Instructions for use of pulse sound level meter
The pulse sound level meter is not only a general sound level meter for measuring exponential time-weighted sound level, but also a pulse sound level meter. It is suitable for various industrial environmental noise measurement and environmental noise survey measurement. It is used for sound level measurement of environment, machinery, traffic, ships and other noises; it is suitable for industrial environmental protection, construction, sanitation, teaching and scientific research and other departments.
Instructions for use of the pulse sound level meter:
1. Selection of the use environment: Select a representative test location, and the sound level meter should be kept away from the ground and the wall to reduce the additional impact of the reflected sound from the ground and walls.
2. The weather conditions require that the sound level meter should keep the diaphragm of the microphone clean when there is no rain or snow. When the wind force is above level 3, a wind cover must be added (to avoid wind noise interference), and the measurement should be stopped for strong winds above level 5.
3. Open the carrying case of the sound level meter, take out the sound level meter, and put on the sensor.
4. Put the sound level meter in the measurement state, check the battery, and then calibrate the sound level meter.
5. Use the comparison table (commonly referred to as environmental sound level) to adjust the measurement range.
6. The following can be used fast (measure the instantaneous value of the environment where the sound pressure level changes greatly), slow (measure the average value in the environment where the sound pressure level does not change much), pulse (measure the pulse sound source), filter ( Measure the sound level of the specified frequency band) Various functions are used for measurement.
7. Record data as needed, and also connect to a printer or other computer terminals for automatic collection. Organize equipment and put it back in the designated place.
