There are several methods available to manually measure fiber characteristics. Prior to
performing manual measurements, it is important you become familiar with the Markers and
Zooming capabilities of the unit.

8.2.1 Markers Controls
Markers are provided to measure distances accurately. Depending on the measurement mode
and viewing window, one or more markers are available for use. The Markers can be moved
using the touchscreen or using the left/right buttons on the rubber keypad (not available on the
MTTplus or FX150 units).
The Markers display the following:
•
Distance from the start of the trace to Marker “A”
•
Distance from the start of the trace to Marker “B”
•
Distance between Marker “A” and Marker “B”
As you move the Markers, the distance information updates automatically.
The active Marker is depicted by two small arrows pointing inwards at the base of the Marker.
The Marker is divided into a thick (bottom) and thin (top) line. To move Marker A or Marker B
individually, select and drag the Marker on the thin portion of the marker. To move both
Markers together, select and drag any Marker on the thick portion of the line.
