Explanation
Editing Distances
• When you change the distance of an event, the section group index (section IOR) is recalculated.
• When you change the distance of an event but the event cannot be set at the specified position, the
distance is adjusted to a position where the event can be set.
• Changing the distance of an event affects the values of other events.
• You cannot change the distance of the distance reference (point R).
Editing Return Losses
When you change the return loss of an event, the backscatter level is recalculated. The return losses
of other events are measured on the basis of the recalculated backscatter level.
Editing Section Group Indices (Section IORs)
• When you change the section group index of an event, the distance is recalculated.
• You cannot change the section group index of the distance reference (point R).
