory as it is always used close coupled to the meter
body. The full description of the signals connected to the sockets is given
in Appendix C.
Bottom cover of the instrument
In the bottom cover there are four sockets, placed from the right to the
left as follows: Ext. 6-24Vdc, USB Host, USB Device and I/O.
There is a micro SD memory-card socket under the bottom cover of the
instrument and spaces for the 4 x AA batteries.
The USB Device 1.1 interface is the serial interface working with 12 MHz
clock. Thanks to its speed, it is widely used in all PC. In the instrument,
the standard 4-pin socket is used and described in detail in Appendix C.
The USB Host 1.1 interface can be used to connect an external USB
Memory Stick or USB hard disk, enabling the device to register virtually
infinite sequence of measurement results.
The additional multi-purpose input / output socket, called I/O, is a two-pin
LEMO socket. On this socket, in the case when the Analogue Output
functionality is selected, the signal from the input of the analogue / digital
converter (before any frequency correction) is available. This signal can
be recorded using magnetic recorder or observed on the oscilloscope.
The Digital Input is another functionality that serves as the external trigger
to the instrument, while the Digital Output is used to generate the trigger
pulse or alarm pulse from the instrument.
The user can connect an external DC power 6-24V adapter to the 6-24V
socket located on the bottom cover of the instrument. The current
consumption depends on the voltage of the power supplier.
Notice: Switch the power off before connecting the instrument to any other device (e.g. a
printer or a Personal Computer).

3. SETTING THE INSTRUMENT
In order to perform measurements using the instrument the user only has to plug-in the preamplifier with the
microphone already screwed on or the proper vibration transducer and to switch the power on by pressing
of the <Alt> and <Start/Stop> push-buttons at the same time. Hold both buttons down for 1 or 2 seconds
and release to switch on.
3.1. Basis of the instrument’s control
The instrument is controlled by means of nine push-buttons on the keyboard. Using these push-buttons the
user can access all available functions and change the value of all available parameters. The functions are
placed in a system of lists and sub-lists.
The instrument's menu consists of different type of windows, which include: main menu list, sub-menu list,
option list, parameter list, text editor window, information window and file manager window with file command
list.
Main menu
The main list contains the headers of seven lists, which also contain sub-
lists or positions (elements). The main list is opened after pressing the
<Menu> push-button. This list contains the following sub-lists: Function,
Measurement, Display, File, Instrument, Auxiliary Setup and Report.
Recent Items list
Double pressing the <Menu> push-button opens the list of recently
accessed menu items. This enables the user to access the most
frequently used lists quickly, without the necessity of passing through the
whole menu path.
Position selection
The desired position in menu list is
selecting using the <>or <>push-
buttons.
<>
Entering selected position
After selection of the desired position in
the menu list, the user has to press the
<ENTER> push-button in order to enter
it. After this operation a new sub-menu,
option list, parameter list or information
window appears on the display.

List of parameters
The parameter list contains parameters for which the user may select the
value from the available range. Pressing the <ENTER> push-button
enables the user to access the above mentioned sub-lists.
▪The desired position in a list is accessed after pressing the <>or
<>push-button.

SVAN 979 USER'S MANUAL_______________________________________________ _15
▪The change of the value in a selected position is performed by the
<>or <>push-buttons (or pressed together with <Shift>).
Option list
The option list consists of different choices, from which only one may be
selected. The selection of the option is performed as follows. The user
has to highlight the desired option by means of the <>or <>push-
buttons and then press <ENTER>. This option became active and the list
is closed. When the user re-enters this list again the last selected option
will be marked.
If the parameter has a numerical value the user may keep pressing the <>or <>push-buttons (or
pressed together with <Shift>) longer than 1 second to speed up the selection. In this case the parameter
starts to change automatically until the user releases the pressed buttons.
The user may change the numerical parameter value with a larger step (usually 10, 20) by means of the
<>or <>push-buttons pressed together with <Alt>.
Matrix of parameters
When the list of parameters consists of more than one column the user
may change:
▪column by means of <>or <>
▪line in the same column by means of <>or <>
▪value in a selected position by means of <>or <>with <Alt>
▪all values in the same column by means of <>or <>with <Shift>
▪all values in the same line by means of <> or <>with <Shift>.
Complex parameters
Some parameters like Start Hour,
Start Day etc. are complex (consisting of
more than one value field). The selection of
values for such parameters is performed in
a special window, which is opened with the
<>or <>push-buttons. In the special
window the value is selected with the f <>,
<> or <>, <> push-buttons and then
is confirmed by pressing <ENTER>.
In all cases the <ENTER> push-button is used for confirmation of the selection in a position and for closing
the opened sub-list. The sub-list is closed ignoring any changes made the list by pressing the <ESC> push-
button and the user returns to the previous menu.
Information window
Some windows inform the user about the state of the instrument,
available memory, none existing files or loggers, standards fulfilled by the
unit, etc. In order to scroll through the list, the user has to use the <>
or <>push-button. In order to close such a window, the user has to
press <ESC>.
Text editing window
There are also windows, in which the user may edit some text (i.e. the
name of the file). This window contains help information to guide the user
how to edit the text. The character which is displayed inversely may be
edited.
▪The user can select the position of the character in the edited text
using the <>, <> push-buttons.

SVAN 979 USER'S MANUAL_______________________________________________ _16

<>, <> push-buttons pressed together with <Alt>.
<>
Help information
In most windows the last line or several lines at the bottom of the screen contain help information. It informs
the user how to select or modify the parameter’s value, change the character in the text line etc.
Inactive parameters
If some functions or parameters are not available, the positions in the
menu or parameter lists linked with this function or parameter became
inactive (their colour became grey). For example, if Logger (path:
<Menu> / Measurement / Logging / Logger Setup) is switched off the
Logger presentation mode is not active!
3.2. Powering of the instrument
The SVAN 979 can be powered by one of the following sources:
•External DC power source –6 V DC÷24 V DC (1.5 W)
•SA 17A external battery pack –operation time > 24 h (option)
•Four AA standard size internal batteries. In the case of alkaline type, a new fully charged set can
operate more than 12 h (6.0 V / 1.6 Ah). Instead of the ordinary, four AA rechargeable batteries can
be used (a separate external charger is required for charging them). In this case, using the best NiMH
type, the operation time can be increased up to 16 h (4.8 V / 2.6 Ah)
•USB interface –500 mA HUB
For each of the three kinds of possible power source there is a different view presented in the Battery window
of the Instrument list.
When the instrument is powered from its internal batteries, the “Battery” icon is presented on the top line of
the display. When the voltage of the batteries is too low for reliable measurements, the icon is red or during
attempt to switch the instrument on the Low Battery! message occurs on the display for 2 seconds and the
instrument switches off by itself. A fully charged set of 4 batteries ensures more than 12 hours of continuous
operation of the instrument (with Dim LCD switched on). The battery condition can be checked by means of
the Battery function. It is also presented continuously on the top line of the display by means of the “Battery”
icon.
When there is a connection to the USB interface (USB Device socket is
connected by means of the cable to a PC), the “computer” icon is
presented on the top of the display and in the Battery window there is
the USB Power: Voltage: x.xxVmessage.

SVAN 979 USER'S MANUAL_______________________________________________ _17
When there is a connection to the 6–24Vsocket, the “plug”icon is
presented on the top of the display and in the Battery window there is
the External Power: Voltage: yy.yyVmessage.
When the instrument is powered from
the internal batteries the “battery”icon
is presented on the top of the display
and the Battery window presents the
battery status scale and battery voltage
Voltage: x.xx. The colour of the
battery and the scale reflects the
battery capacity: green (>75%), yellow
(>25%), red (<25%).
<>
To have right indication of the battery status the user should select the battery type in the Type position:
Alkaline or Rechargeable.
Notice: In case when “Battery” icon is red, it is strongly recommended to use an external power
adapter or USB interface as soon as possible to ensure reliable operation. If no suitable external
power source is provided the instrument will be switched off automatically after a short time!
Prolonging the internal source of the instrument’s power can be achieved by reducing the brightness of the
screen when possible. The settings of Brightness and power saver function may be done in the
Screen Setup window (path: <Menu> / Display / Screen Setup).
3.3.Starting the instrument
Switching the instrument on
To switch the power on the user should press the <Alt> and <Start/Stop>
push-buttons at the same time. The instrument goes through the self-test
routine after switching on (displaying the manufacturer and the name of
