Edge Dosimeter battery care best practices.
The Edge dosimeter incorporates a Lithium Polymer battery as a power source that with proper care
should give years of operational service. (Three years is typical.)
Proper care includes these best practices:
After use, it is best to charge the Edge in an EdgeDock charger prior to storage for a
prolonged period. A prolonged period is considered to be 2 or more months. If the Edge is to
be stored for an even longer period, it is best to take the Edge out of storage and re-charge
the dosimeter every 2-3 months.
Charge the Edge in an EdgeDock before attempting to turn it on if the Edge has not been used
for a prolonged period or was stored in a lobat condition.
It is best not to store the Edge for any period of time in lobat condition.
If not using the dosimeter it is best to keep the dosimeter in a powered up EdgeDock.

1Dosimetry
1: Introduction
Dosimetry
Measuring noise in the workplace is an important
element of hearing conservation programs and
noise reduction programs. With a noise
dosimeter, you can assess and determine a
worker’s daily exposure to noise levels. This
information can be used to ensure compliance
with regulatory bodies or to ensure if hearing
conservation programs are needed.
Figure 1-1: Sample
measurement display
Overview
To get you started quickly with the Edge, the first chapter is dedicated to introducing basic noise
dosimetry terms and information. The subsequent chapters will guide you through setting up the
dosimeter, running studies, and assessing your results with easy to follow steps and illustrations.
CHAPTER
1

Overview
Noise dosimeter

Noise dosimeter
What is a noise dosimeter and how does it compute measurements?
Essentially, a noise dosimeter is composed of the following: a microphone with a preamplifier, a
weighted network, fast or slow response time, an internal clock, calculator, and memory to store logged
data.
The illustration below is a diagram of a basic noise dosimeter. The microphone will, when exposed to a
sound pressure, generate an electrical signal. The signal will be increased by a preamplifier, and then is
regulated to an applicable level by the range control (dB range). The signal then goes through a filter set
or weighting system. The next circuit is the response circuit, which controls the dampening of the
readout. The response choices are typically Slow or Fast. Finally, the results will display on the
dosimeter screen.
For computation and storage, the clock tracks the sampling time. Dosimeters record how long sound
levels exceeded a set upper limit. The calculator computes an LAVG, a dose, a TWA, and other data. The
memory stores all times, calculations, and measurements.
For post-processing, DMS is used to view and analyze your measurement results with the option to view
and/or print reports.

Overview
Range of sound
3
Range of sound
Sound pressure is measured in decibels, or tenths of a Bel. Sound pressure level is indicated as dB SPL.
Since the human ear can detect sounds with an extensive range of amplitude, a decibel scale is used to
simplify the measurement results. For example, the ratio between the threshold of hearing and threshold
of pain in the human ear if measured in true energy is 10,000,000 times! The same range using the dB
scale is 0 - 140 dB referenced to 20 µPa (Micropascals).
The quietest sound that humans can hear has an amplitude of approximately 0 dB. Prolonged exposure
to sound pressure levels exceeding 85 dB can cause permanent damage to the ear. Sound levels in
excess of 130 dB are more than the human ear can safely withstand and can result in serious pain and
permanent damage.
What do the standards say?
Many organizations have studied and analyzed the effects of high sound exposure on hearing. As a
result, standards were developed to regulate personal noise exposure. In the United States, the
Occupational Safety and Health Administration (OSHA), the Mine and Safety and Health Administration
(MSHA), and the American Conference of Governmental Industrial Hygienists (ACGIH) have all created
regulations and limitations on total permissible noise exposure. International standards are specified by
the health and safety regulations such as the European Union (EU) Directive 2003/10/EC. Additionally,
the International Electrotechnical Commission (IEC) IEC-61252 has specific guidelines and regulations to
monitor noise in the workplace.
To access these copyrighted standards, please refer to the following:
OSHA - http://www.osha.gov
MSHA- http://www.msha.gov

Overview
Applications of the Edge
4
Applications of the Edge
The Edge has a cable-free, mounted microphone that converts sound pressure into an electrical signal. This
signal is conditioned, monitored, and integrated over time in order to provide a host of automatically
calculated values that can be used in occupational and environmental noise assessments. Programmable
parameters permit the Edge to serve many applications. The Edge can be used in the following applications:
As a personal noise dosimeter - Used to measure a worker's daily exposure to
noise levels. This information can be used to ensure compliance with OSHA, MSHA,
ACGIH, IEC, or your own customized parameter settings to determine if your
workers are over-exposed to noise.
As a time-history monitor- Used to provide a worker's minute-by-minute noise
exposure levels. This data can help you identify major contributors to the average
daily noise exposure.
As a survey monitor
Throughout a plant/facility –used to oversee noise levels throughout an entire
facility. You can identify machines and equipment which produce harmful noise
levels.
Specific areas in a plant/facility- used to identify key areas as “noisy” and
implement noise control options. Employees may be exposed to unacceptable
noise levels.
As a peak dosimeter- Used to detect the highest level of instantaneous sound
pressure.
Time history: manufacturing
Peak Measurement:121.20 dB

eg5 Overview
The “eg5” model is an intrinsically safe instrument featuring simultaneous C and A weighted measurements.
The instrument will also calculate C-A. The “eg5” model features two virtual dosimeters with data logging.
Once the parameters are set and saved in the dosimeter, you can monitor two different dosimeters by a
single press of the Enter button. This will toggle you between the two dosimeters.
Figure 1-3: Parameter setup screen for eg5
NOTE on Edge 5-bay charger: If you are using a 5-bay charger, you may have various models docked
at once as indicated in Figure 1-3. The models selectable in the 5-bay charger section is dependent on if
you selected the eg3 & eg4 or eg5 models. DMS will display a green circle with a checkmark indicating a
docked, powered on Edge with the serial name. DMS will also display a checkbox in front of applicable
models that are selectable for setup parameters. (See Customizing set-up parameters” for more details.)
Virtual dosimeters
You can monitor and log noise studies by enabling two different parameter settings in one dosimeter, also
referred to as “virtual dosimeters”. For instance, you may want to set one dosimeter to log using the OSHA
HC (Occupational Safety and Health Administration - Hearing Conversation) parameters and also monitor
noise with the OSHA PEL (Occupational Safety and Health Administration –Permissible Exposure Level)
settings.
A few scenarios of virtual dosimeters include:
Industrial noise control, hearing conservation compliance, work site assessments, personal noise
verification, and military applications.

3MTMDetection Mangement Software (DMS)
3MTM Detection Management Software (DMS) is a software application designed by 3M that runs under
the Windows operating system. You can use DMS for a variety of functions related to the Edge
dosimeter and with many other 3M instruments. DMS has the ability to customize your set-up
parameters, display data, manipulate data, and create reports.
Loading
To load DMS software, follow the instructions on the back of the CD or download a trial version from
www.3m.com/dms.
It will automatically load the drivers for the EdgeDock1 and/or EdgeDock5. If loading from 3M Internet
site, please follow the directions online. www.3m.com/dms or access the 3M Detection Solutions home
page at www.3m.com/detection.
Docking station functionality
Depending on the kit you purchased, you may have an EdgeDock1 and/or an EdgeDock5. Both are
designed similarly with the same LED indicators. The main difference with the EdgeDock5 is that it has
five bays for docking, charging, and/or managing the dosimeters. If desired, the EdgeDock5 will charge
all docked instruments at one time.
The docking station serves a dual-purpose role. (See Table 2-2 for an explanation of LEDs and
components.)
1. It is used to charge the battery on the dosimeter(s).
2. It is used to communicate between the software (DMS) and the dosimeter (i.e., import, export
settings and measurement files).
