Note
• When you set the markers, set them so that the
1
marker is on the measurement start point (distance
reference) side.
• The measured loss value differs depending on the specified approximation method.
• Distance Reference
Normally, the location where the instrument and the optical fiber cable are connected is the
measurement reference point. This reference point is the distance reference. It is used to
calculate the distance to the cursor and markers. If you are using a launch fiber to perform
measurements, move the distance reference the length of the launch fiber before performing
measurements.
Distance reference
• Cursor Link (Moving all markers together)
You can move all markers while maintaining the distance between them.
