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.
This display shows:
dBA - "A" weighted dB
Fast - time weighting
The "A" weighted, Fast Sound Level is the parameter that is used for most applications. When you need something different the meter has the following buttons:
|Switches between "A" weighting and "C" weighting.
For more information on these visit our Frequency Weightings page.
|Switches between "Fast" time weighting and "Slow" time
For more information please visit our Time Weightings page.
|Holds the sound level that is currently shown on the meter - freezes the display.|
|Shows the maximum or minimum sound level.|
