Using the NM102 Sound Level Meter

The NM102 Sound Meter has been designed to be quick and easy to use. The auto-range feature means that you do not have to select the measurement range before making measurements, which is a problem with most sound meters. With the NM102 you just switch on and it starts measuring the "A" weighted, Fast Sound Level, which is ideal for most applications.
