AC and DC analog output can be connected to a frequency analyzer or XY shaft recorder do statistical analysis. Noise measurement [Application] factories, schools, offices, transportation routes, family, audio and other applications on various occasions [Steps] A. Turn the power switch. B. Press LEVER button, select the appropriate measurement position; not to appear 'UNDER' or 'OVER' symbol prevail. C. To measure the amount of noise that the feel of your choice 'dBA'; To measure the amount of mechanical noise analysis select 'dBC'. D. To select the amount of noise instant Please choose the FAST; if you want to get when the overall amount of noise, select SLOW. E. If you want to get the maximum amount of noise, minimum election 'MAX / MIN' function key, you can get the maximum and minimum values. F. handling noise or the noise table table mounted on a tripod, microphone distance to the sound source distance measuring about 1 to 1.5 meters.
