-
【FAST AND SLOW MEASUREMENT】 The noise meter decibel has the function of converting the fast and slow response rates. The fast response rate uses a time constant of 0.125s/time for general environmental measurement. The slow response rate uses a 1s/time constant, which is used for environmental measurements with relatively large changes in noise levels. Also, have MAX/MIN, data hold, and Auto/Manual range functions. Note: Can not keep and generate a report directly from the device.
-
【A WEIGHTING NETWORK SELECTION】 A weighting model: Simulate the characteristics of human hearing, which is suitable for the detection of ambient noise. This uses to measure the sound level of sound equipment in Work and Life: such as factories, workshops, schools, residential, office areas, traffic roads, audio, and other occasions. Also applies to noise engineering, product quality control, health control, and so on.
-
