Noise meter - operation steps and operation steps
Noise meter - operation steps
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 ambient 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.
Noise Meter - Sensitivity Calibration
In order to ensure the accuracy of measurement, calibration should be carried out before and after use.
Fit the sound level calibrator on the microphone, turn on the calibration power, read the value, adjust the sensitivity potentiometer of the noise meter, and complete the calibration.
