1 SD-200 Overview
The SD-200 is intended to provide measurements of sound pressure levels in air.
With five easy-to-use keys, the keypad is used for powering on/off, viewing and/or
running measurements, navigating, and setting parameters. (See Table 1-2 for
more information.)
Note: for typical sound measurements when determining hearing protection,
the SD-200 may be set to A weighting with Slow response.

When powered on, a self test screen flashes with country code and revision level (e.g. U1.0)
and exchange rate (e.g.3 L
EQ
/5 L
AVG
). Then a measurement screen appears.
The measurement screen will display the current Sound Pressure Level (SPL) in dB or the
previously viewed screen prior to powering off.
Note: no screen indicator appears for SPL.
Figure 1-2: Powered on with SPL screen displayed
Once powered off, the SD-200 will save the instrument’s settings and measurements which
are displayed again when powered back on. The SD-200 will not power off while in run mode.
1. Press and hold key until OFF disappears. Releasing within two seconds will keep
the instrument powered on.
Note: while in run, the instrument will not power off until stop is pressed. If the
instrument powers off due to low battery, it will store the last viewed measurements.
(See “Resetting” for more information.)

3 Operating
The list below is a brief overview of the steps for running a study.
Integrating measurements compute the average value over a period of time. In many work
environments, noise levels may be highly variable making it difficult to assess the sound level.
With the averaging function, you will see steadier values over the Run-Time (RT).
The chart below depicts the SPL and L
EQ
values measured over the RT. When the
measurements are compared, the SPL values measure the maximum and minimum values
while the L
EQ
provides steadier readings over the length of the study.

EQ
values)
Quick Help List: typical sound session
1. Power on the SD-200 and ensure the windscreen is attached.
Note: if battery indicator appears, this signifies the instrument needs to be charged.
(See “Charging”)
2. Select the desired settings (A/C weighting, F/S response) and the desired measurement via
the keypad.
3. Position the SD-200 microphone so it is angled about 70 degrees from the noise source.
4. Measures: when first powered on, the SD-200 displays the current SPL or the last viewed
parameter prior to power off.
For integrated measurements, press key. (Noting the L
EQ
/L
AVG
values will provide
steadier values over a period of time.)
To view measurements, repeatedly press key and the SD-200 will toggle through
the various screens (SPL, L

Table 1-2: Screen indicators
Indicators
Explanation
SPL
Sound pressure level - The basic measure of noise loudness expressed in decibels. SPL uses
the ratio between a reference level of 20 microPascals (.00002 Pascals) and the level being
measured. It is displayed in decibels (dB).
MAX
Maximum sound level - The highest SPL measured during integrating period.
MIN
Minimum sound level - The lowest SPL measured during integrating period.
L
EQ/
L
AVG
Equivalent pressure sound level/Average sound pressure level The true equivalent sound
level (or average SPL) measured over the integrating period. The term L
EQ
is used when 3 dB
exchange rate is applied; The L
AVG
is used when 5 dB exchange rate is applied.
Battery
power
Battery indicator There are two battery indicator states.
When battery power icon appears, this indicates the instrument has low power and needs to
be charged.
Battery power icon flashing indicates the battery is charging.
Run
Run indicator - Signifies that you are measuring L
EQ
/L
AVG
, LED Alert , MAX, and MIN screens
over the Run-Time .
Detection
Detection icon Appears when viewing the LED Alert screen. (Note: LEDs will flash if set
points are met or exceeded. See “LED Alert” for more info.
Run-Time
Run-Time Indicates the time elapsed from the start of the run mode which is used to calculate
the L
EQ
/L
AVG
, LED Alert , MAX, and MIN values. Run-Time starts as minutes and seconds
and then changes to hours and minutes when 20 minutes is reached. It will display hours only
after 20 hours.
OL
Overload Indicates that the dB has exceeded the range of SD-200 (40 -130 dB).
UR
Under Range Indicates that the displayed measurement is below the linearity range (45 -130
dB).
F/S
Fast/Slow time response - The response time setting determines how quickly the unit responds
to fluctuating noise. Typically, noise is not constant. If you were to try to read the sound level
without a response time, the readings would fluctuate so much that determining the actual level
would be extremely difficult. While the terms slow and fast have very specific meanings (time
constraints), they work very much as you would expect. The fast response would result in a more
fluctuating sound level reading than would the slow response. (See Specifications, “Time
Response”)
A/C
A frequency weighting or C frequency weighting - These are frequency filters that approximate
the equal loudness response of human hearing at low, medium, and high SPL’s. A frequency
weighting is the most commonly used filter defined in the international standard IEC 61672:2003.
Common applications of A weighting include industrial noise applications and community noise
regulations (such as: manufacturing noise or machine shop monitoring.) The A frequency weighted
filter makes the sound level meter respond closer to the way the human ear responds to noise at
lower levels. It attenuates the low frequency noise below several hundred Hertz as well as the high
frequency above six thousand Hertz. C frequency weighting is intended to represent how the ear
responds to very high levels.
7 Settings
Typical sound level measurements are performed with A frequency weighting, Slow
time response, and the factory default 3 dB exchange rate. If your application
requires other settings, please change accordingly.
The frequency weighting and the time response can be changed on the instrument by
pressing the following when in stop mode.
1. To change A or C frequency weighting, press key.
2. To change Fast or Slow time response, press key.
The exchange rate can be set to either 3 dB (for L
EQ
values) or 5 dB (for L
AVG
values). The factory default is set at 3 dB. To change, please follow below:
1. While powered off, press and hold key and then press key.
2. The exchange rate screen (with L
EQ
/L
AVG
indicators) will appear. Press
key to change the setting.
3. Press key to accept the setting. (To cancel, press key.)
Using the computers USB port, the SD-200 is charged with a mini-USB
cable plugged into the bottom of the instrument. It will charge in 2.5 to 12
hours when the battery is fully discharged based on available power.
Note: when connecting the instrument to your pc, a new device hardware wizard
will appear. If you cancel the wizard, the instrument will charge without the
drivers. If you wish to install the drivers, they are located at:
http://3M.com/SoundDetector . Select “Learn More”, select “Support”, and
select the 3M
TM
Sound Detector SD-200 drivers.

it will no longer flash.
Charging indicator
When turned off, dashes will

8 Windscreen
The SD-200 features a removable windscreen. This is primarily used to reduce
noise effects from wind with minimal effects on the readings. It is recommended to
use the instrument with the windscreen on at all times in order to protect the
microphone.
When the instrument is shipped, the windscreen will be detached. To attach, slide
the windscreen completely over the microphone.
Figure 1-8: Windscreen attached
If hand-held, position the SD-200 microphone angling it at about 70 degrees
from the noise source. To place the instrument in a work zone/area, a tripod
may be used by connecting it to the tripod mount while positioning it at about
a 70 degree angle towards the noise source.

9 Calibrating
A field calibration may be performed before taking measurements to ensure
that your measurements are accurate for the current environment. An
optional calibrator and calibrator adapter are used for this procedure. (See
“Accessories” for more information).
1. While the instrument is off, press and hold key and then press
key. Then release the keys. “CAL” will appear on the screen.
2. Place the calibrator adapter and the calibrator over the microphone, and
then turn the calibrator on.
3. To adjust the level to match the calibrator, press either key to
increase or key to decrease.
4. To accept the level, press key or press key to cancel.
Figure 1-10: Calibrating the SD-200
In the event your SD-200 locks up for an unknown reason, the SD-200 is equipped with a
reset feature. To reset the instrument, press and hold key for at least 20 seconds and
then release the key. The instrument will power back on.
Note: after a reset, L
