About This Manual

Instruction Manual for Hand-held Analyzer Types 2250, 2250-L and 2270, together with the user manuals, has been created to fulfil the documentation requirements of the National and International Standards that

the hand-held analyzers conform to. These standards are listed in section 4.2.

The user manuals provide all information necessary for operating Hand-held Analyzer Types 2250,

2250-L and 2270 and general advice on proper measurement practices.

This manual provides the remainder of the required documentation, including the full specifications required for conformance testing of the products when the hand-held analyzer is configured with

Microphone Type 4189. For other microphone configurations, there are a number of supplements to this manual that give the relevant information for those configurations.

The specifications in this manual and the supplements cover Hand-held Analyzer Types 2250, 2250-L and

2270 and all the software modules that have sound level meter- or octave-based frequency analysis capabilities. The specific subset of specifications for a given hand-held analyzer configured with a given microphone and software configuration can be found from the descriptions in the user manuals. Not all possible configurations are supported.

The relevant user manuals are:

• BE 1713: Hand-held Analyzer Types 2250 and 2270

• BE 1766: 2250 Light

• BE 1799: Building Acoustics Software BZ-7228

The user manuals also contain a summation of the most relevant technical specifications needed for the use of the instrument. In the event of any unintended inconsistency between the user manuals and the instruction manual, the instruction manual takes precedence.

Appendix B of this manual provides cross-references between specific paragraphs in the standards that require topics to be documented and the corresponding sections in this manual and the user manuals that conform to them.

1.2

System Overview

1.2.1

Analyzers

This manual covers:

• Hand-held Analyzer Type 2250: A single-channel general-purpose hand-held analyzer

• Hand-held Analyzer Type 2250-L, also called 2250 Light: A low-cost single-channel general-purpose hand-held analyzer

• Hand-held Analyzer Type 2270: A dual-channel high-end hand-held analyzer

Hand-held Analyzer Types 2250, 2250-L and 2270 – Instruction Manual

Types 2250 and 2250-L can, with the appropriate software modules, be used as a single-channel, single-range sound level meter and frequency analyzer. The self-generated noise and level range specifications are found in Chapter 4's figures the tables under Single range.

Type 2270 hardware can be utilised in two ways:

1) As a single-channel, single-range sound level meter and frequency analyzer like Types 2250 and

2250-L. In this case only a single channel can be measured at a time. The input is selectable between the two physical channels in the user interface and the full level measuring range is covered in a single range without a level range control. In the specifications this range is called Single range.

2) As a dual-channel, multi-range sound level meter and frequency analyzer. In this case both channels can be measured simultaneously. The full level measuring range is covered in two ranges with a level range control. In the specifications theses ranges are called High range for the least sensitive range, and Low range for the most sensitive range.

Information on how the individual software modules use the hardware, the selection of the input for single-channel measurements and the use of the level range control for dual-channel measurements can be found in the user manuals.

1.2.2

Software Modules

The hand-held analyzers are based on a unique platform concept that allows the user to choose different combinations of software applications and options. These applications and options can be purchased when needed and are delivered as easily installed licenses that open the relevant parts of the embedded software in the analyzer. Depending on the hand-held analyzer (Type 2250, 2250-L or 2270), different combinations of applications and options can be chosen.

All software modules that have sound level meter- or octave-based frequency analysis capability are based on the same basic sound level meter and frequency analyzer. The only differences are the number of measured quantities and the frequency range made available to the user. The specific subsets available in the individual software modules can be found in the user manuals.

Hardware and Software on the Analyzer

The About screen lists the hardware and software versions currently installed (click

in the Shortcut Bar at the bottom of the display screen, and select About).

1.2.3

Basic PC Software

Measurement Partner Suite BZ-5503 can be used for transferring basic measurement results and setups between the analyzer and a standard PC. It is also used for maintaining the embedded software in the hand-held analyzers.

Measurement Partner Suite is included on Environmental Software DVD BZ-5298.

For instructions on this software, see the software’s online help.

1.2.4

Hardware Setup

This section provides an overview of the hardware components used with the analyzers.

A hardware overview is provided in Fig.1.1, optional accessories are designated on the diagram.

The components needed for conformance testing Hand-held Analyzer Types 2250, 2250-L and 2270 are

listed in Table 1.1.

For some of the components in Table 1.1 the analyzers also conform to the standards listed in section 4.2

when using the following alternative components:

• As an alternative to Windscreen UA-1650, Windscreen UA-0237 can be used: It has the same acoustical behaviour but has no auto detection capability

Fig.1.1

• As an alternative to Microphone Extension Cable AO-0697-D-100, Microphone Extension Cable

AO-0441-D-100 can be used: It is the same cable but the plugs are physically shorter

• As an alternative to Mains Power Supply ZG-0426, the analyzer's power can be supplied by Mains

Power Supply ZG-0429, Utility Unit ZH-0689 or Power Panel ZH-0685 with Charger ZG-0857. If

Utility Unit ZH-0689 is used, Fig. 1.2 and Table 1.2 show the additional components and their connections. If Power Panel ZH-0685 is used, Fig. 1.3 and Table 1.3 show the additional components and their connections. In both cases the microphone preamplifier can only be connected to the analyzer through a microphone extension cable.

Information Required by the Standards

2.1

Introduction

This chapter contains the detailed information required by the standards to be described in the Instruction

Manual.

2.2

Mounting and Placing the Microphone

The microphone and preamplifier assembly can either be mounted directly onto the analyzer or connected via a microphone extension cable.

• When mounting the microphone and preamplifier assembly directly onto the analyzer, it is recommended to place the analyzer on Tripod UA-0587. Use the Tripod Extension for Hand-held

Analyzer UA-1651 screwed into the Tripod Mounting Thread situated on the underside of the analyzer, at the back

• When using a microphone extension cable it is recommended to mount the microphone and preamplifier assembly in Microphone Holder UA-1317 and then attach this to one of the tripods UA-0587 or UA-0801

When two microphones are needed for Type 2270, the Dual, 10-pole Adaptor (JP-1041) and two microphone extension cables can be used.

The microphone must be placed away from shielding, reflecting, or absorbing objects. In a diffuse sound field, absorbing objects will reduce the measured sound levels. In a free sound field, reflecting objects can change the measured sound levels. Typically, the sound level 0.5 m from a plain reflecting wall is 3 dB higher than if there was no wall.

The operator of the system may be personally shielding, absorbing, and reflecting, and the operator can also be an additional noise source.

The optimum position for the microphone is best found by trying different positions and observing the resulting sound levels.

2.3

Mounting the Analyzer on a Tripod

In order to minimise the influence of a tripod on measurements, the analyzer must be mounted on Small

Tripod UA-0801, or Tripod UA-0587, with Tripod Extension for Hand-held Analyzer UA-1651, as described in Chapter 2 of User Manual BE 1713 for Type 2250/2270 and User Manual BE 1766 for

Type 2250-L. The column of the tripod must be extended as much as possible above the base of the tripod.

For all practical purposes, the analyzer fulfils the requirements of IEC 61672–1 in this configuration, with or without Windscreen UA-1650 fitted. However, tripod mounting still presents some major difficulties in the measurement of acoustical characteristics of sound level meters and it is, therefore, normally beyond the scope of Type approval for sound level meters.

2.4

Calibration

The procedures for calibrating the analyzers can be found in User Manual BE 1713 for Type 2250/2270 and User Manual BE 1766 for Type 2250-L.

The calibration procedure, which is necessary for the electrical tests during conformance testing, can be

found in Section 3.5.

While performing the calibration procedures, the analyzer is automatically checked for its ability to perform the measurements.

For acoustic calibration, a Sound Level Calibrator with a calibration frequency of 1 kHz and a calibration level of approximately 94 dB is needed. It has to conform to the class 1 specifications of the International

Standard IEC 60942, Electroacoustics – Sound Calibrators.

It is strongly recommended that Brüel & Kjær Sound Calibrator Type 4231 is used.

2.5

Accessories and Sound Fields

The acoustical frequency response and calibration depends on the sound field, the microphone, the microphone accessories used and the electrical frequency response. To improve the quality of the measurement and help the user to measure correctly the analyzer compensates for the sound field, the microphone and the microphone accessories used by automatically changing the electrical frequency response and calibration.

This means that a calibration of a microphone is valid for both free field and diffuse field and for all the recommended accessories.

This also means that it is very important that parameters on the Setup screen reflects the desired configuration. The important parameters are:

Setup screen: Input parameters: Input, Transd. Used, Sound Field Correction, Windscreen Auto Detect and Windscreen Correction

Setup screen: Frequency Settings parameters: Low Frequency Option, Low Frequency, Broadband (excl.

Peak), Broadband Peak and Spectrum

2.6

Measuring Low-level Sounds

If the measured sound level is within the Linear Operating Range or, for C-weighted peak sound levels,

within the Peak C Range given in the specifications (see Section 4.9.7 and Section 4.9.8), then the self-

generated noise and level linearity problems can be ignored.

It is possible to correct the measured sound levels, except peak levels, for the typical self-generated noise,

found in the specifications, see Section 4.8.2. The correction for self-generated noise can be made by

subtracting self-generated noise, L inh

, from the total sound level, L tot

, using the following equation:

L

res

=

L

tot

)

If L tot

L inh

is less than 3 dB, the sound level is too low to be compensated.

Fig.2.1 shows the error on the measured sound levels from the presence of self-generated noise. The curve

can also be used for compensation by subtracting the error from the measured sound levels. This is equivalent to using the formula.

2.7

Measuring at Low Static Pressure

The frequency response of the microphone depends on the static pressure. Using a sound level calibrator to adjust the sensitivity of a sound level meter at the calibration check frequency provides no information on the influence of static pressure on frequency response. Conformance to the specified standards ensures that the system measures within the standard’s tolerances, in the range from 85 kPa to 108 kPa. Data for the frequency response as a function of static pressure for the microphone can be found in the Microphone

Handbook BA 5105.

At the calibration check frequency, both the microphones and the recommended Brüel & Kjær Sound

Calibrator Type 4231 are rather insensitive to variations in the static pressure – for Sound Calibrator

Type 4231, below 0.001 dB/kPa.

2.8

Frequency Weightings

Both broadband and spectrum measurements can be frequency weighted with A-, B-, C- or Z-weighting.

The A- and C-weightings conform to the requirements in IEC 61672–1 and IEC 60651. The B-weighting is not defined in IEC 61672–1, but conforms to the requirements in IEC 60651.

The Z-weighting (Zero frequency weighting) is a linear, unweighted frequency weighting. It conforms to the Z-weighting defined in IEC 61672–1 and the Lin response defined in IEC 60651.

Table 2.1 states the design goal frequency responses for the frequency weightings. They are stated for the

complete instrument including the microphone. The corresponding tolerance limits can be found in the standards.

Measured Quantities

This section gives a precise mathematical definition of the measured quantities and defines the abbreviations used on the display.

2.9.1

Instantaneous Broadband Measurements

These measurements are done continuously, independent of measurement Start, Pause and Stop. They cannot be saved and are only displayed.

Overload

For Instantaneous Measurements, the Overload indication is displayed as long as the overload condition exists, or for 1 s, whichever is the greater.

Overload is indicated as Overload on the screen and by a flashing red “traffic light” indicator.

Overload is common to all results of Instantaneous Measurements.

Under-range

The Underrange indication is displayed as long as the under-range condition exists, or for 1 s, whichever is the greater.

The Underrange condition is present if any measurement of time-weighted sound level, time average sound level, or sound exposure level is less than the specified lower limit of a linear operating range.

Time-weighted Sound Level, F and S Time-weighted

The time-weighted sound level, L xy

(t), is defined as twenty times the logarithm to the base ten of the ratio of a given root-mean-square sound pressure to the reference sound pressure, root-mean-square sound pressure being obtained with a frequency weighting, x, and standard time weighting, y, where:

The Taktmaximalpegel is, in other words, updated every 5 seconds and is expressed in decibels (dB).

The Taktmaximalpegel is not displayed by the analyzer. It is only used for the calculation of Taktmaximal-

Mittelungspegel.

2.9.2

Timed Broadband Measurements

These measurements are only executed when Start is activated and are paused when Pause is activated or when Preset Time has expired, whichever occurs first. The time interval between start and pause is the

Elapsed Time. During the measurement time interval, intermediate results are displayed as if the measurements were paused at the time of display. When the measurements are paused, the set of results, including Latched Overload and Overload %, are stored under Current Measurement and this is held until either Reset is activated or a new set of measurements are started. The Current Measurement (if any) is displayed and can be saved, together with setup and calibration information, to a project.

At the start of a timed measurement all time-weighted sound levels are reset to zero (–∞ dB). From this, they increase to their current values. The timed measurements derived from time-weighted sound levels

(e.g., Minimum Time-weighted Sound Level, Maximum Time-weighted Sound Level, Equivalent

Continuous I-weighted Sound Level, Taktmaximal-Mittelungspegel, and Statistics) are fist valid after this has settled. Therefore, the first value is measured and displayed after a delay from the start of the measurement depending on the present exponential averaging time. Measurement of Overload Percentage,

Equivalent Continuous Sound Level, Sound Exposure Level, and Peak Sound Level starts without delay.

Latched Overload

For the timed measurements, a latched Overload indication is displayed and included in the set of results if the overload condition exists at any time during the measurement time interval. The latched Overload is indicated by a red triangle on the screen. The latched Overload is common to all the results of the timed measurements.

Overload Percentage

The Overload Percentage, Overload %, is defined as the percentage of time within a time interval starting at t = T and ending at t = T +

Δt where the overload condition exists, where:

• T is the start time of the measurement, indicated as Start Time

Δt is the measuring period, indicated as Elapsed Time

The symbol used by the analyzer for Overload Percentage is: Overload

Statistics

Statistics can be based on sampling the continuous output of the exponential detectors F or S every 10 ms or the 1 s linearly averaged results L

. The samples are divided into 0.2 dB classes in which the frequency of appearance is counted. Based on the counted frequency distribution the percentile sound levels (also called the exceedance levels) L

are calculated.

• x is A for A-weighted or B for B-weighted

• y is F for Fast-weighted or S for Slow-weighted and nothing for L

eq

• N is a percentage between 0.1 and 99.9. It notes the percentage of time that the indicated noise level was exceeded during the measurement period.

2.9.3

Spectrum Measurements

Note: These measurements require Frequency Analysis Software to be enabled.

The definition of the measured quantities is the same as for the broadband measurements.

At low frequency bands the exponential time constants for Fast and Slow weighting are modified to get a

reasonable B*T product, see Section 4.11.5.

Timed Spectrum Measurements are delayed according to the same rules as Timed Broadband

Measurements (Section 2.9.2). As stated above, the exponential time constant is modified at low

frequencies. This leads to very long delays at very low frequencies.

Latched Overload and Overload Percentage is common to the broadband measurements.

Statistics

Statistics can be based on sampling the continuous output of the exponential detectors F or S every

100 ms. At frequencies below 12.5 Hz the sampling time is doubled for every octave the frequency is reduced. The samples are divided into 1.0 dB classes in which the frequency of appearance is counted.

Based on the counted frequency distribution the percentile sound levels (also called the exceedance levels)

L xyN

are calculated.

x is A for A-weighted, B for B-weighted, C for C-weighted or Z for Z-weighted

y is F for Fast-weighted or S for Slow-weighted

N is a percentage between 0.1 and 99.9. It notes the percentage of time that the indicated noise level was exceeded during the measurement period.

2.10

Ranges, Overload and Underrange

2.10.1

Single Range/Multi-range

Types 2250 and 2250-L can only be used as single-channel, single-range sound level meters and frequency analyzers. The range is called Single-range.

Type 2270 hardware can be used in two ways:

1) As a single-channel, single-range sound level meter and frequency analyzer like Types 2250 and

2250-L. In this case, only a single channel can be measured at a time. The input is selectable between the two physical channels in the user interface and the full level measuring range is covered in a single range without a level range control. This range is called Single-range.

2) As a dual-channel, multi-range sound level meter and frequency analyzer. In this case, both channels can be measured simultaneously. The full level measuring range is covered in two ranges with a level range control. Theses ranges are called High range for the least sensitive range, and Low range for the most sensitive range. Hand-held Analyzer Types 2250 and 2270 – User Manual (BE 1713) describes how to select the range setting.

2.10.2

Overload

Overload indicates that the input signal level exceed the capability of the analyzer with the current settings.

During measurement, overload is indicated as Overload on the screen with the icon and by a flashing red “traffic light” indicator. The indication is displayed as long as the overload condition exists or for

1 second, whichever is the greater.

22

Hand-held Analyzer Types 2250, 2250-L and 2270Instruction Manual

The final result of the measurement contains both an indication if there have been any overloads at all during the measurement and an Overload% that indicates the percentage of the measurement time that contained overloads.

If an overload condition exists, some of the input signal is clipped away and therefore missing in the broadband results, which becomes too small. In the spectrum measurements, due to the distortion of the signal, some of the missing signal is placed in other bands.

The Overload% is intended as a tool to help the user to assess whether he will use a measurement that contains overloads or not. Small percentages will only have a limited influence on the final results.

2.10.3

Underrange

Underrange indicates that one or more of the measured quantities time-weighted sound level, time average sound level, or sound exposure level is momentary below the specified lower limit of the Linear Operating

Range. Separate indications for each of the two selectable frequency weightings for these quantities. The decision of whether there is an underrange condition is taken and displayed every 1 second and is based on the results for the last 1 second.

Underrange is only indicated on the screen during measurement and is displayed. No underrange information is saved with the final result of the measurement.

The underrange indication does not account for the influence of self-generated noise from the microphone because the specifications for the lower limit of the Linear Operating Range apply for measurements of electrical signals inserted into the preamplifier through the applicable input device. This makes the underrange indication a dubious indicator of the quality of the measurement especially on the more sensitive ranges.

Underrange is only intended as a tool to help the user to assess whether he should chose a more sensitive range if such exists.

2.10.4

Selecting the Optimum Level Range

This is only relevant for Type 2270 in dual-channel, multi-range mode; else, there is only one range.

If Type 2270 is in Low range and you get Overload warnings you can try to change to High range.

If Type 2270 is in High range and you get Underrange warnings you can try to change to Low range.

If none of these conditions occur, you should prefer Low range. It has the lowest self-generated noise.

High range is only chosen when you expect that there can be very high sound levels.

2.11

Mechanical Vibration

Mechanical vibration can affect indicated levels at low levels. Section 4.12.4 gives an indication of the

level of these errors.

The primary source to the vibration sensitivity is the microphone. It is most sensitive to vibrations coming from a direction perpendicular to the diaphragm.

To reduce this problem the analyzer and primary the microphone should be mounted isolated from the vibrations if measurements are taken at places where there are strong vibrations.

Chapter 3

Conformance Testing

3.1

Introduction

This chapter contains the information needed to conduct conformance testing according to the specified standards.

3.2

Mounting for Acoustical Tests

For acoustical tests, it is important that the test rig for mounting the microphone to be tested is designed to minimise the influence of reflections to a level that is comparatively smaller than the test parameter’s maximum Expanded Uncertainties of Measurement. This has to be demonstrated with a good, known laboratory microphone.

Various ways in which the different microphone assemblies can be mounted to the test rig are:

• The analyzer, with the microphone and Microphone Preamplifier ZC-0032, can be mounted using

Tripod Extension for Hand-held Analyzer UA-1651. The tripod extension stem is screwed into the

Tripod Mounting Thread situated on the underside of the analyzer, at the back. The thread on the other end of the stem is used to mount the assembly to the test rig

• The microphone, together with Microphone Preamplifier ZC-0032, can be mounted separately in the

½

″ Microphone Holder UA-1317. The Microphone Holder can be mounted using the tripod mount thread. To minimise the influence of reflections from the Microphone Holder, bend the holder part to an angle of 45° ± 15° from the straight position

• Outdoor Microphone Kit UA-1404 can be mounted using the tripod mount thread in the Mounting Ring

3.3

Periodic Testing of Acoustical Frequency Responses

Acoustical signal test of frequency response can be made with plane progressive waves in an anechoic facility. However, this is normally very time-consuming and difficult to do with sufficient accuracy. For the purpose of periodic testing, it is recommended that you use one of the following Brüel & Kjær products for acoustic frequency response tests:

• Multifunction Acoustic Calibrator Type 4226

• Electroacoustic Calibrator UA-0033

If the Multifunction Acoustic Calibrator is used, the calibrator must be set to its Calibration and Pressure sound field modes. The calibrator must be calibrated. Further details can be found in the Instruction

Manual for the Multifunction Acoustic Calibrator.

Acoustical signal test with Electrostatic Actuator UA-0033 should be made only by personnel that are educated in and familiar with the use of the actuator. The actuator should be operated with a DC voltage of approximately 800 V and an RMS AC voltage of approximately 100 V.

23

24

Hand-held Analyzer Types 2250, 2250-L and 2270 – Instruction Manual

Adjustment data, which must be applied to the sound levels displayed in response to the sound pressure produced by Multifunction Acoustic Calibrator Type 4226, or in response to simulation of sound pressure by Electrostatic Actuator UA-0033, in order to obtain the equivalent sound levels that would be displayed in response to plane progressive sinusoidal sound waves incident from the reference direction, are given in

Table A.49 and Table A.50.

3.4

Mounting for Mechanical Vibrations Tests

The analyzer is mounted on the shaker using the Tripod Mounting Thread situated centrally on the underside of the analyzer.

3.5

Electrical Substitute for Microphones

To obtain a BNC Type electrical input, replace the microphone with a WA0302-B, 15 pF, fitted with a

10–32 UNF to BNC adaptor, UA-0245.

This Electrical Substitute for Microphones has (together with the preamplifier) a nominal attenuation of

0.65 dB.

The electrical input obtained in this way has a maximum input level of ±15.24 V

and no damage will

All electrical inputs can be short-circuited when needed for test.

To calibrate the analyzer for the electrical conformances test with a calibration that corresponds to the calibration you would get if the analyzer were fitted with a microphone with the nominal Open Circuit

Sensitivity do the following:

1) On the Setup screen (Full tab):

• Set Input, Transd. Used to the microphone that you intend to substitute

• Set Input, Input to Top Socket

2) Calibrate the analyzer by typing in the nominal sensitivity as the Sensitivity on the Calibration screen. For Microphone Type 4189, the nominal sensitivity is the microphone’s Open Circuit

Sensitivity (50.00 mV/Pa), attenuated by the Microphone Preamplifier ZC-0032’s nominal attenuation

(0.25 dB), which equates to 48.58 mV/Pa. Do not press the Start Calibration button.

3) Connect an electrical sinusoidal signal with a frequency of 1 kHz to the Electrical Substitute for

Microphones and adjust the amplitude of this signal until LZF (or LCF) displays 94.00 dB in the

Calibration screen. This electrical amplitude is the 94.00 dB reference for the electrical tests. The amplitude will typically be 52.5 mV. This is due to the attenuation of the Electrical Substitute for

Microphones together with the preamplifier (nominally 0.65 dB).

3.6

Testing 1/1-octave-band and 1/3-octave-band Filters

Note: These measurements require Frequency Analysis Software to be enabled.

All tests according to IEC 61260 must be conducted with Setup screen:

EMC Test Procedures

3.7.1

Signal Sources for Immunity Test

Acoustical Source for Testing According to IEC 61672, IEC 60651 and IEC 60804

The acoustic signal, which is used during the Immunity test according to IEC 61672, IEC 60651 and

IEC 60804, is applied to the microphone through a ½

″ plastic hose (a normal water hose) – from a source outside the test area. In this way, the acoustic source is not affected by the RF or magnetic field. The source may be a normal entertainment earphone.

To prevent the acoustic source from being affected by acoustic noise in the surroundings, the following method can be used.

Insert an acoustic attenuator in the hose close to the microphone, so that the sound pressure within the greater part of the hose is held far above the surrounding sound level. The acoustic attenuator can easily be made from a short piece of metal tubing with an outer diameter of ½

″. Squeeze a piece of paper tissue into the tube, and compress it until the desired attenuation is obtained. Up to 40 to 60 dB of acoustic attenuation can be obtained.

Electrical Source for Testing According to IEC 61260

The short-circuit of the Input signal may be achieved by short-circuiting the electrical substitute for microphones mounted on the microphone preamplifier.

3.7.2

Reference Orientation

Fig.3.2 shows the reference orientation of the instrument body, including the preamplifier and microphone,

relative to the RF-emitter/receiver. This is common to both Emission and Immunity tests.

3.7.3

Securing of Cables During EMC Test

During test, any excessive cable is folded back on itself in an even number of figure eights, as indicated in

Fig.3.2. The microphone and preamplifier assembly is arranged approximately 25 cm above the analyzer.

The cable arrangement is common for both the Emission and Immunity tests.

3.7.4

Testing EMC According to IEC 60804

Both the exponential time-averaged detectors and the linear time-averaged detectors in the analyzer are digital, and their results are calculated based on the same samples. Therefore, the L will be equal to short L

xeq

values when measuring steady signal levels.

xF

measurement values

As a consequence, no special operating mode giving a short duration L

xeq

measurement is provided, and only one test has to be carried out when testing Immunity to RF signals according to both IEC 60651 and

IEC 60804.

3.7.5

Accessories Included in EMC Test

The following accessories are connected to the instrument during the EMC tests:

• The preamplifier is connected to the top socket of the analyzer using the extension cable

• Signal Cables AO-0440 are connected to all the triaxial LEMO sockets on the rear connector panel of the analyzer

• Earphones HT-0015 is connected to the Earphone socket

• Mains Power Supply ZG-0426 is connected to the 'Ext. Power' socket. If Utility Unit ZH-0689 or

Power Panel ZH-0685 is used as an alternative to ZG-0426 the alternative connections are shown in

Fig.1.2 and Fig.1.3

• USB Interface Cable:

– Before hardware version 4.0: USB Interface Cable AO-1476 is connected to the USB socket

– From hardware version 4.0: The USB Interface Cables AO-1494 and AO-0708 are connected to the two USB sockets

• LAN Interface Crossover Cable AO-1449-D-010 or LAN Interface Cable AO-1450 is connected to the LAN socket if the analyzer supports LAN interface

Detailed descriptions of the parts are given in Table 1.1.

4.6

Frequency Responses

The frequency responses are given in tabular form in Appendix A and in graphical form in this section.

The specifications for the Lin response defined in IEC 60651 are equivalent to those given here for the

Z-weighting.

The acoustical frequency response depends on the sound field, the microphone, the used microphone accessories and the electrical frequency response. To improve the quality of the measurement, the analyzer compensates for the sound field, the microphone and the used microphone accessories by changing the electrical frequency response. This means that it is very important that the Setup and

Transducer parameters reflect the desired configuration. The important parameters are:

Setup screen, Input parameters: Input, Transd. Used, Sound Field Correction, Windscreen Auto

Detect and Windscreen Correction

Setup screen, Frequency Settings parameters: Low Frequency Option, Low Frequency, Broadband

(excl. Peak), Broadband Peak and Spectrum

Transducer screen: Transd. used and Microphone Type

By setting the Microphone Type parameter to Unknown (on the Transducer screen for the transducer used), an uncompensated electrical frequency response is ensured.

CHAPTER 4

Limit curves are drawn on some of the frequency response graphs in the following sections. These curves represent the IEC 61672–1:2002 limits, reduced by the Maximum Expanded Uncertainties of

Measurement from Appendix A of IEC 61672–1:2002. The Maximum Expanded Uncertainties of

Measurement used here are the maximum uncertainties that a test organisation may have on its measurements when it performs conformance tests according to IEC 61672:2002.

IEC 61672-1:2013 deals with uncertainty of measurement differently than the 2002 version; therefore, the terminology around the limit curves is different. Seen from an IEC 61672–1:2013 perspective, the limit curves are the standard’s acceptance limits. The only difference is that the small glitch between 200 and

250 Hz in the curves is removed in the 2013 version of the standard.

The Expanded Uncertainties of Measurement in the tables are the two-sigma limits maintained in the

Brüel & Kjær production for the specific product. This means that the correct value lies in the range of the measured value plus/minus the Expanded Uncertainties of Measurement with a probability of 95%.

Note: This range is not related to the production spread. The range is for a specific typical unit. The factory acceptance tests at Brüel & Kjær ensure that the ranges for all units are within the IEC 61672–1 limits.

Electrical Frequency Responses

The uncompensated electrical frequency response for the different frequency weightings are given in

the appropriate tables of Table A.2 to Table A.9 in Appendix A.

The electrical frequency responses in Fig. 4.1 and Table A.1 are valid both for introduction of the

Diffuse-field Frequency Responses

The diffuse-field frequency responses (also called random-incidence frequency responses) with

Z frequency weighting are provided in Fig. 4.9 to Fig. 4.11 and Table A.7 to Table A.9.

The diffuse-field body influence of the analyzer is so small that the diffuse-field frequency responses are the same with and without the microphone preamplifier connected to the microphone extension cable.

Free-field Frequency Responses for Diffuse-field Calibrated Instruments

According to IEC 60651 and IEC 60804, the free-field frequency responses in the reference direction for

diffuse-field calibrated instruments must be specified. These responses are given in Table A.10.

4.7

Directional Responses

This section gives directional responses for plane progressive sinusoidal sound waves normalised to the response in the reference direction. Both influence of body and accessories, and the resulting directional responses are given as tables in Appendix A. Only the resulting directional responses are given here as graphs.

The sensitivity variation graphs show the absolute maximum difference between the sensitivities at any two sound incidence angles within the specified interval of angles. For example, at each frequency the value for ±30° is the difference between the highest and the lowest sensitivity found in a circular cone with an opening angle of 60°, the top at the position of the microphone and with the reference direction of incidence as the axis. Because the angle interval defines a three-dimensional geometric shape there is only one set of graphs with sensitivity variations, also where the directional response is shown for two planes.

The graphs show the maximum variation for the two measurement planes combined. The sensitivity variations are also given as tables in Appendix A.

Limit curves are drawn on the sensitivity variation graphs in the following sections. These curves represent the IEC 61672–1:2002 limits, reduced by the ‘Maximum Expanded Uncertainties of

Measurement’ from Appendix A of IEC 61672–1:2002. The ‘Maximum Expanded Uncertainties of

Measurement’ used here are the maximum uncertainties that a test organisation may have on its measurements when it performs conformance tests according to IEC 61672:2002.

IEC 61672-1:2013 deals with uncertainty of measurement differently than the 2002 version; therefore, the terminology around the limit curves is different. Seen from an IEC 61672–1:2013 perspective, the limit curves are the standard’s acceptance limits.

IEC 61672–1:2013 defines relative directional response in clause 3.17.

The relative directional response for a reference angle can be derived from the specified directional response by normalization with the values (in decibels) in the reference direction; i.e., for each frequency the value at the reference direction is subtracted from the values at all angles so that the resulting value in the reference direction is 0 dB.

IEC 61672–1:2013 requires information on the directivity index.

CHAPTER 4

Specifications

37

The directivity index definition in the standard is not very precise; therefore, we have chosen to use the definition in IEC 61183:1994 chapter 4 so that the directivity index in decibels equals the difference between the free-field response in the reference direction and the diffuse-field response without the analyzers electrical responses.

The directivity index for a specific microphone configuration can therefore be found by subtracting the

Acoustical Response column minus the Electrical Response column in the relevant diffuse-field table

(Table A.7 to Table A.9), from the Acoustical Response column minus the Electrical Response column in

the relevant free-field table (Table A.2 to Table A.6).

Measuring Ranges

The Upper Limit in the following sections is based on the guaranteed worst-case limit for the analyzer and the nominal Open Circuit Sensitivity of the microphone. The Overload Limit can, due to tolerances in the analyzer, be up to 1.5 dB higher than the worst-case limit, but tolerances specified in the International

Standards are maintained as long as no Overload is indicated.

The Lower Limit in the following sections is based on the guaranteed worst-case limit for the analyzer, the nominal open circuit sensitivity of the microphone, under Reference Environmental Conditions, Sound

Field Correction set to Free-field and no microphone accessories selected.

Maximum Sound Level

The maximum Sound Level that the Sound Level Meter can accommodate without causing damage to the

Sound Level Meter: 158 dB Peak.

Total Range

Total Range is defined as the difference between the Upper Limit on the least sensitive level range, and the lowest sound pressure level measurable on the most sensitive level range, which can be measured at 1 kHz within the most conservative tolerance limits, specified in the International Standards IEC 61672–1,

At low centre frequencies, the B*T product for time weightings becomes too small to give statistically reliable measurements. To overcome this, the Fast time constant (125 ms) and the Slow time constant

(1000 ms) are replaced by progressively longer time constants with decreasing centre frequencies (and

corresponding bandwidths). See Table 4.13 and Table 4.14.

Battery

Part No.: QB-0061 Rechargeable Li-Ion battery

Voltage: 3.7 V

Capacity: 5200 mAh nominal

Typical Operating Time: > 8 hours. However, if the instrument is used in low temperatures or there is extensive use of the display backlight, this may reduce the time.

Battery Cycle Life: >500 complete charge/discharge cycles.

Battery Indicator: Remaining battery capacity and expected working time may be read out in % and in time.

Battery Fuel Gauge: The battery is equipped with a built-in fuel gauge, which continuously measures and stores the actual battery capacity in the battery unit.

Charge Time: In instrument, typically 10 hours from empty at ambient temperatures below 30ºC. To protect the battery, charging will be terminated completely at ambient temperatures above 40ºC. At 30 to

40ºC charging time will be prolonged. With external charger ZG-0444 (optional accessory), typically

5 hours.

Note: It is not recommended to charge the battery at temperatures below 0ºC (32ºF) or over 50ºC (122ºF).

Doing this will reduce battery lifetime.

Periodic Testing of Acoustical Frequency Responses

This section gives the adjustment data that must be applied to sound levels displayed in response to the sound pressure produced by Multifunction Acoustic Calibrator Type 4226, or in response to simulation of sound pressure by Electrostatic Actuator UA-0033, in order to obtain the equivalent sound levels that would be displayed under reference environmental conditions in response to plane progressive sinusoidal

sound waves incident from the reference direction. See Table A.49 and Table A.50 to view the data.
