MEASURING THE SOUND LEVEL

1. Turn the power/function/range switch to "dB" position.
2. Remove the meter and face the microphone to sound source in a horizontal position.
3. The C-weighting curve is nearly uniform over the frequency range from 30 to 10,000Hz, thus giving
an indication of overall sound level.
4. The fast response is suitable to measure shout bursts and peak values from sound source.
5. The sound level will be displayed.
6. Note: Strong wind (over 10m/sec.) striking the microphone can cause misreading for measurement
in windy locations, a windscreen should be used in front of microphone.
