1. Introduction
The DS200 noise dosimeter is measuring instrument allowing measurement of sound exposure at workstation.
In accordance with international standards, DS200 calculates values usuall used for comparison with regulations on
exposure value.
With its memor , DS 200 instrument stores measurement dataset. Then the are transferred on a computer and
processed through LDS23 software supplied with the instrument.
The optional LDS300 software will allow a more detailed anal sis in accordance with EN ISO9612 : 2009 standard.
In addition, this noise dosimeter contains a conventional sound level meter function for a first estimation of the noise
environment of workplace
DS200 comes in a small case with ergonomic design. It can be easil put on a belt or in a pocket of people at workstation.
The microphone, at the end of the extension, is attached thanks to the kit speciall developed to minimize the disruptions
caused b impact or clothes frictions.
Measurements are stored in a MicroSD memor of large capacit giving to the whole a measurement capacit almost
unlimited.
With its backlighted LCD screen, DS200 is also a conventional and integrating-averaging sound level meter for a a quick
estimate of the noise in the workplace.
In measurement mode, it can inform person about the levels through a two coloured light.

2. Generality
2.1. Regulation
The prescriptions regarding the exposure of workers to the risks are mentioned in the 2003/10/EC European Directive.
From these controls, the obtained results are compared to defined regulator action thresholds.
These thresholds are based on two parameters :
•the dail noise exposure level (Lex, 8h in dBA)
•the C frequenc -weighted LCpeak peak pressure level
In case of threshold excesses, actions have to be done. The regulation specifies two action thresholds that lead to
preventive actions :
•lower exposure value – Lex;8h>80 dBa and LCpk>135 dBC
•upper exposure value – Lex,8h>85 dBA and LCpk>137 dBC
These two thresholds are complemented b a third one called Exposure Limit Value, which should not be exceeded under
an circumstances :
•Lex,8h> 87 dBA and LCpk > 140 dBC
2.2. Labour law
It is mainl based on Articles R4433-1, R4433-2 and R4433-7 and complemented b the Decree of Jul 19, 2006.
2.3. Measurement
It is mainl based on Articles R4433-1, R4433-2 and R4433-7 and complemented b the Decree of Jul 19, 2006.
The measurement must be done in compliance with prescription of the EN ISO9612:2009 standard.
Principle :
the standard recommends three methods of measurement :
•b task
•b profession or function
•b full da
This standard also adds the measurement processing including the estimation of measurement uncertaint .
2.4. Noise exposure – Exposure points
This simplified method is well adapted for workers whose workstation is constituted b several identifiable tasks. The
difficult of “summons” dB levels does not allow a fast approach of the dail nose exposure level, using this method
provides a ver significant operational flexibilit .
It takes into account nose exposure expressed in Pa2h of various tasks that can be added to get an dail global nose
exposure. From that, determination of Lex,8h dail exposure becomes easier with a research in a dedicated corresponding
table. This table is available in the ED6035 document published b the INRS.
DS200 dosimeter calculates noise exposure and displa s on its screen the number of exposure points of the task
performed b the worker on his workstation.

6. Calibrate the instru ent
Before each measurement series, a calibration must be performed with an appropriate calibrator. A control shall be also
performed at the end of the measurement. The deviation between both calibrations must not be higher than 0.5 dB. If this
deviation is higher than 0.5 dB, the performed measurements are questionable.
Reminder :
A reference source of noise such as a calibrator supplies a noise pressure level. During a free field measurement,
phenomenons of diffraction caused b the microphone and the housing come to disrupt the measurement. This disruption is
minimized if the microphone is far from the housing. For the DS200, the induced disruption in free field is ver weak, it is not
necessar to introduce a free field correction.
6.1. Perform the calibration
From the starting screen :
➢Press Cal.
The instrument displays a new screen.
➢Check that the reference value and the free field Cr.CI correction value correspond to the
calibrator used (0.0 dB for DS200).
➢Turn on the calibrator and put it on the microphone.
➢Put the cursor on V1.
The instrument automatically adjusts the gain of the channel to obtain the coincidence of the levels
displayed in Ref and V1.
When the measurement is stabilized, a pictogram OK appears.
➢Press 3 key to validate.
At this moment the correction value of the gain and calibration date are memorized and visible for the ne t
calibration.
➢Quit calibration function pressing 4 key.
Note : This correction can not exceed +/- 2 dB. If the correction exceeds +/- 2 dB, the coincidence values in Ref and LCF
is not obtained. Reasons of this difference shall be identified (defective microphone, level value of the calibrator not
adapted...).
6.2. Modify the reference value
The preset reference value during manufacturing process shows that we use calibrator with rated value
of 94 dB at 1000 Hz. To modif it :
➢Put the cursor on Ref with 2 or 3 key.
➢Adjust at the required value, dB per db.

8. Noise dosi eter-integrator-averager
➢Press 2 key from the starting screen.
The DS200 processes the sound pressure signal and displa s the following informations according to
the initial setting :
•the equivalent continuous level of A (A and C) weighted sound pressure for each duration of
logging time – LAeq,DI and LCeq,DI
•the equivalent continuous level of A (A and C) weighted sound pressure on the current
measurement duration – LAeq,T and LCeq,T
•the maximum peak level of sound pressure on each duration of logging time : LCpK
•the duration measurement in DD/HH:MM:SS
The measurement parameters will be set in advance in “Prog.measurement” menu. It means :
•to set the duration of logging time of the equivalent continuous level
•to select the C or Z weighting of the sound peak pressure level
•of the measurement of the A-weighted equivalent continuous level onl or simultaneousl with both A and C
weightings
•of the activation or not of the visual alarms
2 selections of d namic ranges are possible :
•60-140 dBA for the measurement of sound atmospheres in a nois industrial environment
•40-120 dBA for the measurement of sound atmospheres in services sector or low nois industrial environment
➢Select the d namic range pressing 1 key according the following coding :
•“40” pictogram : 40-120 dB d namic range
•“60” pictogram : 60-140 d namic range
Note : in order to check the proper functioning of the measurement chain before launching a measurement, the screen
s stematicall displa s results each second. After the launching, these results will be displa ed at the rate of the logging
time.
8.1. Measurement in progress: audio recording on threshold
During data processing of a measurement and after visualization of temporal evolution with LDS23 or LDS300 software,
some results can be surprising and stir up questions:
•Is the obtained value come from a measurement artefact ?
•What is the sound source at the origin of this level ?
To help ou, DS200 instrument is equipped with an “audio recording” function that is automaticall activated for a
threshold exceeding previousl set.
This detection threshold concerns:
•the A-weighted equivalent continuous level on a duration of elementar integration of 1 second: LAeq 1s
OR
•the C or Z weighted maximum peak pressure level (according to the set weighting: usuall C): LCpk
•the recording principle after detection threshold suggests that sound source at the origin of this threshold exceeding
can not be active an more after the detection. As a consequence, DS200 performs s stematicall a sliding
recording of duration Tgl (4 s) preserved after threshold detection.
•the recording continues on the total duration of threshold and after threshold underflow, it goes on the same Tgl
duration previousl used.
•this method allows an “audio recording” of the sound source at the origin of the threshold and makes easier its
identification.
14

As it is ah help for recognition of sound sources at to optimize hardware resources, the audio recording format, the SD card
is defined as follows:
•accurac : 16 bits
•sampling: 12 kHz
DS200 instrument having a wide measurement d namic, 100dB, it is likel that the re-listening with a computer do not
allows an eas identification according to selected detection threshold.
To optimize the listening, the audio recorder incorporates an adjustable digital gain from 24 to 48dB with a step of 6dB.
This adjustment has no incidence on the measurement and interferes on audio files onl .
So, according to measurement conditions selection criteria, this adjustment allows to adjust the reduced d namic of audio
listening (computer + ear + environment = about 50 dB) to this more extensive of DS200 instrument (100dB).
Important: To make more comfortable the re-listening on PC, we advise the use of an external amplified speaker s stem to
the PC.
8.1.1. Temporal synoptic
VERY IMPORTANT: when audio function is activated, the DI duration of elementar integration for calculation of
the LAeq et LCeq equivalent continuous level is automaticall set at 1 second.

8.1.2. Synoptic of the management of the recording dynamic
Selection of a detection level for audio recording: it must be on the planned measuring range: 40-120 or 60-140 in two-
channel operating V1 and V2 or 40-140 in one-channel operating V1.
Example: do not choose a 125 dB threshold on the 40-120 range !!!
Setting of the digital gain for audio recording: recorder d namic is set in factor at 30dB.
This means that the recorder has 30dB in storage in peak pressure value be ond the selected detection threshold in LAeq
or LCpk.
Example: detection level = LAeq 1s: 105 dBA
Sound sources higher to this threshold are recorded without distortion if and onl if the maximum peak level does not
exceed: 105+30 = 135dB peak.
In general, sound sources have some high peak factors, prett much from 20 to 30 dB. That's wh it
is not possible to set the gain at a value lower than 24 dB. However, in situations where sound
sources are elaborated with peak factors ver high, it is possible to choose the digital gain be ond 30
db between 36 42 and 48 dB.
During programming, DS300 instrument displa s, according to selected criterion (reference threshold
and digital gain), the minimum and maximum peak pressure levels recordable properl .
Listening comfort:
It is recommended to keep the factor setting which is 30 dB. Eventuall , after experiences on site, it is possible to bring to
24dB.
In this case, the re-listening allows a correct identification for the 4 seconds before and after scheduled threshold
exceeding.
8.1.3. Use of audio recording
➢From MENU screen, select « Progr.mesure » with 1 and 2 ke s.
➢Validate with 3 key.
➢Press 1 ke to move the cursor until Audio element.
➢Select YES in reverse video pressing 2 or 3 ke .

Measurement in progress:
Different recordings are performed automaticall without intervention and without affect metrological calculations. Total
recording time available being limited, be selective to select the detection threshold value in order to not use too quickl
memor space and get repetitive and insignificant recordings.
Audio files:
All recordings are linked to the corresponding metrological file and saved as *.wav audio format on the micro SD card.
During data transfer on a PC, LDS300 software processes all the files and the re-listening of files to help about sound
sources recognition.
Memory space:
Available memor on micro SD card is divided into 2 areas: 1st one contains the metrological files and the 2nd one contains
audio files for re-listening.
Before starting a new measurement, it is advisable to check the remaining measurement capacit expressed in number of
event timers and batter capacit .
For that, from MENU screen:
➢Select with 1 or 2 ke Autonomy item.
➢Validate with 3 ke .
➢Check number of event timers and batter capacit .
Ex: 96 event timers and 14H00
In case of insufficienc , all data in the micro SD card must be deleted:
•with ke pad
•with LDS23 or LDS300 software.
WARNING:
Tell the person wearing the instrument that “Audio recording” function is activated.
Onl the person in charge of the measurement has the responsibilit to process recordings.

8.2.1. Immediate mode
➢Press 2 key.
Measurement starts immediately, results are displayed at the rate of integration duration.
8.2.2. Delayed mode
It is possible to set start and end of measurement (date-time) in case of absence.
For example : preparation of the instrument the da before the stud of night-work.
➢Press 3 key
Programming screen is displayed.
➢Move the cursor with 1 key (arrow).
➢Change the different item with 2 and 3 keys :
•Db : date of measurement beginning
•Hb : time of measurement beginning
•De : date of measurement end
•He : time of measurement end
➢Keep the item Repet at 01.
➢Move the cursor until Val pictogram appears.
➢Press 3 key linked to this pictogram.
Programming of measurement launching is performed.
The last two lines specifies :
•that memor capacit is sufficient : OK
•that batter capacit allows the measurement : OK.
In case of incompatibilit , KO is displa ed for OK. In this case :
•Erase memor of the instrument.
•Load the batter .
Important note : b using the dela ed mode without programming beginning date and time (current date and time alwa s
present) but b programming end date and time, measurement launches immediatel when it is validated and will stop at
the programmed time. This programming allows a measurement and instrument stop without being present.
8.2.3. Repetiti e delayed mode
As previousl , it is possible to set measurement end and beginning at moments (date-time) in case of absence and
according to an established period.
For example : following of a weekl noise exposure in case of night-work
Principle : set the start and end dates of the first measurement then indicate the number of
measurements to perform the following da s at the same time.
➢Move the cursor with 1 key (arrow).
➢Set date and time of first measurement starting and end.
➢Modif the item Repet : 01 indicating the required number of repetitive measurements from 02
to 05.

➢Move the cursor until OK pictogram appears.
➢Press 3 key linked to this pictogram.
Programming of measurement launching is performed.
The last two lines specifies :
•that memor capacit is sufficient : OK
•that batter capacit allows the measurement : OK.
In case of incompatibilit , KO is displa ed for OK. In this case :
•Erase memor of the instrument.
•Load the batter .
Note : about batter loading, KO will be displa ed if and onl if the residual capacit does not allow to perform the first
measurement. You must load the batter before an launching of measurements and complete the loading after 3 sessions
of 8 to 10 hours of measurement.
8.2.4. Delayed – Measurement wait
The principle of a dela ed or free repetitive dela ed measurement imposes a temporal management of the instrument
which is as follows :
•programming is validated.
•waiting mode is displa ed. This screen is displa ed a few moment then turns off. It reactivates itself a few moment
before the measurement.
•measurement is performed, data are recorded, The instrument moves to sleep mode until next measurement and
so on.
Important : it is possible at an time to stop sleep or waiting mode to launch the measurement.
➢In waiting mode, press 2 key.
The measurement starts immediately.
➢In sleep mode, between 2 measurements, press 6 ke (On/Off).
The waiting screen is displayed.
➢Press 2 key to start the measurement.
In all cases, onl measurement launching is modified, end programming and dail repetitive programming are the same as
the ones initiall .
8.3. During measurement
The individual exposimeter is an instrument carried out b a person exposed to noise nuisance. Usuall , the reading of the
results is made at the end of the measurement. In case of control during the measurement, partial results are available.
From starting screen :
➢Press 3 key to scroll through the three screns :
•E1 : general measurement screen : LCpK max, LAeq, LCeq on the DI logging time, LAeq,T, LCeq on T
measurement duration
•E2 : results screen : LCpk max on T measurement duration, LAeq,T, LCeq on T measurement duration, EA
sound exposure on the measurement duration
•E3 : screen of overload detection and peak level values (135 dB-137 dB and 140 dB)
•E4 : screen of measurement setting
➢Press 4 key to back to general measurement screen

8.4. top the measurement and the instrument
If the measurement is manuall launched, a manuall stop shall be performed from the general measurement screen.
➢Press 2 key.
The screen of Authorization number is displayed to confirm the measurement stop.
➢Move the cursor on the figures number 0000 in the middle of the screen.
➢Select the figures with 2 and 3 key.
➢Move the cursor on STOP arrow after the last figure.
The measurement stops and the screen allowing to erase or store the session appears.
The authorization number is 0082.
To turn off the instrument : press a few second the 6 ke until the screen shutdown.
Note : a fast press on this ke turn on or off the backlight.
8.5. Data processing
At the end of the measurement, it is possible to :
•Store data and create a session
•Reject the measurement and erase data
8.5.1. Accept data and store them
➢Press once 3 key (Sto).
A banner displays the storage phase.
