Using Markers
Using Markers
You can use markers to view the position and relative power of an event.
Markers are available from the Events tab (when you modify or add an
event) or the Measure tab in the main window.
To move a marker:
1. Ensure that the
button is selected in the zoom button bar.
2. From the Measure tab, press the markers button until it displays the
desired marker.
In addition to the a, A, B, and b markers, you can also select the All
item.
3. Once the appropriate marker is selected, use the right and left arrow
buttons to move the marker along the trace.
Note: You can also select the marker directly on the trace display and drag it to
the desired position.
If a marker is moved closed to another one, both will move together. This
ensures a minimum distance is maintained between markers.
A marker may disappear from the trace after you zoom in (see Using Zoom
Controls on page 125). You can recall it by selecting a missing marker with
the Markers button or by using one of the arrows to bring the selected
marker back into the displayed area.
