If the Markers appear off screen, use the Markers button on the right side bar to display the
Markers on screen.
If a marker is moved too close to another, both will move together to ensure minimal distance
between them.
The markers can be moved separately or in tandem (or 5 markers simultaneously in the LSA
attenuation measuring mode).
At the top of the screen next to the markers, the position of the marker with respect to the
beginning of the optical fiber is indicated in kilometers, miles or feet.
The parameters of the trace corresponding to the markers’ position and measurement mode
will be displayed at the bottom of the screen.
