Block Diagram of the tool

The block diagram represents the main elements of the HD2030 vibration analyzer.

Measure channels

HD2030 has four input channels polarized with direct current at 25V. It is possible to connect accelerometers with an amplifying integrated electronics IEPE (or similar) type that needs a maximum current of 2mA. It’s possible to connect to the RIGHT input a tri-axial type accelerometer or up to three monoaxial accelerometers; to LEFT input it’s possible to connect a monoaxial type accelerometer.

The amplified electrical signal of the four channels is sent to the LINE output.

The instrument

The amplified signal of the four channels is converted into digital samples through as many 25-bit A/D converters and digitally elaborated by two DSP.

The weighted levels and the related spectra of each channel are then transferred from the DSP to the microprocessor that manages the display and the storage.

The microprocessor supervises all the instrument processes: the management of the calibration, the Flash memory and the memory card, the display, the keyboard and the serial multi-standard RS232C/USB interface.

How to connect the accelerometers to the analyzer

The following diagram illustrates the different parts necessary to connect the accelerometers to the HD2030. The left input is monoaxial, the right input is triaxial.

INTRODUCTION

The HD2030 is a portable vibration analyzer able to perform spectral and statistical analysis. The instrument can supply all the measurement parameters required by the current normative concerning the operators protection from the risk connected with the vibra-

tions and is able to measure in hand-arm and whole body modes. It is also possible to evaluate the annoyance on persons due to vibration in buildings.

The instrument has been designed mixing the easy to use concept with the maximum flexibility and the possibility to update the instrument with the evolving standards on vibrations. The firmware can be updated directly by the user through the supplied Noise Studio

software (basic version).

HD2030 analyzer can perform all measurements requested by technical standards concerning workers protection from the risk of mechanical vibrations exposure.

The HD2030 complies with the specifications of ISO 8041 (2005) and ISO 5349-1 (2001

- vibrations transmitted to the hand-arm system) and ISO 2631-1,2 and 4 (1997 – vibrations transmitted to the whole body).

The octave and third-octave filters comply with the class 1 specifications of IEC 61260.

The HD2030 is a vibration analyzer suitable for the following applications:

• Evaluation of the exposure of operators to the risk connected with the vibrations transmitted to the hand-arm system through vibrating tools or items subjected to vibrations or impacts;

• Evaluation of the operator exposure to the risk connected with vibrations transmitted to the whole body also through the use of movement or transportation ways;

• Evaluation of the operator exposure to the risk connected with vibrations transmitted to the whole body by buildings subjected to vibrations or impacts;

• Octave or third-octave bands spectral analysis;

• Statistical analysis with calculation of the percentile levels from L

1

to L

99

;

• Attenuation of vibrations and reclamations.

The HD2030 analyzer simultaneously acquires the acceleration value in 4 channels and calculates, in parallel for all channels, both the weighted acceleration values and the

octave or third-octave bands spectra. In addition to the instant and average acceleration values, the analyzer also elaborates peak levels, vibration dose (VDV) and crest factors.

The frequency weighting can be chosen freely according to the specific application.

The possibility to connect any type of accelerometer with integrated electronics (type

IEPE or compatible), both triaxial and monoaxial, ensures the maximum ease of use and reduces the possibility of making mistakes or taking measures affected by electromagnetic interference or noise. The acquisition of the acceleration in 4 channels allows, for example, to make objective evaluation of the vibrations transmitted by a transportation way through to the driving seat or to evaluate, during the design and the production verification, the effectiveness of damping introduced by the suspension and by the absorbent material of the seat itself.

A versatile data logging function stores, both in the 8MB internal memory and in the memory card (SD up to 2GB), multiple profiles and spectra. Moreover it is possible to add to the profiles the accelerometers signals recording directly the digital samples. When analyzing the memorized data, it is then possible to examine the signals provided by the accelerometers and calculate additional parameters or verify the absence of source of errors such as those due to the DC-shift phenomenon. Each recording can be associated with a vocal comment. Using the available audio channel, it is possible to record an audio signal up to one hour, as a further opportunity to document the measures.

The performed recordings can be reviewed using the provided "Memory Navigator" program of the HD2030 analyzer. The vocal comments associated with the recordings can be listened using the appropriate headphones output.

- 7 -

Simultaneously to the acquisition of the profiles, it is performed the octave or third-

octave bands real time spectral analysis. The vibration analyzer calculates the spectrum of the sound signal every second and integrates it linearly up to 99 hours. It is also possible to associate with the spectrum a frequency weighted measurement parameter whose value is calculated from the acceleration values of each octave or third-octave spectrum band. In addition to the acceleration values for each band of the spectrum, it is possible to display the speed or displacement value.

The choice to measure hand-arm (HA) or whole-body (WB and BV) modify the extension of the spectral analysis: while for the hand-arm measures the frequency range extends from

3.15Hz to 3.15kHz (from 4Hz to 2kHz octave band spectrum), for whole-body measurements the range of the central frequency is shifted towards low frequencies from 0.315Hz to 315Hz

(from 0.5Hz to 250Hz in octave bands) .

As statistical analyzer, the HD2030 calculates the probability distribution of a measurement parameter at choice and analyzes it in classes of 1dB. In addition to the chart of probability distribution, it is also supplied the graph with percentile levels from L

1

to L

99

.

The LINE type not weighted analog outputs allows to record, for subsequent analysis, the accelerometers signal on a tape or directly in a PC with an acquisition board.

The calibration can be done using the accelerometers calibration data or using a vibrations generator able to produce a known and stable acceleration. A reserved and protected area in the permanent memory is used to record the last 120 calibrations performed. The supplied Noise Studio interface software allows to control the instrument and accelerometers and to document the measurements by downloading automatically the register file of the instrument calibrations.

In order to easily carry out the different measurements on the field, in the HD2030 it is possible to store up to 10 customizable and editable setups, also using the Noise Studio software. A title is associated with each setup in order to easily choose the desired one.

Considering that in order to measure in every possible situation it is necessary to use different types of accelerometers, up to 9 different sensor configurations both for the right channel (triaxial) and for the left channel (monoaxial) can be selected based on the requirements. The sensors calibrations and configurations files are associated with the analyzer setups, so that, by choosing one of the stored setups, the sensors to be connected to the input channels are indicated and the last associated calibration values are automatically uploaded.

To simplify the reading of the data on the display, it is possible to disable one of the two inputs or the single measurement channel.

The check of the vibration analyzer functionality can be done directly by the user, in the field, thanks to a diagnostic program.

HD2030 can be completely controlled by a PC through the RS232 and USB serial interfaces, using an adequate communication protocol.

The Noise Studio interface software allows to download and display data stored in the instrument, to handle the files related to setups, calibrations and configurations. With the software it is possible to load in the analyzer up to 10 different setups, chosen among the available ones. The file related to calibrations is downloaded at every connection and it is saved together with the measurement data. The different sensors configurations can be programmed through the PC, both inserting manually the accelerometers data and also using the proper CD-ROM associated with the accelerometers that can be supplied by Delta Ohm together with the instrument.

DESCRIPTION OF DISPLAY MODES

The acceleration values and the calculations made by the HD2030 analyzer are presented in 5 different screens. The instrument analyzes simultaneously the acceleration signals on 4 axis associated with four measurement channels (CH1,…, CH4.). It is possible, in each screen, to choose the channel to display by simply pressing the CHN key.

When the instrument is switched on, it briefly shows the Delta Ohm logo and the program version. Then it is requested the selection of the configuration for the sensors connected to the two inputs: first the right triaxial input, than the left monoaxial one.

The possible screen modes are:

• VLM (Vibration Level Meter): divided into four screens with three measurement parameters each. The values displayed in numerical form are updated every second. o

VLM_1: 3 profiles of instant or integrated measurement parameters calculated on each of the four channels; o

VLM_2: 3 profiles of instant or integrated measurement parameters calculated on the vector built with the data of the first three channels (RIGHT input); o

VLM_3: 3 parameters integrated in all the measurement time and calculated on each of the four channels; o

VLM_4: 3 parameters integrated on all the measurement time and calculated on the vector built with the data of the first three channels (RIGHT input).

• PROFILE: graphical form profile of a chosen parameter, related to the acceleration on each channel calculated at programmable intervals from 1s to one hour. The last 100 values of the chosen parameter are visualized.

• SPECTRUM: graph of the octave or third-octave bands spectrum graphic, related to the acceleration on each channel. A wide band parameter, calculated from the measured spectra, is associated with the spectrum. In addition to the accelerations, it is possible to visualize the speeds or the displacements, making a single or double integration on the spectrum. The spectrum can be visualized in multi-spectrum mode (MLT: one spectrum per second) or in averaged spectrum (AVR) where the spectrum is linearly integrated in all the measurement time.

• PROBABILITY: graph of the probability distribution of the parameter visualized in the

PROFILE screen for each channel. The values are analyzed in classes of 1dB.

• PERCENTILES: graph of percentile levels related to the parameter visualized in the

PROFILE screen for each channel.

The transition from one screen to the next one can be made at any time by pressing the

MODE key. At start-up, after the selection of the inputs configuration, the instrument displays the VLM screen.

Some indications appear in all the modes, they are:

ƒ The indicator of the acquisition status,

ƒ The overload indicator,

ƒ The indicator of the remaining batteries charge.

STOP: the instrument does not perform any measurement.

H (HOLD): the calculation of the integrated measurements has come to the end of the integration interval or the HOLD key was pressed.

P (Print): the printing of the current data is running.

R (Replay): it appears (blinking) when the “MEMORY NAVIGATOR” program is used to display a file saved in the instrument memory.

Immediately to the right of the symbol indicating the acquisition mode, there is the symbol indicating the possible overload. An arrow pointing up indicates that the input level has exceeded the maximum level measurable, a down arrow indicates that the input level is below the minimum according to the selected gain.

The maximum measurable level in the different settings of the measurement range selector is indicated in the technical specifications (see the chapter "TECHNICAL

SPECIFICATIONS").

An internally empty arrow reminds that an overload occurred, while a full arrow indicates that the signal is currently exceeding the limit.

To the right of the overload indicator it is displayed the integration time Tint of the instrument, which is programmable from 1s to 99h. When the integration mode is set to

multiple, the "Tint" symbol in the VLM screen blinks. If Tint = 0, the integration is becomes continue.

In the upper right corner there is the battery symbol. The batteries discharge appears as a gradual emptying of the symbol. When the remaining working time of the instrument is about 10%, which is roughly correspondent to 30 minutes in the continuous acquisition, the battery symbol blinks. A protective device prevents the instrument from taking measurements with insufficient charge level and automatically shuts the instrument off when the charge level is reduced to a minimum.

The charge level of the batteries, expressed in percentage, is visible in the menu main screen, that can be accessed pressing the MENU key once. Press the MENU key again to return to the measurement screen.

For details, see the chapter "REPORTING OF LOW BATTERIES AND REPLACEMENT OF

BATTERIES."

Pressing the ENTER key, the parameters related to the visualized screen can be selected in sequence. While the selected parameter is blinking, it is possible to change it pressing the

UP and DOWN arrow keys. Pressing ENTER, or automatically after about 10s, the parameter is confirmed and the selection mode is exited.

In graphic visualization mode it is possible to change the parameters of the vertical scale using the UP, DOWN, LEFT and RIGHT arrow keys: the LEFT and RIGHT keys compress and expand the vertical scale respectively, the UP and DOWN keys decrease and increase the initial and final levels of the vertical scale; in this way the graphic is moved upwards and downwards respectively.

The VLM screens shows, in numerical form, three frequency weighted parameters related to each of the four measurement channels or to the acceleration vector calculated with the data of the first three channels. It is possible to scroll in sequence the screens using the

right and left cursor keys.

The horizontal bar visualizes the instant levels of the four measurement channels expressed in dB.

VLM_1 and VLM_2

The first two screens VLM_1 and VLM_2 present instant and integrated parameters that are acquired, and in case memorized, as a profile form with 1 second acquisition interval or integrated with intervals programmable from 10s to 1 hour. In the VLM_2 screen are visualized the parameters related to the channels of the vector acceleration sum (CHΣ) and maximum (CHM). The measurement parameters to be displayed can be set entering the menu Parameters >> Vibration Analyzer.

VLM_3 and VLM_4

The last two screens VLM_3 e VLM_4 present global parameters integrated in all the

measurement period. It is possible to automatically memorize the value of these parameters at the end of each measurement session. In the VLM_4 screen are visualized the parameters related to the channels of the vector acceleration sum (CHΣ) and maximum

(CHM). These measurement parameters can be set entering the menu Parameters

>> Data Logger >> Global.

To change the measurement unit without entering the instrument menu, it is suffi-

cient to use the RIGHT and LEFT arrow keys. The measurement units are dB, m/s 2 , cm/s 2 , ft/s 2 , in/s 2 , g. The measurement unit selected is unique and it is applied to all the visualized parameters.

The CHN key allows to change the visualized channel. The measurement channels of single axis acceleration are four (CH1,…, CH4) while the measurement channels of the vector acceleration are two: the “sum” vector (CHΣ) and the “maximum” vector (GHM), both calculated with the data of the first three measurement channels (RIGHT input).

The values can be visualized in dB or in m/s 2 .

The CHN key allows to change the visualized channel.

With the LEFT and RIGHT arrow keys it is possible to change the vertical scale of the graph while with the UP and DOWN arrow keys it is possible to choose the reference value of the vertical scale.

The spectral analysis is made both in multi-spectrum mode (MLT), where a spectrum every second is visualized, and in average spectrum mode (AVR), where the spectrum integrated in all the measurement time is visualized.

It’s possible to associate with the octave or third-octave bands spectrum, the value of the frequency weighted acceleration, calculated from the spectrum.

CURSORS OPERATION

It is possible to activate two cursors to read the value of the visualized bands. Pressing the CURSOR key once, the first cursor is activated, pressing the second time, the second cursor is activated while pressing the CURSOR key the third time, both cursors are activated in tracking mode. To place the cursors in the desired points, the arrow keys next to the CURSOR key can be used.

When the cursors function is not active, it is possible to pass from the visualization of the acceleration for each band to the speed or displacement visualization, pressing in sequence the left and right cursor keys.

Using the HOLD key, the graph updating is paused, simplifying the reading of the measured values. Press again the HOLD key to return to the real time visualization.

Keeping pressed the cursors activation key, the limit acceleration curve is

visualized. This curve is based on the acceleration value in the band selected with the cursor

L1 and presents for each band the limit value of the acceleration corresponding to a displacement equal to that of the selected band.

For example, it is possible to choose as reference band with the cursor L1 the band corresponding to the dominant frequency of the spectrum and, supposing that the displacement component at this frequency is also dominant, visualize the maximum acceleration levels on the other bands of the spectrum that cause displacement values equal to or lower than the one of the selected band. Eventual phenomena of DC-shift happen with acceleration values at low frequencies with unreal associated displacements and so can be easily localized because they

will be associated with values of acceleration at low frequencies greater than the visualized limit.

To disable the limit acceleration curve keep pressed the CURSOR key.

The visualized measurement parameters can be modified without entering the

menu of the instrument. Pressing the ENTER key while the instrument is in STOP mode, the directly changeable parameters can be scrolled in sequence. When the selected parameter blinks, it is possible to modify it using the UP and DOWN arrows.

The changeable parameters are:

• The integration interval (Menu >> Parameters >> Instrument >> Measure >> Integration Interval). It can be set from 1s to 99 hours (when it is set to 0, the integration is continuous)

• The frequency weighting of the acceleration value associated with the spectrum

(Menu >> Parameters >> Spectrum Analyzer >> Auxiliary weight). This parameter is changeable also in measuring mode.

• The type of the visualized spectrum MLT or AVR (Menu >> Parameters >> Spectrum Analyzer >> Mode). This parameter is changeable also in measuring mode.

APPLICATIONS

The HD2030 analyzer can measure vibrations in three different applications selectable with the parameter Menu >> Parameters >> Instrument >> Measurement >> Application:

• Hand Arm (HA) for the measurements of vibrations transmitted to the hand-arm system, for example by tools through the grip.

• Whole Body (WB) for the measurements of vibrations transmitted to the whole body, for example to a driver through the seat.

• Building Vibration (BV) for the measurement of vibrations transmitted to the whole body by buildings.

In general, different applications require specific accelerometers which differ mainly for the sensitivity, frequency response, weight and mounting characteristics.

The accelerometers suitable for the HD2030 may be triaxial or mono-axial type with integrated electronics (IEPE or equivalent) and sensitivity from 1 mV/g to 1V/g.

These accelerometers are current-supplied by the analyzer with a bias voltage of 25V and a maximum current equal to 2mA.

Since the dynamic range of the accelerometer- analyzer chain is limited to about 100dB, in order to perform all types of vibration measurements (hand-arm and whole body vibration or buildings), accelerometers with different sensitivities are required. In fact, while for the measurement of vibration transmitted to the hand-arm can be used an accelerometer with a sensitivity from 1 mV/g to 10 mV/g, capable of measuring peak accelerations up to

5000 ÷ 50000 m/s2 , for the measurement of accelerations in buildings it is necessary to use accelerometers with a sensitivity of 1 V/g, in order to measure accelerations starting from

1 mm/s2.

H AND A RM

Many tools operated or gripped by hands generate vibrations. In some of these tools the vibration levels can be very high: for example, saws, hammers, grinders, drills, cleaners, vibrating plates, mowers, hammers, etc.. The vibration is transmitted to the operator's hands

(and arms) through physical contact with the utensil. In some cases vibration is transmitted directly by gripping the part to be machined (such as on a column grinder).

The procedures for measuring and assessing exposure of workers to hand-arm vibration are defined by ISO 5349-1 and ISO 5349-2. For measurements are used accelerometers with a sensitivity from 1 mV/g to 10 mV/g , reduced size and weight, capable to measure weighted accelerations of about 1m/s than 10000 m/s 2

2 while, at the same time, very high peak accelerations even higher

. In most practical situations will be used a miniature triaxial accelerometer, with a sensitivity of 10mV/g and resonant frequency greater than 10kHz. When the peak accelerations exceed 1000g repeatedly, it is necessary to use a shock accelerometer with 1mV/g sensitivity and resonant frequency greater than 50kHz. In this case also a mono-axial accelerometer is enough, taking care to orientate it so as to measure the accelerations along the dominant axis. For exposure assessment should be considered vibrations being transmitted to the center of the operator's hand during the tool’s grip and use. Since normally it is not possible to fix the accelerometer in that position, while this would constitute an obstacle to the operator, the accelerometer is fixed at the closest position to the one occupied by the hand (so that it would not constitute a disturbance to the use of the machine itself). The picture shows the position in which, according to ISO 5349-2, the accelerometer is attached to the handle of hammers and chipping hammers. In some cases, for the particular shape of the handles or the overall dimensions of the control lever, it is not possible to fix the accelerometer in accordance with the standard’s guidance. In this case an alternate location in the closest possible location to the operator's hand will be found. The demolition hammers have two handles, one of which cannot be used to fix

- 19 -

the accelerometer because it’s entire length it occupied by the operating lever: the transducer must be necessarily mounted on the handle without the lever.

These pictures show the possibility to mount the sensor for two different handles categories. The

ISO standard 5349-1 specifies the orientation of the reference system according to which are to be collected the three acceleration’s vector components; nevertheless, for each specific category of portable machine tool, ISO 8662 gives the definition of the specific coordinates to be adopted.

The standard defines the coordinate system:

• Z direction: the direction parallel to percussion direction; in ISO 5349-1 this axis takes the direction of the third metacarpal bone of the operator’s hand;

• Y-direction: the direction in the plane including the handle and the Z axis; orthogonal with the Z axis.

• X -direction: direction perpendicular to

Y and Z directions.

Since the ISO 5349-1 introduced as evaluation parameter the accelerations vector sum, the orientation of the coordinate system, purely conventional, does not affect the evaluation procedure; it is therefore independent of the reference system adopted.

Selecting the application Menu >> Parameters >> Instrument >> Measurement >> Application: HA, the HD2030 analyzer performs measurements in accordance with ISO 5349. The weighted acceleration (to simulate the the hand-arm system sensitivity), is calculated applying the filter named Wh on all measurement axes. Alternatively are available the band-pass filters

Fz and Fc, respectively, 1 Hz ÷ 3.5 kHz and 6.3 Hz ÷ 1250 Hz and the analyzer measures the accelerometer’s signals spectrum by octave bands from 4Hz to 2 kHz or third octave from

3.15 Hz to 3.15 kHz.

In the vibrations transmitted to hand-arm system, transducer’s mounting is the most delicate operation. The accelerometer weight should be less than 10% the weight of the tool and typically less than 30g including the weight of the mounting adapter. The accelerometer must be fixed to the handle so as to follow the oscillations, therefore allowing acquisition of vibrations effectively transmitted to the operator's hand.

HD2030AC1

The HD2030AC1 is a compact cube adaptor that is fixed with a plastic or metal strip to the handle of the tool to analyze. The position must be chosen as close as possible to that occupied by the hand according to the indications of ISO 5349-2. Light alloy built, it is suitable for measurements on lightweight tools where it is necessary to contain the weight of the measuring system. It can be used with accelerometers with a threaded hole (10-32 UNF or UNC 5-40); the accelerometer is secured by a screw on the adapter. This support ensures easy and quick mounting and optimum adaptation to different types of handles.

The accelerometer, equipped with a threaded hole (10-32 UNF 5-40 or

UNC), is secured to the adapter via a tightening screw which, passing through a hole on the

- 20 -

upper surface of the adapter, is screwed to the accelerometer base. The vibrations produced by percussive machine tools movement, are characterized by very high frequency and intensity acceleration’s spectral components. With this loads, the piezoelectric crystal, which implements acceleration’s transduction into electrical signal, is subjected to stress and generates a continuous spurious signal very high for a long time, even after the physical load has ended; the spurious signal overlaps the detected signal adding distortion to the measurement.

To avoid this phenomenon, called "DC shift", it is necessary to reduce the accelerometer’s loads at higher frequencies. Normally, the presence of dumping material on the handle or the interposition of a thin rubber layer (1-2 mm) between the support of the accelerometer and the handle, are sufficient to prevent the phenomenon (1 in the picture). The resilient material must be compressed to the maximum tightening of the clamp mounting of the support. To avoid damaging the resilient material while tightening, it is sufficient to interpose a alloy ring with a thickness of 1-2 mm between such material and the clamp (2 in the picture). The vibrations transmitted from the tool to the hand-arm will be properly represented only under certain conditions by the measurement made by fixing the accelerometer to the handle as previously described. In fact, by the tightening of the adapter to the handle depends the fraction of vibrational energy transmitted to the sensor and therefore measured. It’s evident that tightening the clamp to the maximum will be obtained a high mechanical coupling and therefore the measured acceleration will be maximum. However, not always by tightening the clamp to the maximum, it will be achieved a representative measure of the true stress the operator's hand is subjected to. Normally the operator tightening the handle exerts a variable grip strength, depending on the particular processing step and in any case a compromise between operational effectiveness and comfort. To detect the vibrations really transmitted by the tool to the operator it is sometimes convenient to use supports with specific shapes to be interposed between the hand and the handle.

HD2030AC2

HD2030AC2 and HD2030AC3 adapters must be gripped between the hand and the handle. As the accelerometer is fixed in a lateral position, the measurement must be repeated by placing the accelerometer on both sides of the hand.

These adapters are suitable for large cylindrical handles coated with resilient material.

The HD2030AC3 is steel made and has to be used with accelerometers

The HD2030AC4 is an adapter to be held between the hand and the handle. The accelerometer is placed in central position between the middle finger and the ring finger or between the index and the middle fingers.

Light alloy made, it is suitable for anatomical shape, non-cylindrical and/or small dimension handles.

It must be uses with accelerometers fitted with a threaded hole (10-

32 UNF or UNC 5-40); accelerometer is secured by a screw on the adapter.

The spectral analysis is performed in the range 3.15Hz to 3150Hz. In the measurements of the vibrations transmitted to the hand-arm system, it is useful the visualization of the limit acceleration available in the SPEC-

TRUM screen.

In case of doubt, it is possible to enable the direct recording of the signal provided by the accelerometers (only with storage in memory card). The DC-shift phenomena can be easily detected analyzing the signal of the accelerometers with the Noise Studio software supplied.

W HOLE B ODY

The reference standard for assessing exposure to whole-body vibration is there-ISO

2631-1:1997. It defines standardized methods for measuring whole-body vibration and provides some guidelines for the assessment of health effects. The Vibration’s transmission can be through the feet of a person standing or sitting on a seat, through the buttocks and the back if the person is sitting, or through the support area for a person in a supine position.

The standard defines the coordinate systems for the measurement of acceleration; x, y and z axes are always directed in the same direction but with different origins, depending on the position of the operator is sitting, standing or lying down. In whole body vibrations the z axis, which is directed in the spinal column direction, is the higher risk organ to vibrations exposure.

The recorded magnitude is the r.m.s. weighted acceleration value (Root mean square value) in the frequency range from 0.5 Hz to 80 Hz. Below 0.5Hz the body, as a single mass, homogeneously follows the displacement of the vibrating surface with which it is in contact to. Higher frequencies than 80Hz involve only the surface of the body where the contact is; deeper layers of the epidermis leads to a rapid attenuation of vibrations not reaching internal structures of human body.

Procedures to measure and assess worker’s exposure to whole-body vibrations are defined in

ISO 2631-1 and ISO 2631-2. For whole body vibration measurement is used an accelerometer with a typical sensitivity of 100mV/g. The accelerometer may be fixed directly to the surface transmitting vibrations to the human body using a screw or using glue. Alternatively, if the surface is metallic, it is possible to fix the accelerometer using a magnetic support. The magnetic base can also be used for nonmagnetic surfaces; a metal disk can be glued to the surface, then the accelerometer (mounted on the magnetic base) fixed on it.

If the surface is not sufficiently planar, it is possible to use a mobile support where the accelerometer is fixed; the weight of the support must be sufficient to ensure acceleration measurement up to at least 1m/s 2 .

HD2030AC5

Support suitable for vibration measurements on floors and other surfaces.

Provides three different fixing points:

• in the hollow seat placed on the support’s lower face

• on the upper face with a threaded hole,

• on the adaptor cube fixed on upper face.

To access the hollow seat, unscrew the three screws used to close the back. The cavity has been sized for hosting a triaxial accelerometer with a central hole.

The accelerometer’s connecting cable passes through the side hole (see picture). To help analysis of acquired signals, we recommend that you reproduce, on the upper face, the same axial directions of the sensor.

On the upper face is present a threaded hole for mounting a triaxial or monoaxial accelerometer.

Usually the accelerometer’s sensitivity should be about 100 mV/g for working environment measurement and 1V/g for building vibrations annoyance measurements.

With the support is provided a cube adapter to be fixed on the upper face; this is for connection of three high sensitivity mono-axial accelerometers. To connect the three accelerometers to HD2030 analyzer is requested HD2030.CAB13 cable.

The support is provided with three support feet and a spirit level: if necessary, adjust the two mobile feet to adapt the horizontal position of the support using the spirit level as a reference.

To measure vibrations transmitted from seats and backs , the accelerometer is normally inserted in a rubber pad, made according to the requirements of EN 30326-1. This pad is positioned on the seat or fixed on the backrest with a tape so that is interposed between the seat itself and the body part submitted to vibrations.

Unlike the measurement of hand-arm vibrations, where the modulus of the acceleration vector is compared to the legal limits, to the extent of whole-body vibration it is the comparison with the dominant component, namely the one along the axis having the greatest strain. It’s therefore necessary to accurately orient the accelerometer’s axes according to the reference system established by ISO 2631-1 in order to avoid recalculating x, y and z acceleration components.

Selecting the Menu >> Parameters >> Instrument >> Measurements >> Application: WB, the

HD2030 analyzer performs measurements in accordance with ISO 2631-1.

The acceleration (frequency weighted to simulate the human body sensitivity to vibration) is calculated by applying the filters Wb, Wc, Wd, We, Wj, Wk to the measurement axes, as a function of the body’s part subjected to vibrations and the type of assessment needed: person’s health, comfort or perception. Alternatively are available Fz and Fa band-pass filters respectively 0.2 Hz ... 3.5 kHz and 0.4 Hz ... 100 Hz

The analyzer can calculate the accelerations spectra in octave bands from 1 Hz to 250 Hz or in third octave from 0.5 Hz to 315 Hz

B UILDING V IBRATION

With this application, the HD2030 analyzer performs the measures in accordance with

ISO 2631-2. For the evaluation of annoyance due to vibrations transmitted by the building structure, accelerometers are used with high sensitivity (typically from 1V/g) and resonance frequency greater than 1000Hz. The accelerometer is typically mounted on a heavy block to be placed on the floor, like HD2030AC5 (see description in the previous paragraph).

Selecting the Menu >> Parameters >> Instrument >> Measurements >> Application:

BV, the HD2030 analyzer performs the measurements according to ISO 2631-2.

The acceleration signal, weighted to simulate the human body sensitivity to vibration, is filtered with Wm weighting on all measurement axes. Alternatively Fz and Fm band-pass filters are available respectively 0.2 Hz ... 3.5 kHz and 0.8 Hz ... 100 Hz

The analyzer can calculate the accelerometer signal spectrum in octave bands from 1 Hz to 250 Hz or third octave from 0.5 Hz to 315 Hz

MEASUREMENT MODES

The HD2030 analyzer is able to measure in two different modes, selectable with the parameter Menu >> Parameters>> Instrument >> Measurement >> Integration Mode:

• Single Integration (SING) with measurement time programmable from 1s to 99 hours, and the possibility of manual stop.

• Multiple Integration (MULT) with manual stop of the measurement. The measurement time is divided in time intervals programmable from 10s to 1 hour.

The measurement starts pressing the START/STOP key.

At the beginning, the measurements are affected by the settling time of the accelerometers signals. To minimize the effect, after starting the measurement pressing the START/STOP key, the instrument keeps zeroed the instant and integrated parameters until it is elapsed the delay time, that can be set with the parameter "Menu>> Parameters>> Instrument >> Measurement >> Integration Delay", from a minimum of 1 second to a maximum of 99 seconds.

In this mode, the instrument calculates the integrated parameters, like the average time of acceleration for example, in the set measurement time Tint.

The measurement time is programmable from a minimum of 1 second to a maximum of

99 hours with the Menu>> Parameters>> Instrument >> Measurement >> Int. Integration.

It is possible to pause the measurement by pressing the PAUSE key, and restart the measurement by pressing the same key. While the instrument is paused it is possible to reset all the integrated parameters by pressing the START/STOP key.

The measurement ends automatically when the set integration time expiries, or manually by pressing the START/STOP key.

At the end of the measurement, the integrated parameters indicate the value calculated in all the measuring period, excluding the pause intervals.

The spectral analysis, if performed in AVERAGE mode (Menu>> Parameters>> spectrum analyzer>> Mode: AVERAGE), and the statistical analysis provide respectively the average spectrum, the probabilities and percentiles levels calculated in the measurement time.

USE OF THE EXTERNAL MEMORY CARD

The HD2030 has an interface that handles an external memory card for storing the data, the configuration parameters of the instrument and sensors.

The memory card, supplied with the instrument, has Delta Ohm code HD2030MC. If cards not supplied by Delta Ohm are used, make sure they have the same read / write speed performances.

The card must be SD-type with a maximum capacity of 2GB.

To use a new memory card, it is necessary:

1. to format it using the Noise Studio PC software.

2. to initialize it using the HD2030: the initialization function creates the folder where the measurement files will be placed and copy the calibration log file (see the description of the calibration program).

The formatting operation requires a PC equipped with a memory card reader (not supplied with the instrument). Normally all the latest laptop and desktop PC are provided with it.

If not, it is possible to use an external memory card reader connectable to a USB port.

To format a SD card, proceed as follows:

• If the PC is without reader, connect an external SD cards reader to a PC USB port.

• Start the Noise Studio software.

• Press the instrument management key in Noise Studio: press the Format Memory Card key.

• Select the path of the card to be formatted and press ENTER.

• In the next screen make sure it is selected the parameter "File System = FAT" and press

START: the card is formatted.

• When it appears the message "Formatting completed”, press OK to confirm and CLOSE to exit.

• Close the Noise Studio software.

• The formatting procedure is complete.

To initialize a card, proceed as follows:

Two methods are provided:

• Use of the "Initialization MC" function in the programs menu of the instrument (see the details in the description of the programs): this feature erases the eventual data already existing in the card.

• If the card is new and already formatted, turn on the instrument after inserting the card into the front slot of the instrument: the initialization procedure starts automatically. At the end of the operation, it appears the message "MC installed and ready to use."

S ENSORS C ONFIGURATION P ROGRAM

This program allows to configure the sensors that will be used for the measurements with the HD2030 analyzer.

It is possible to memorize up to 9 different sensors for the right input and 9 for the left input. The sensors related to the right input are triaxial type while the ones related to the left input are monoaxial type.

The parameters of the sensors are saved in a specific file in the internal memory of the analyzer and, if present, they are also saved in the Memory Card.

The requested parameters are:

• Manufacturer

• Model

• Serial Number

• Type: triaxial or monoaxial accelerometers for the right input and monoaxial for the left input.

• Nominal Sensitivity: Sensitivity nominal factor of the accelerometer (mV/g)

• Range: the maximum acceleration value measurable (g pk)

At startup the instrument load the file with the parameters of the sensors and it is requested to select a configuration for each of the two sensors. With the PREV. and NEXT. keys of the keypad it is possible to scroll the different sensors, and with the CURSOR key a sensor for each input can be selected.

The blinking warning “NO CAL” next to the nominal sensitivity value indicates that, for that sensor, the calibration data are missing: in this case the nominal sensitivity is used.

The same process is used when a complete setup is loaded (see the Setup Management program description): the instrument verifies the existence of the calibration file for the two accelerometers included in the selected setup. If the sensors have been calibrated, the sensitivity parameters are loaded automatically, otherwise it will be used the nominal sensitivity associated with the configuration.

Note: even if it is possible to operate directly on the instrument, the management of the sensors configuration can be more easily done with the PC software Noise Studio (see the details in the software manual).

To configure the sensors, proceed as follows:

• Connect the accelerometers to the appropriate inputs and switch on the instruments.

• Start the program pressing in sequence the keys: MENU >> Programs >> Sensors Config..

The value can be set from 3 (minimum) to 9 (maximum).

• Auto-Switching Off: the instrument has a function to switch itself off automatically after 5 minutes if the instrument is in STOP mode and no keys are pressed in this time interval. Before switching itself off, the instrument emits a series of warning beeps: press a key to avoid the switching off of the instrument.

• Language: it allows to choose the instrument’s menu language between Italian, English, French and Spanish.

Input/Output

Submenu for the choice of the parameters related to the inputs and outputs of the instrument.

• Type of print: it activates the printing of the measured levels and it allows to choose which data to print. When the parameter is set to OFF, the printing is disabled. In the other cases data are automatically printed when the measurement ends. The possible settings are: OFF indicates printing disabled, VLM for printing the numerical parameters visualized in the VLM screen, SPC for the printing of the octave or third-octave bands levels and VLM+SPC for printing both. See the chapter “CONNECTION TO A

PRINTER”.

• TRGOUT Source: the TRGOUT output, if activated with TRGOUT=RUN, switches from the pause level to the active level when the instrument enters the acquisition mode

(RUN). When the parameter is set to OFF, the TRGOUT output is deactivated.

• TRGOUT Polarity: the TRGOUT output can have a positive (POS) or negative (NEG) polarity, with low or high pause level respectively.

• RS232 Baud Rate: this parameter allows to select the data transfer speed for the

RS232serial connection from a minimum of 300 to a maximum of 115200 baud. A higher value indicates a faster communication, so, if there are no other contrary

indications, select the higher possible value to speed up the data transfer. If the instrument is connected to a printer with RS232 serial input or with serial/parallel converter, the value supplied by the printer manufacturer must be set.

WARNING: when the serial interface is used, the communication between the instrument and the PC (or device with serial input) works only if the Baud Rate

- 59 -

of the instrument and PC (or device) is the same. The supplied Noise Studio software sets automatically the serial port of the PC: on the instrument set

“RS232 Baud Rate = 115200”.

• Memory: it allows to select the memory device where the data will be recorded. It is possible to select between the internal memory (INT) or the SD memory card (CARD).

• Serial Device: it identifies the device connected to the serial interface.

The connection possibilities are:

ƒ RS232: connection to a PC with COM ports or to a printer with RS232 serial interface

(for example HD40.1).

ƒ USB: connection to a PC through USB port. The connection to the USB port of a PC requests the installation of the apposite driver included in the Noise Studio CD-ROM.

Measurements

Under the item MEASURES there are the general acquisition parameters.

• Application: it is possible to choose the type of measure between the vibrations transmitted to the hand-arm system (HA), to the whole body (WB) or by buildings

(BV).

• Input Gain: select the appropriate input gain among 0dB, 10dB or 20dB, according to the vibrations level to be measured (see the technical data).

• Integration Delay: It allows to start the measurement after a stabilization interval settable from a minimum of 2s to a maximum of 99s.

• Integration Mode: the instrument has two different integration modes: single (SING) and multiple (MULT). The single mode resets the integrated levels at the beginning of the measurement and integrates in the Tint time set in Menu>>Parameters >> Instrument >> Measurement >> Int. Integration. At the end, the instrument stops automatically the measure.

The multiple integration mode divides the measurement time in intervals equal to the Tint integration time set in Menu >> Parameters >> Instrument >> Measurement

>> Int. Integration. At the beginning of each interval the integrated parameters are reset automatically. For a description of the modes, see the “MEASUREMENT MODES” chapter.

• Profile Sampling: sampling interval in the visualization of the time profile, settable from a minimum of 1s to a maximum of 1 hour.

• Integration Interval: in single integration mode, this parameter acts as a timer that stops the display updating (HOLD), settable from a minimum of 1s to a maximum of 99 hours. If set to 0s, the timer is deactivated and the integration can only be stopped manually with the START/STOP key. In the multiple integration mode, this parameter determines the duration of each integration interval from a minimum of 10s to a maximum of 1 hour.

• Measure unit: the instrument shows in the VLM screens the acceleration levels with one of the following measure units: m/s 2 , cm/s 2 , ft/s 2 , in/s 2 , g and dB (referred to 10 -6 m/s 2 ). When a measure unit different from dB is selected, the acceleration values in the other screens are visualized in m/s 2 .

• Pond. CH-1: filter applied to the acceleration detected in channel 1 of the RIGHT input for the calculation of the vector acceleration.

• Pond. CH-2: filter applied to the acceleration detected in channel 2 of the RIGHT input for the calculation of the vector acceleration.

• Pond. CH-3: filter applied to the acceleration detected in channel 3 of the RIGHT input for the calculation of the vector acceleration.

• Pond. CH-4: filter applied to the acceleration detected in channel 4 of the LEFT input for the calculation of the vector acceleration.

• Coefficient 1: coefficient applied to the weighted acceleration related to channel 1 in the calculation of the vector acceleration.

- 60 -

• Coefficient 2: coefficient applied to the weighted acceleration related to channel 2 in the calculation of the vector acceleration.

• Coefficient 3: coefficient applied to the weighted acceleration related to channel 3 in the calculation of the vector acceleration.

• High-Pass: high-pass filter that cuts the frequencies lower than 0.6 Hz. It can be useful to decrease the settling time of the accelerometers signal and to improve the response to vibrations with frequent pulses.

• Ch1-4 0=OFF 1=ON: the function allows to disable one or more measurement channels that, for example, are not used. The status of each channel is described by a number: 0 (zero) indicates disabled channel, 1 enabled channel.

The four channels are indicated in the sequence CH1, CH2, CH3, CH4: to have them all active, the menu item must be Ch1-4=1111. To disable for example the channel CH1, the menu item must be Ch1-4=0111. It is not allowed to disable all the channels at the same time.

V IBRATION A NALYSER

Vibration Analyser Menu contains all the parameters related to the VLM_1, VLM_2 and

PROFILE screens.

These items can be modified directly in the correspondent screens as described in “DESCRIP-

TION OF DISPLAY MODES” chapter.

• Par. Axis. 1 ÷ Par. Axis. 3: measurement parameters visualized in the VLM_1 screen in relation with the measure of the acceleration values for a single axis.

• Par. Vect. 1 ÷ Par. Vect. 3: measurement parameters visualized in the VLM_1 screen in relation with the measure of the vector acceleration values.

• Profile: measurement parameter visualized in the PROFILE screen.

S PECTRUM A NALYZER

The Spectrum Analyzer menu contains the parameters related to the spectrum calculation and visualization modes. These items, excluded the parameter Order, can be modify directly in the Spectrum screen.

• Auxiliary Pond: the frequency weighting of the wide band channel associated with the spectrum and visualized with a vertical bar placed on the right of the display. The pondered level is calculated weighting, according to the selected filter, the octave or thirdoctave bands levels.

• Mode: the updating mode of the octave or third-octave bands spectrum. It can be Multi-Spectra (MULTISP), maximum (MAXIMUM), minimum (MINIMUM) or Integrated

(AVERAGE). The multi-spectral mode provides a spectrum per second while the AVER-

AGE, MAXIMUM and MINIMUM modes respectively visualize the average, maximum and minimum spectrum integrated in the measurement time.

• Order: it allows to choice the order of the visualized spectrum: 1/1 for the octave bands spectrum and 1/3 for the third-octave bands spectrum.

• Spectrum Integration: this function of frequency integration allows to switch from the visualization of the accelerations spectrum (by selecting OFF that is “no integration”) to the velocity spectrum (X1: single integration) or displacements (X2: double integration).

The same setting can be obtained directly in measure mode through the arrow keys of the keypad.

D ATA L OGGER

In the recording menu are contained the parameters related to the storage of the measured data. It is composed by the two submenus Profiles and Global that are described below.

- 61 -

Profiles

It contains the markers and the profile recordings settings.

• Mark1 … Mark9: represent the available markers. During the recording it is possible to insert the markers to signal interesting events for the current measurement (for the details see the chapter (“RECORDING MODES”)

To assign a name to a marker:

• Use the UP and DOWN arrows to select one of the nine markers and confirm with

ENTER.

• The first character of the marker is selected and it can be modified by pressing the

UP and DOWN arrows.

• Press the right arrow to move to the second character, use the UP and DOWN arrows to modify the character.

• Repeat the previous two steps for all the characters that form the marker name.

• at the end press MENU to exit from the name editing mode.

Note: the markers can also be set by using the Noise Studio software.

• Mode: they are the two recording modes available Profile and Full.

“Profile” allows to memorize the profile of a measurement parameter (PROFILE screen), with the sampling interval set in “Menu >> Parameters >> Instrument >> Measurement >>Profile step” from 1s to 1 hour.

The second recording mode “Full”, when the integration mode is single (Menu >> Parameters >> Instrument >> Measurement >> Integration Mode) allows the recording of the profiles of the parameters visualized in the VLM_1 and VLM_2 screens and the spectra every second. When the multiple integration mode is active, it is also recorded the statistical analysis together with the VLM_1 and VLM_2 parameters and the spectra.

The recording interval is programmable from 10s to 1 hour (Menu >> Parameters >>

Instrument >> Measure >> Integration Interval).

ADC Channels: it sets the direct recording of samples (row signals) supplied by the AD converters. Through the UP and DOWN arrows it is possible to choose to record all the four channels (1234), only one at choice (1---, -2--, …) or the first three of the RIGHT input (123-). When “ADC Channels” is set on “OFF”, the ADC samples are not stored.

Note 1: it is not possible to select an ADC channel if the corresponding measuring channel CH is disabled: enable the measuring channels selecting MENU >> Parameters >>

FIRMWARE UPDATE

The firmware, the program that handles all the analyzer functions, can be updated transferring the file from a PC to the HD2030 through the serial port.

In this way it is possible to update the instrument functionality.

The updating files are available at the authorized dealers.

To proceed with the update, it is necessary to have installed in the PC the Noise Studio software.

Refer to the on line manual of the software for the operation details.

- 63 -

REPORTING OF LOW BATTERIES AND REPLACEMENT OF THE

BATTERIES

The battery symbol placed in the upper right corner of the display constantly indicates the charge status of the batteries of the analyzer. As the batteries run down, the symbol is gradually "emptied"…

... when the battery voltage reaches the minimum value to operate correctly, the symbol blinks. In this condition change the batteries as soon as possible.

Continuing to use the instrument, the battery voltage drops further, and the analyzer is no longer capable of providing a proper measure; any data recording is automatically stopped, finally the acquisition is also stopped and the instrument enters the STOP mode.

Below a certain level the instrument turns itself off automatically. The stored data remain. Below a certain level of batteries charge it will not be possible to turn on the instrument.

The charge level of the batteries is available in the main screen of the menu, expressed as a percentage value. The item is accessed pressing the MENU key. When the level is 0%, it is necessary to replace the batteries.

The battery symbol is replaced by a mains plug when the external power supply is connected.

Note: the battery symbol blinks also when it is disabled the automatic auto-switch off (Auto

Power OFF = OFF).

To replace the batteries, switch off the instrument and unscrew anti-clockwise the two closing screws of the battery compartment cover. After the replacement of the batteries (4 batteries type AA, 1.5 V alkaline or NiMH rechargeable), close the cover screwing the two screws clockwise. Check the date and time after the replacement of the batteries.

If the batteries replacement takes less than two minutes, it should not be necessary to adjust the clock.

- 64 -

Instead of alkaline batteries, it is possible to use rechargeable batteries NiMH type.

To allow the analyzer to properly manage the charge level of the batteries, it must be selected in the menu the type of batteries used (MENU >> Parameters>> Instrument >>

System>> Battery = Alkaline or NiMH).

The external power supply does not charge the batteries: rechargeable batteries must be charged separately with an external charger.

W ARNING ON B ATTERIES U SE

• If the analyzer is not used for a long period of time, remove the batteries.

• If the batteries are discharged, replace them immediately.

• Avoid leakage from the batteries.

• Use watertight and good quality batteries, alkaline or NiMH.

• If the product does not turn on after the change of the batteries:

• Remove the batteries

• Wait at least 5 minutes to allow a complete discharge of the vibrations analyzer internal circuit

• Insert the missing battery: with charged batteries, the instrument should switches itself on automatically.

INSTRUMENT STORAGE

Storage conditions of the instrument:

• Temperature: -25 ... 70 ° C.

• Humidity: less than 90% R.H. not condensing.

• In the storage avoid places where:

ƒ The humidity is high.

ƒ The instrument is exposed to direct radiation of the sun.

ƒ The instrument is exposed to a source of high temperature.

ƒ There are strong vibrations.

ƒ There are steam, salt and/or corrosive gas.

The casing of the instrument is made of ABS plastic material and the protective band is made of rubber: do not use solvents to clean them.

DIRECT PRINTER CONNECTION

The HD2030 analyzer can print the visualized levels in a format compatible with that of a portable printer with 24 columns like the HD40.1 printer.

The printer has to be connected to the serial port of the instrument.

Printer and vibrations analyzer must be properly configured.

HD2030 configuration

1. Set the parameter MENU >> Parameters

>> Instrument >> Input/Output >> RS232

Baud Rate: 38.4k.

2. Set the parameter MENU >> Parameters

>> Instrument >> Input/Output >> Serial

Dev.: RS232.

Printer configuration

1. The communication speed of the printer (Baud Rate) must be equal to the one set in the analyzer (38400 baud).

This is the only parameter requested for the HD40.1 printer.

The other connection parameters for printers different from the HD40.1 are:

2. Data bits: 8.

3. Parity: none.

4. Stop bit: 1.

5. Flow control (Handshaking): Hardware.

6. Automatic paper advance (Autofeed): enable.

Connect the HD2030 to the printer using the HD2110CSNM cable.

To proceed with the data printing:

• Switch on the instrument.

• Enter the MENU >> Parameters >> Instrument >> Input/Output and set the item: o

Printout =

ƒ VLM for printing the numerical parameters visualized in the VLM screen,

ƒ SPC for printing the octave or third-octave bands levels,

ƒ VLM+SPC for printing both.

• Start the measurement: when the instrument enter the stop mode, the data are automatically printed.

• To disable the printing, set the menu item Printout = OFF.

CONNECTION TO A PC WITH USB INTERFACE

The HD2030 can be connected to the USB port of a PC using the CP22 cable.

The connection through the USB port requires the installation of a driver supplied with the Noise Studio Software.

Before connecting the instrument to the USB port of the PC, install the Noise

Studio software.

With Windows 7 operating systems you need to start your PC by disabling driver sig-

nature, as explained in the USB drivers installation guide contained in the installation

CDROM of Noise Studio software

Proceed as follows:

1. Set the instrument menu item “MENU >> Parameters >> Instrument >> Input/Output >> Serial Device” to “USB”. Confirm and exit from the menu”.

2. Do not connect the instrument to USB port until requested from the wizard

3. Insert Noise Studio installation CD-ROM and wait for AutoPlay window to appear. In

Windows Vista and Windows 7 operating systems it’s shown the window below; select

“autorun.exe execution” (see “note 1” in the next paragraph)

4. The starting screen of Noise Studio will be opened: if the operating system prevents software to start, please see “note 1” in the next paragraph.

5. From starting window of Noise Studio click on “USB drive installation” to start the driver installation procedure.

6. The program checks the Windows ® a temporary folder. operating system version and copies related drivers in

7. At the end a message appears asking to plug the vibration meter connection cable to PC

USB port: press OK and close Noise Studio software pressing EXIT key.

8. Connect the vibration meter to USB port and turn it ON: when Windows recognise the instrument, it appears a message “ a new device has been detected”.

9. Wait some seconds until the message “new hardware is installed and ready to work” appears.

10. Driver installation procedure is ended: whenever the instrument will be connected it will be automatically recognized.

installation”. In Windows Vista and Windows 7 it appears an installation error under “device manager”: in both cases, cancel operation, disconnect instrument and restart the complete procedure starting from the beginning of this guide.

Verification of proper driver installation

To verify the proper installation procedure, proceed as follows.

On Windows 2000 and XP operating systems:

Select “START >> Settings >> Control Panel”, double click on SYSTEM icon. Select

“Hardware >> Device Manager”

On Windows Vista and Windows 7 operating systems:

Select “START >> Control panel”, then click on “Device Manager” icon.

Connect instrument to USB port.

The following items should appear:

• “Port (COM and LPT) >> USB Serial Port (COM#)”. The value # is the number as- signed to virtual serial port

• “Controller USB (Universal serial bus) >> USB serial converter”

- 80 -

When USB cable is unplugged, the above items will disappear and they will appear again as soon as the instrument is plugged to USB port.

In the documentation supplied with the Noise Studio CD-ROM, it’s available a detailed version, including pictures, of the USB driver management guide. Procedure to remove USB driver is also reported.

HOW TO SOLVE THE PROBLEMS

The HD2030 analyzer is equipped with a diagnostic program (DIAGNOSTIC CHECK) that checks automatically the main instrument parameters. To run the program and check the analyzer functions, press the keys MENU >> Programs >> Diagnostic Checks (see “PROGRAMS

DESCRIPTION” chapter).

If the DIAGNOSTIC CHECK fails:

Repeat it with new batteries after waiting the stabilization time (at least 1 minute) and, if the problem persists, contact the technical service.

R ESTORE OF F ACTORY S ETUP

The factory configuration of the analyzer parameters (factory setup) can be recalled through a key combination. This operation does not cancel the content of the data

memory.

With the instrument switched off, turn on the HD2030 keeping the ENTER key pressed.

All the parameters present in the menu are simultaneously set to the factory default.

V ARIOUS P ROBLEMS

If the CALIBRATION program with the calibrator fails:

Make sure the analyzer is not subjected to noise and/or high vibrations.

Repeat after the waiting the stabilization time and, if the problem persists, contact the technical service.

After changing the batteries, the instrument does not switch on.

Remove one of the batteries and wait 5 minutes before inserting it again. The instrument should switch itself on automatically when the missing battery is inserted.

The levels detected by the analyzer seem not corrected.

ƒ Make sure there is no condensation. Do not turn on the instrument if there is the probability of condensation.

ƒ Wait for the measures stabilization time.

ƒ Check the accuracy of the measurement with the calibrator.

The analyzer switches itself off automatically after the startup screen.

ƒ The batteries are discharged.

The instrument does not communicate with PC:

ƒ If you are using a communication program like HyperTerminal, check that the communication speed of the PC and HD2030 are the same (Menu >> Parameters >>

Instrument >> Input/Output >> Baud rate).

ƒ Check that the connection cable is correctly inserted and it is connected to a RS232 serial port or USB of PC

ƒ Check that the item MENU>> Parameters >> Instrument >> Input/Output >> Serial

Dev. is set to the port type in use: RS232 or USB.

ƒ If using the USB interface, check if the driver is correctly installed.

ƒ If you are using Noise Studio software, try to disable the Auto Detect function (Menu

Option >> Port Settings) and set the connection directly to the COM where the instrument is connected.

It is not possible to activate the continuous recording. Pressing REC and RUN keys the analyzer starts the measurement without recording.

ƒ The instrument has no available memory for further data. Download the data and/or erase the memory.

COMMUNICATION PROTOCOL

The commands are made by ASCII strings with variable length ending with CR-LF.

The instrument always gives an answer when it receives a command. If the command is not accepted, the answer string is always NAK-CR-LF. It is possible to deactivate the answer, when it is not explicitly requested by the command, acting on VERBOSE parameter (see PAR paragraph).

The commands are divided in 5 groups, as indicated in the following table.

Group N. commands Description

STT 3 STATUS: Analyzer Status

CNF 10 CONFIG: Sensor Config.

Each group contains a certain number of commands. Each command is identified by a specified string. The generic syntax of a command is the following:

<group>:<key>:<value>:CR-LF e.g.: “PAR:INPUT_GAIN:10\r\n”

Set the parameter INPUT_GAIN to the value 10dB (see the paragraph SET).

Only capital characters are recognized. Each token can be shortened to the minimum number of characters that uniquely identifies it. The example can be shortened as follows:

“PAR:INP:10\r\n”

In the following the possible formats of the commands are reported.

A3 - PAR:INT_TIME:<{SS,MM,HH}>:<value>CRLF

A4 - PAR:TIME:<hh>:<month>CRLF

A5 - PAR:DATE:<year>:< month >:<day>CRLF

A6 - PAR:x_AXIS_PARAMETER:<Parameter abbrev. >:<Parameter attribute>CRLF
