5.2. Measuring Sound Level
1.
Turn the Power/function/Range switch to „dB“ Position.
2. Face the microphone to sound source in a horizontal position.
3. Press Select Button: Selects A/C dB, Lo/Hi dB
4. The C-weighting curve is nearly uniform over the frequency
range from 30 to 10.000 Hz, thus giving an indication of overall
Sound Level.
5. The A-weighting is based on the human hearing and filters the
frequencies which normally can´t be heard by a person. It is best
suitable for measurements in buildings like in the workplace.
6. The fast response is suitable to measure shout bursts and peak
values from sound source.
7. The sound level will be displayed.
8. Note: Strong wind (over 10m/sec.) striking the microphone can
cause misreading for measurement in windy locations, a wind-
screen should be used in front of microphone.
