due to its auto-ranging feature and simple push-button operation, this sound meter is extremely easy to use. Just switch it on and it is measuring with the most common settings: "a" frequency weighting and "fast" time response. At the push of a button you can change it to display the "c" weighted sound level or change to "slow" time response. The large display with back light make this meter ideal for measuring noise levels where the natural light is poor.
