Introduction to calibration and measurement methods of sound level meters
Sensitivity Calibration
In order to ensure the accuracy of the measurement, it should be calibrated 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.
Measurement methods
When measuring, the instrument should select the correct gear according to the situation, hold both sides of the noise meter flat with both hands, and the microphone points to the sound source to be measured. Extension cables and extension rods can also be used to reduce the impact of the noise meter’s appearance and human body on the measurement. The position of the microphone should be determined according to relevant regulations.
