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.
