Figure 50 Manual Measurement results
Result of slope measurement
The result is displayed on the screen between the two slope indicators [ and ].
The measurement results are also available in the table:
1 Press Exit to return to the initial results page.
2 Select Trace using Trace/Summary soft key
3 Press validation key
– "Distance" shows the distance between the beginning of the trace and the end
of the slope;
– "Section" shows the distance between the previous event (which may also be
the beginning of the link) and the end of the slope. Thus this section value is not
equivalent to the distance between the two slope indicators [ and ].
– "Slope" shows the slope value in dB/km
If no result is displayed in the table, this means that the distance between the cursors A
and B is too small.
Deleting a slope measurement
To delete a particular slope measurement result:
1 Superimpose the cursors A and B on the slope concerned
to display results table under the trace.
