The floating ruler assists with sample measurements using a sample number base other than the absolute sample numbers shown on the standard ruler at the top of the Waveform window.
You can display (or hide) a floating ruler and move it to a location in the Waveform window. The sample base (sample 0) of the floating ruler is the secondary cursor, or, if there is no secondary cursor, the selected marker.
The floating ruler button and the floating ruler itself are visible only when the secondary cursor (or selected marker) is present.
- Do either of the following to display or hide a floating ruler:
- Place the secondary cursor.
- Select a marker.
You only need to follow this procedure the first time. The floating ruler displays each time the secondary cursor is placed or a marker is selected.
Select the command again to hide the floating ruler.
