Operating
Overview of operation
The list below is a brief overview of the steps for running a study.
Integrating measurements
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 LEQ values measured over the RT. When the
measurements are compared, the SPL values measure the maximum and minimum values
while the LEQ provides steadier readings over the length of the study.
Figure 1-4: Comparison of noise sampled over Run-Time (SPL & LEQ 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 LEQ/LAVG 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, LEQ/LAVG, LED Alert , MAX, MIN, Run-Time .)
5. Power off the instrument.

6Operating
Screen indicators
Screen indicators are a type of notification identifying measurement parameters &/or screen icons.
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.
LEQ/LAVG
Equivalent pressure sound level/Average sound pressure level –The true equivalent
sound level (or average SPL) measured over the integrating period. The term LEQ is used
when 3 dB exchange rate is applied; The LAVG 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 LEQ/LAVG, 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 LEQ/LAVG, 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.

7Settings
Settings
Typical sound level measurements are performed with Afrequency weighting, Slow
time response, and the factory default 3 dB exchange rate. If your application requires
other settings, please change accordingly.
Frequency weighting and time response
The frequency weighting and the time response can be changed on the instrument by
pressing the following when in stop mode.
1. To change Aor Cfrequency weighting, press key.
2. To change Fast or Slow time response, press key.
Exchange rate (ER)
The exchange rate can be set to either 3 dB (for LEQ values) or 5 dB (for LAVG
values). The factory default is set at 3 dB. To change, follow below:
1. While powered off, press and hold key and then press key.
2. The exchange rate screen (with LEQ /LAVG indicators) will appear. Press
key to change the setting.
3. Press key to accept the setting. (To cancel, press key.)
Charging
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

8Windscreen
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
Positioning and tripod mount
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.
