1 INTRODUCTION

The SV 102 is digital, type 2 dual-channel dosimeter dedicated for occupational health and safetyacoustic monitoring task. The binaural dose measurements and the 1/1 octave analysis aresimultaneously performed. Octave analysis provides direct data for the design of the ear-protectors.Together with Audio Events Recording (AER) option, these functionalities show the new reference

standard on the acoustic dose measurement field, now commonly available in compact size instrument.

Dosimeter is offered with one or two dedicated SV 25D ceramic microphones in ½” housing.It ensures the very easy calibration by direct usage of commonly available acoustic calibrators. Moreover,SV 25D smart sensor, with built-in TEDS (Transducer Electronic Data Sheet), offers automatic calibrationfunction. The very robust casing of SV 25D, together with the special mounting clip and dedicatedheadband, make that microphones can be very easy attached in extremely short distance from the humanears.

SV 25S smart sensor with TEDS, is dedicated for the measurements under headphones orearmuffs using MIRE technique (Microphone-In-Real-Ear). With a special adapter, it can be alsocalibrated with commonly available acoustic calibrators. The SV 102 together with SV 25S are designedfor individual real-world test of the earmuffs noise reduction ratio.

The SV 102 can be also used as a dual-channel type 2 sound level meter and real-time 1/1 octaveanalyser. Three acoustic profiles per channel allow parallel measurements with independently definedfilters and RMS detector time constants. Advanced time-history logging for each profile, togetherwith spectra saving and audio-events recording provide complete information about measured signal,which is saved in non-volatile internal memory with the capacity up to 64 MB. Data files are easilydownloaded to any PC using USB interface and SvanPC+ software.

Instrument is powered from two AA standard or rechargeable batteries (separate chargeris required) as well as the USB interface.

2 MANUAL CONTROL OF THE INSTRUMENT

The control of the instrument is developed in the fully conversational way. User can managethe operation of the instrument by selecting the proper option from the Menu. Thanks to that,the number of the control push-buttons of the instrument is reduced to four.

2.1 Control push-buttons on the front panel

On the front panel of the instrument, there are located the following control push-buttons:

1. <Shift>, (backlight - if held),

2. <>, (<> if pressed with <Shift>)

3. <>, (<> if pressed with <Shift>)

4. <ENTER>, (<ESC> if pressed with <Shift>, <On/Off> if held)

Control push-buttons of the SV 102 instrument

<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 in the keyboard (e.g. while typing the filename); both <Shift> and the second push-buttonmust be pressed in parallel;

• As 2nd Fun, this push-button can be pressed and released before pressing the second one orpressed in parallel (while operating in “2nd Fun” mode, see the following notice) with

the second push-button.

Notice: The operation of this push button can be set as the “Shift” mode or the “2nd Fun.” mode in the KEYBOARD window of the SETUP list (see Chapter with the SETUP list description).

Notice: <ENTER> push-button held for at least 5 seconds switches the instrument on and off.

Start/StopThe Start/Stop (<> pressed together with <ENTER>) enables one to start the measurement

process, when the instrument is not measuring or to stop it, when the instrument is in courseof the measurement.

<ENTER>

This push-button enables one to enter the selected operation mode or to confirm control options.

MenuThe Menu (<> and <> pressed together) enables the user to enter the main list containing six

sub-lists: FUNCTION, CALIBRATION, INPUT, DISPLAY, FILE and SETUP. Each of the mentioned

above sub-lists consists of the different elements. These main sub-lists will be detailed describedin the following chapters of the manual. Double pressed Menu enters the list containing eight last opened

sub-lists. It often speeds up the control of the instrument.

SaveThe Save (<> pressed together with the <ENTER>) enables the user to save measurement

results as a file in the internal instrument’s memory. There are two available functions: SAVE NEXT - savea file with the name increased by one (e.g. 02JAN0, 02JAN1, 02JAN3) and SAVE - save a filewith the edited name. (AUTO SAVE option is implicitly set in the instrument to save each file automatically

after the measurement)

<ESC>This push-button (<Shift> pressed together with <ENTER>) closes the control lists, sub-lists or

windows. It acts in opposition to the <ENTER> push-button. When the window is closed pressingthe <ESC> push-button, any changes made in it are ignored in almost all cases.

<>, <>

These push-buttons enable one, in particular, to:

• select the options in an active position in the "horizontal direction" (e.g. Integration period: 1s, 2s, 3s,

… etc.),

• select the measurement result to be displayed (e.g. PEAK, MAX, MIN, etc.) in One Profile and3 PROFILES modes of result’s presentation),

• control the cursor in LOGGER and STATISTICS modes of result’s presentation,

<>, <> The <>, <> (<>, <> pressed together with <Shift>) push-buttons enable one, in particular,

to:

8.2 Controlling the data storing in the instrument’s memory - SAVE OPTIONS

The SAVE OPTIONS is used for the selection of the options of data storing in the flash memory

of the instrument.

FILE window with SAVE OPTIONS text highlighted

It is possible to write data into the same part of the memory starting all the time with the sameaddress (RAM FILE), to replace the existing in the memory file by the new with the same name(REPLACE), to add to the results the statistics of the measurements (SAVE STATISTICS), to saveautomatically the results of the measurements (AUTO SAVE).

8.2.1 Saving data starting from the same address - RAM FILE

The RAM FILE functionality is available only in the SLM and SLM&1/1 OCTAVE analysis modes.

The measurement data usually are saved in the different files in the flash memory of the instrument.

It means that each time the data are saved the previous file is overwritten.

This option is useful for the permanent monitoring and remote reading data from the instrumentby means of any available interface with the proper period. In order to read data saved in a RAM file onehas to use #4,3 function described in details in App. A.

8.5 Removing all files with measurement results from memory - DELETE ALL

The DELETE ALL is used to remove all files from memory. The DELETE ALL consists of threepositions: RESULT FILES, LOGGER FILES and SETUP FILES. The deleting of those three types of files

is performed in the same way (shown below). In order to delete all result, logger or setup files the user hasto select type (types) of files to be deleted, press <ENTER>, confirm the selection and press <ENTER>

again.

<>

<ENTER>

Deleting all files

Notice: The execution of the DELETE ALL function described above takes place in the case

when only one type of the files is selected in the DELETE ALL window. If all types are selected simultaneously and the logger, result and setup are saved, only Clearing operation is performed but two times – one time in logger files memory and one time in result and setup files memory. After clearing all memory, the defragmentation is not done. The memory merging is done only in the case of setup and results memory, as these two different types of files are saved together in the same space.

8.6 Merging file space - DEFRAGMENTATION

The DEFRAGMENTATION is used to make the file memory continuous. All new files are saved

starting from the beginning of the free memory space. The memory occupied by the deleted file, assuming

that the file was not the last one, remains unused for the next files saving. After the removinga file the files memory becomes discontinuous, with unused parts, which cannot be utilized in the future.The situation is changed after the process called defragmentation. During this process, the files savedin the files memory are moved in order to obtain the continuous occupied space.

The files’ merging is performed separately for two parts of the instrument’s memory:the FILES DEFRAGMENT. is used to join the result and setup files and LOGGER DEFRAGMENT. is used in the case of the logger. Before the defragmentation the FILES FREE SPACE andTOTAL AVAILABLE, characterizing the result memory (path: FILE / FREE SPACE ), usually differ

between each other. After this operation, these two parts are equal. The same situation is in the caseof the LOGGER FREE SPACE and TOTAL AVAILABLE characterizing the logger file.




8-14

CATALOGUE window when the memory is empty

In the case when the result and setup files memory in the instrument is not empty (some filesare stored) another window is displayed in which the same data about the existing in the instrument filesas in the FILE / LOAD window are presented. The current number of the file and the total number

of the saved result and setup files is displayed in the first line of the window. The name of the fileis displayed in the second line (its current number is presented in the first line). The name of the filesuggests the operation the file was created-in.

The names in which the first character is @ are coming from the AUTO SAVE function.

The file with the default name @Timer@ is coming from the AUTO SAVE function executedin the TIMER operation. The other names suggest the SAVE / SAVE NEXT function. The type

of the current file (DOSE METER, DOSE & 1/1 OCTAVE, SLM or SLM & 1/1 OCTAVE) is givenin the third line. If during the measurements which results are saved in the file, the logger file was alsocreated its name is displayed in the fourth line.

Notice: The logger file can be deleted from the instrument’s memory in the FILE / DELETE / LOGGER FILES window and this deleting operation does not modify the contents of the fourth line of the CATALOGUE window.

The date and time of the SAVE operation are displayed in the fifth and sixth line, respectively.The change of the current file can be done after pressing the <>, <> push-buttons. The setup file is

indicated by the SETUP text displayed in the third line instead of the DOSE METER / DOSE&1/1 OCTAVE / SLM / SLM&1/1 OCTAVE text.

9.5.1 Mode selection of the Ext. I/O port - MODE

In the MODE, it is possible to select the function of the instrument’s socket named as Ext. I/O.This socket can be used as

•The output of the analogue signal (ANALOG OUT) transmitted from the input of the instrument to itsoutput without any digital processing (i.e. filtering).

• The input of the digital signal used as an external trigger to start the measurements ( DIGITAL IN)in the “slave” instrument; (this mode is available for RIGHT CHANNEL).

• The digital output (DIGITAL OUT) used for triggering other “slave” instrument from the “master” one(this mode is available for LEFT CHANNEL).

• The source of any alarm signal in the case of certain circumstances occurred duringthe measurements (i.e. the level of the input signal was higher than selected one).

The more detailed description of the Ext. I/O is given in App. C.

In the case of DIGITAL IN (RIGHT CHANNEL) selection the signal appearing on the Ext. I/O socket will be treated as the external trigger if the EXT. I/O is chosen (path: INPUT / TRIGGER SETUP / MEASURE TRIGGER / SOURCE / EXT. I/O ) and it can be set only if SLOPE + or SLOPE – was setas a TRIGGER (path: INPUT / TRIGGER SETUP / MEASURE TRIGGER / TRIGGER ).

The formulae used for the LEQ calculation are given in Appendix D. Setting LINEAR is requiredfor getting the true RMS value of the measured signal. When this option is selected the value of the LEQ,Lden, LEPd, Lxx and SEL functions do not depend on the detector time constant: Fast, Slow or Impulse (the results are displayed without the indicator of the detectors selected in the profiles). In this case,the indicator Lin. (or L) is displayed in different modes of measurement results presentation. SettingEXPONENTIAL enables the user to fulfil the requirements of another standard for the LEQ measurements. When this option is selected the value of the LEQ, Lden, LEPd, Lxx and SEL functiondepends on the detector time constant (the results are displayed with the indicator of the detectorsselected in the profiles (path: INPUT / PROFILE x / DETECTOR: Fast, Slow or Impulse ).

9.11.5 Description of the exemplary timer function execution

The TIMER function is used to programme the instrument’s switch on at the preset time andperform the measurements with the parameters set in the INPUT window.

Let’s assume that the user want to switch on the instrument the 1st

of February, at 13:25, measuresound during 15 minutes without using logger and save the results in a file @RES2.

In order to do this the user has:




9-12

• to set the parameters of the TIMER function (path: SETUP / TIMER ),

• to set the measurement parameters (path: INPUT / MEASUREMENT SETUP ),

• to activate the AUTO SAVE function (path: FILE / SAVE OPTIONS ),

• to name the file (the FILE NAME window is opened after switching on the AUTO SAVE function) and

• to switch off the instrument.

Exemplary settings made for the desired execution of TIMER function

The instrument will be switched on the 1st

of February at 13:25 and will be warmed upfor the period of 60 seconds decrementing by one after each second the counter visible on the display.

..

Counting down during the warming up of the instrument after switching it on

After warming up the instrument and the preset DELAY time, the measurements are performedfor a period of ten seconds. Then, the results are saved in the file which name was given or accepted(the proper information is displayed) and finally – the instrument is switched off.

Displays during the executing of TIMER function (TIMER icon is active)

Notice: The instrument’s TIMER function can be used for multiply measurements (at the programmed day and time with the selected repetition). The first switch on of the instrument must be within one month ahead.

Notice : In the case when the AUTO SAVE option is switched off the measurement results will be saved automatically in the file with the @Timer@ name. If the @Timer@ file exists already,the new file replaces the old one.
