Measurement Considerations
1. Wind blowing across the microphone increases the noise
measurement. Use the supplied windscreen to cover the
microphone when applicable.
2. Calibrate the instrument before each use if possible. Especially if the
meter has not been used for a long period of time.
3. Do not store or operate the instrument in areas of high temperature or
humidity.
4. Keep meter and microphone dry.
5. Avoid severe vibration.
6. Remove the battery when the meter is to be stored for long periods of
time.
