Failure to observe the following procedures may result in serious personal injury To reduce the risk of explosion, do not mix used batteries with unused batteries or mix batteries from different manufacturers.
Contains built-in lithium battery (for internal date and time back-up). Do not incinerate or dispose of in fire. Do not disassemble, alter, or re-construct. Warning! Failure to observe the following procedures could damage the instrument. Read the manual before operation. Do not store in temperatures exceeding 60 C (140 F). Do not immerse in liquids. Condensation may damage your instrument. To reduce the risk of ignition of a flammable or explosive atmosphere, batteries must be changed only in a location known to be non-hazardous. Substitution of components may impair the accuracy of the instrument. Repair should be performed by authorized service personnel only. Caution! General The battery in this instrument has limited shelf-life, even if never used. A non-condensing environment is required for proper measurements. Battery run-time may be reduced when operating at lower than 0 C (32 F) temperatures. Batteries and Storage To reduce the risk of AA Alkaline batteries for leaking, it is recommended to: Remove the batteries from the housing whenever the NoisePro is stored for approximately 2 to 3 weeks or longer. Replace the batteries when LOBAT message appears on the display of the NoisePro. For more information on replacing the batteries or recommended battery types, please refer to Chapter 10, Replacing batteries and Approved batteries. Intended Use: The NoisePro is intended to measure sound pressure levels in air and provide personal noise exposure measurements. Recordings are performed in studies, and studies are grouped together in a session. A typical session consists of the recording of multiple studies in a work day, where the studies are separated by paused periods that allow time for work breaks and the lunch period. If you are using a DLX model, you can group studies in separate sessions and store as many as 100 sessions at one time in the instrument s memory. For the other NoisePro models, all of the studies stored in memory are part of the same session.
Session results are derived values based on the results for all studies in the session. For example, the start and stop times of a session are determined by the first and last studies in the session. The dose for a session is the accumulation of the dose results for all studies in the session. The maximum sound level for the session is the highest value of all the maximum sound levels obtained during the studies in the session. All measurements obtained for a study have their counterparts in session results. Logging In addition to making overall measurements, the NoisePro DL and DLX models save results periodically in a process known as data logging. Logged results are for a particular logging interval and don t depend upon other logged values or overall values for the study. The DL logs measurements automatically and needs no setup. For the DLX models, you can control what gets logged and the logging interval, and you can vary logging conditions in different sessions. Ar ea monitoring With its standard, shoulder-mounted microphone and dosimetry interpretations ( Interpreted summaries on page 44), NoisePro is optimized to make dosimetry measurements. It can also perform area monitoring, whether accumulating dosimetry information or not. Using NoisePro for area monitoring is equivalent to putting it to work as a sound level meter. Sound level meters require a different type of microphone attachment. While a shoulder-mounted microphone is best when monitoring for personal noise exposure, a rigid mounting is better for area monitoring. For that reason, Quest makes a boom- D 13 INTRODUCTION Session time line 3 mounted microphone as an optional attachment. For information about installing the boom microphone, see Assembling on page 7. You can perform area monitoring without recording data because sound levels are being measured even when no study is being performed ( SLM measurements on page 44).
But you can also record the results if you wish using all the features of the NoisePro for dosimetry, including running studies automatically and communicating the results to external devices. Session time line Figure 1 1 illustrates a recording period in which two studies are conducted and logging performed. For a DLX, this illustration represents the first of possibly multiple sessions recorded into memory because it is preceded by a Reset. For the DL and DLX models, the short dashed lines across the waveform indicate that logging is occurring.

The session run time clock stops. No data recording, but sound level monitoring could still take place. Begins Study 2. The session run time clock resumes. Ends Study 2. The session run time clock stops again. Run Time The time period of a study is the study s run time. The time period of a session is the sum of the run times of the individual studies in the session. The session run time begins at the beginning of the first study and ends at the end of the last study in the session, with pause times omitted. Use the cover Remember to replace NoisePro s cover when you don t need to get at the controls. It helps even when you re running an Auto-Run study. The cover guards against damage and prevents the unintentional operation of the instrument. For an orientation to the case and controls features discussed in this chapter, see NoisePro case and controls, on the facing page. Assembling If your instrument is a NoisePro DLX-1, you received a microphone cable assembly and separate microphone.
For all other instruments, you received an integrated cablemounted microphone, but you may be using the optional boom-mounted microphone. For information about using the corrector, see SLM measurements on page 12. NOTE: This microphone s grid cap is removable. Do not remove it and do not touch the diaphragm underneath. Class 1 microphone Position the microphone cartridge over the cable connector and screw to tighten. In accordance with the Class 1 microphone s packaging instructions, keep the microphone s center terminal from contacting first. After attaching the microphone to the cable, follow the instructions under Cable microphone on page 8 to connect the cable to the instrument. Random Incidence Corrector The purpose of this device is to improve the high frequency response of the Class 1 microphone under random incidence sound source conditions. To apply it, push over the tip of the microphone until the microphone seats against a lip in the corrector (approximately 1 mm from the end). D 18 8 FIRST TIME USE All other NoisePro models Frequency response curves for the microphone without the corrector are given under Class 1 microphone on page 87. Response curves with the corrector attached are provided with the Class 1 microphone. All other NoisePro models Cable microphone Attach by connecting the cable to the instrument. To install 1. Rotate the cable connector to align it properly with the Microphone Connector. There is only one way that it fits. 2. Push it straight in. The connectors automatically latch together. To remove 1. Grab the ring in the middle of the cable connector. 2. Pull it straight out. The ring slides to unlatch the connectors. Boom microphone The boom microphone is an optional type 2 microphone assembly. To install 1. Line up the boom connector with the Microphone Connector. There is only one way that it fits. 2. Plug in the boom connector. 3. Screw to tighten by rotating the boom connector s knurled ring clockwise. To remove 1.
Unscrew to release the boom connector s knurled ring. 2. Pull the boom connector straight out of the Microphone Connector. See NoisePro case and controls on page 6 for the locations of these keys. That key is shown at right. Press to power NoisePro on. To power it off, press again and keep depressed during a countdown. The symbol is, in reality, for the same key but denotes the key s escape function (backing up to a previous display) that you use to move backward along a display path. NOTE: You will not be able to power NoisePro off while a study is running. Verifying batter y power With the instrument on, look in the lower right corner of the display for a symbol like the one shown at the right. The dark bar in this icon shortens to the right as battery power decreases. When battery power gets down to an estimated eight hours of run time, the battery icon is replaced by the word, LOBAT. When LOBAT appears, consider replacing the AA batteries to ensure enough power to complete your studies ( Replacing batteries on page 65). Esta bl ishing oper ating conditions NoisePro is shipped with default settings that enable you to get started right out of the box, but you may want to changes some of the settings. Displays and the clock You may want to customize display characteristics and verify, or change, clock settings before running studies. To work in Setup displays 1. In the Start display, press until SETUP is highlighted. 2. Press. The Setup display appears. D 20 10 FIRST TIME USE Selecting logging options (DLX models only) 3. Press to make your selection. Select TIME-DATE to set the clock. Select DISPLAY to control backlighting and pick descriptors. 4. For details on working in these and other setup displays, see Setup display on page When finished changing settings in any Setup display, press to escape to the previous display (more than once to keep backing up to previous displays).
Selecting logging options (DLX models only) In the DLX, you can choose logging parameters such as what gets logged and at what rate. See Logging on page 26 to learn about these procedures. Choosing dosimeter setups All NoisePro models operate with multiple dosimeters at once, and each dosimeter can be assigned a setup from among the nine setups available. For information about these setups, including how to view them, change them and assign them to the dosimeters, see Chapter 4, Configuring dosimeters. Calibr ating It s wise to calibrate both before and after each study. The instrument will display precalibration and post-calibration information for your field review plus store it with the data for later review and analysis (Chapter 2, Calibrations, ). D 21 FIRST TIME USE Preparing to measure 11 Pr eparing to measur e Reset session memory, attach the windscreen and mount the microphone and case in accordance with your purposes. Reset operation A Reset removes all data from session memory, so make sure you no longer need that stored data before resetting. You must be in the Start display to perform a Reset. If in any other display, complete whatever task you re doing in that display and press one or more times to get back to the Start display. In the Start display, press the RESET softkey and hold until told in the display that all studies have been cleared. Attach the windscreen Use the NoisePro windscreen for all measurements. A windscreen reduces errors due to wind turbulence and helps prevent microphone damage. After calibrating, push the windscreen over the tip of the microphone. It stretches for a snug fit. Microphone positioning You can use NoisePro for both dosimetry (personal monitoring) and sound level meter (SLM) measurements, but microphone positioning should be different for these two conditions. Dosimetry Clip the microphone to your shirt or collar (Figure 2 1) as high on the shoulder as possible and away from the neck.
If the noise seems to come from one direction, place it on the shoulder closest to the noise source. During monitoring, keep clothing from coming into contact with the windscreen to avoid erroneous noise artifacts. If you have the optional microphone clips, use them to keep the cable from disturbing the microphone position (( Optional accessories on page 100). NOTE: To use the DLX-1 model for dosimetry, attach the Random Incidence Corrector furnished with the Class 1 microphone. 22 12 FIRST TIME USE Microphone positioning Figure 2 1: Shoulder-mounted microphone Clip the instrument s belt clip over your belt. If using the optional vibrating belt clip (or need to go back to the standard belt clip) see Exchanging belt clips on page 67 to install the appropriate belt clip for your purposes. SLM measurements You should do your best to minimize sound reflections, diffractions and absorptions caused by nearby objects, including the operator (free field condition). Avoid placement near a wall or in a corner.when doing free field monitoring, do not use the Class 1 microphone s Random Incidence Corrector. If reflections, diffractions or absorptions from nearby objects are present, use the corrector for random incidence monitoring. Whenever possible, attach the instrument to a tripod. Quest offers two types of tripods as optional equipment ( Tripods on page 100). D 23 FIRST TIME USE Measuring noise levels 13 Orient the microphone depending upon whether you are doing free field or random incidence monitoring. During or after a study, you can open the Results display to examine a wide variety of level, average and dose measurements obtained with multiple dosimeter setups. Running studies Start and stop studies using the key shown at the right. When a study is running, a Run Icon ( )appears just to the left of the battery icon at the lower right corner of the display. When the session is paused, a Pause Icon ( ) replaces the Run Icon.
After a Reset that clears memory, a Session Closed Icon ( ) appears in that location. Viewing results Examine noise measurements and other information in the Results display ( Results display on page 41). To view results 1. In the Start display, press to highlight VIEW CURRENT STUDIES. 2. Press. The Results display appears (Figure 6 2). Press the LEVEL, AVG, DOSE and SUMRY softkeys to cycle through measurements and a measurement summary. Press to switch between the instrument s dosimeters and view measurement results for each dosimeter. 3. Press to return to Start display. You can segregate studies into separate sessions by closing the current session. A new session will open when you start the next study. To close a session 1. In the Start display, press until CLOSE SESSION is highlighted. 2. Press. The session closes immediately. A few wor ds a bout displays The NoisePro starts in the Start display, which is shown below. From there you can branch to other displays, and in some cases to even more displays in a cascading fashion. Navigation Line Session Closed Icon Battery Icon Menu Options Softkey Functions Softkeys Figure 2 2: Start display and softkeys Most displays contain Menu Options, a Navigation Line at the top and Softkey Functions along the bottom. Select a menu option with the keys. The Navigation Line tells you what displays preceded the current display along a display path. To get back from any display to the previous display in the cascade, the general rule is to press (In some cases you re taken back automatically.) The Softkey Functions identify the purpose of the softkeys that are located directly below the display. Softkey functions are generally different for different displays. D 25 CHAPTER Calibrations 3 Noise measurements are only as good as the calibration of the measuring instrument.
To assure yourself that your NoisePro dosimeter is functioning within normal tolerance limits, return it to the factory periodically for a factory recalibration ( Factory service on page 71). This chapter explains how you can verify measurement calibration as part of your normal operating procedures. Field calibr ator The Quest calibrator is a portable device emitting sound at a fixed frequency and sound level. For some calibrators, the signal frequency and sound level can be selected. For all calibrators, the indicated frequency and sound level is specified on the calibrator. NOTE: Calibrators can be affected by changes in altitude and barometric pressure, and sometimes corrections are necessary. See your calibrator s user manual. Calibrate the calibrator The conformance of a field calibrator to its specifications should be periodically checked as well. To have a Quest calibrator checked, return it to a factory-authorized service center ( Factory service on page 71). Perfor ming a field calibr ation Preliminary steps Stop the current study. You cannot calibrate while a study is running. If the windscreen is on the microphone, remove it. The instrument must be ON with the microphone connected to it. Check the instrument battery indicator. If LOBAT is showing, replace the instrument s batteries before proceeding ( Replacing batteries on page 65). D 26 16 CALIBRATIONS Assemble Check the calibrator battery indicator. If the LOBAT indicator is ON, see the calibrator s user manual to replace the calibrator batteries before proceeding. If the calibrator has a selectable frequency setting, set it to 1000 Hz.
