Portable noise meter matters that should be paid attention to when using portable noise meter profile portable meter and mini noise, easy to carry, convenient carrying, work smart, not only accurate, precision and greatly improved the work efficiency. Factors affected the accuracy of noise meter working noise meter is mainly used to measure the noise, and the classification of noise measurement mainly has the following kinds: 1, from the measured object to points, can be divided into environmental noise, Sound field) The characteristics and the characteristics of the sound source measurement. 2, from the sound source or the time characteristic of the acoustic field to points, can be divided into steady state and transient noise measurement noise. Unsteady noise and periodic noise and random changes can be divided into noise and pulse noise and so on. 3, from the sound source or the frequency of the acoustic field characteristics, can be divided into the broadband noise, the noise of the narrowband noise and highlight the pure tone ingredients. 4, from the precision of measurement requirements, can be divided into precise surveying, engineering surveying and noise census, etc. Portable noise meter matters should be paid attention to when using 1, should first read the instructions before use, understand the use of the instrument method and the matters needing attention. Note 2, install batteries or external power supply polarity, don't do the reverse. Don't should remove the battery for a long time, so as to avoid leakage damage to the instrument. 3, do not remove the microphone, prevent rolls fall, need not when placed in order. 4, instrument should avoid are placed in high temperature, damp, waste water, dust and high in the air containing hydrochloric acid, alkali ingredients or chemicals. 5, do not remove the instrument without authorization. Such as the instrument is not normal, can send to repair the unit or the manufacturer maintenance. 6, noise meter note waterproof, prevent high-altitude fall off.
