Ozone level meters display the input and output level for the left and right channels.
Range:
By default, the range of the meters is from 0 dB to -96 dB. You can adjust the range by pressing down the Ctrl key under Windows or the Command key under OS X and clicking with the left mouse button to expand the range or right to decrease the range.
Once you've zoomed in, you can change the viewing range by clicking on the range and dragging it up or down.
Peaks:
By default, the meters will hold peaks. You can configure this in the I/O tab of the Options Dialog, which you can also access by right-clicking (under OS X you can also ctrl-click) on the level meters.
To reset a peak that is holding, click anywhere on the meter.
Clipping:
Above the meter is a single red LED that serves as a clipping indicator. If the level reaches 0 dB at any point, this LED will light up and remain lit until you double click anywhere on the meter.
Options:
You can set the I/O meter options by opening the Options Dialog and selecting the I/O Options tab. You can also right-click (under OS X you can also ctrl-click) the I/O meters to bring up these options directly.
