DANGERS, WARNINGS, CAUTIONS
DANGER
Failure to observe the following procedures may result in serious personal injury
+ Not for use in explosive or hazardous locations. This product is not intrinsically safe.
+ Contains built-in lithium polymer battery. Do not incinerate or dispose of in re.
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 outside of the temperature range of -4° F to 158° F (-20° C to 70° C).
+ Do not immerse in liquids.
+ Condensation may damage your instrument.
+ Substitution of components may impair the accuracy of the instrument.
Repair should be done 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 instruments
+ Do not charge the battery outside of the range of 32° F to 104° F (0°C to 40°C).
+ Battery run-time may be reduced when operating at temperatures lower than 32° F (0°C).
+ The SD-200 Sound Level Meter may not be sucient to carry out a full risk assessment of
workers exposed to hazardous noise levels to help comply with the European Physical
Agents (Noise) Directive 2003/10/EC. For further information contact a Safety
Professional or Industrial Hygienist.

Charging
It is recommended that the SD-200 is charged for approximately 12 hours before rst use.
Intended use
The SD-200 Sound Level Meter is intended to measure sound pressure levels in air and provide sound
and noise detection measurements. For suitability and proper use follow local regulations and refer to all
information supplied. For more information contact a safety professional.
Measuring sound pressure level
1 Place windscreen over microphone (if not attached).
2. Switch on the SD-200 and check that the battery indicator is not present.
+ If present, charge the instrument prior to measuring.
3. Select desired weighting and/or response time (A/C Key, F/S Key).
4. Position the SD-200 microphone at 0 degrees for the reference direction or at 70 degrees for
random incidence direction.
5. Measuring: When rst switched on, the current SPL will be displayed or the last viewed parameter.
+ For integrated measurements, press the Run/Stop Key. Unlike SPL, the LEQ/LAVG values will provide
steadier values over a period of time until values become more stable.
+ To cycle through the measurements, repeatedly press the mode key.
+ To stop measuring, press Run/Stop Key.
6. Switch o by pressing and holding the Power Key until it turns o (When not in Run mode).
NOTE: It is advisable to perform a eld calibration before taking measurements to ensure your measurements are accurate
in the current environment. An optional calibrator and calibrator adaptor are used for this procedure.
