Help Using Digital SPL Meter (1 Viewer)

[Jeff Braun]

Hey guys, so I have a Radio Shack digital SPL meter, but I don't have the instruction manual, so I'm not sure how to use it. Specifically, I don't know how to set the unit so that it measures a certain frequency. Can anyone tell me how to do this? I suspect you set the dial, and make some other adjustment. Also, the dial only goes as low as 60, so I am completely clueless as to how you'd use the unit to measure sound at 20 Hz.

Thanks,
Jeff

Make sure you have it set to C weighting, slow response and 70db range.

What exactly does the range mean?

> The "Range" that will register on your meter set to 70 will be a 60 to 80db spread.

The manual can be found here:

And if you want to measure a certain frequency you need a source for test tones that will provide that frequency out of your speakers. A Stereophile test disk, for example.
