Noise meter: steps for use and steps for use
1. Open the carrying case of the noise meter, take out the noise meter, and put on the sensor.
2. Put the noise meter in state A, check the battery, and then calibrate the noise meter.
3. Adjust the measurement range of the instrument according to the common environmental sound level scale.
4. Measurement: Fast (to measure the instantaneous value of an environment with a large change in sound pressure level), slow (to measure the average value in an environment with a small change in sound pressure level), pulse (to measure a pulsed sound source), filter ( Measure the sound level of the specified frequency band) Various functions are used for measurement.
5. Record the measurement data.
6. After the measurement is completed, it is recommended to check the sensitivity of the noise meter with an acoustic calibrator to ensure the accuracy and reliability of the measurement data.
7. Organize the equipment, disassemble the sensor and battery, and put them back in the designated place.
