Working with Application
Graphs
If you press the [Graph] softkey, a graph similar to Figure 108 appears. This
section explains how to use the graph.
There are four markers A, B, C, and D. You can use these markers to choose the
area of the graph that you wish to zoom into.
For the Logging and Stability applications, the time values of A and B are
displayed at the bottom of the screen in units of seconds. The symbol ∆ that is
listed directly beneath these values, displays the difference between A and B in
seconds.
For the PACT application, the wavelength values of A and B are displayed at the
bottom of the screen in units of nanometers (nm). The symbol ∆ that is listed
directly beneath these values, displays the difference between A and B in
nanometers (nm).
The power values of C and D are displayed at the bottom of the screen in the
chosen power units. The symbol ∆ that is listed directly beneath these values,
displays the difference between C and D in the chosen power units.
NOTE As a default, the C and D markers are out of range when you first open a graph.
See “How to Set Markers” on page 156, for more information on setting moving
markers.
