Noise Meter-Operating Procedures and Operating Procedures
1,Open the noise meter carrying case, take out the noise meter and put on the sensor.
2,Put the noise meter in A state, test the battery, and then calibrate the noise meter.
3,Adjust the measuring range of the instrument against the common environmental sound level size table.
4,Measurement: You can use the fast (measuring the instantaneous value of the environment with a large change in sound pressure level), slow (measuring the average value in the environment with a small change in sound pressure level), impulse (measuring the impulse sound source), filter (measuring the sound level of the specified frequency band) various functions for measurement.
5. Record the measurement data.
6,After the measurement, it is recommended to check the sensitivity of the noise meter with a sound calibrator again to ensure the accuracy and reliability of the measurement data.
7,Tidy up the equipment, disassemble the sensor and battery and put them back to the designated location.
Noise Meter - Sensitivity Calibration
To ensure the accuracy of the measurement, calibrate before and after use.
Fit the sound level calibrator on the microphone, switch on the calibration power, read the value, adjust the noise meter sensitivity potentiometer and complete the calibration.
