Getting Reflectance

Reflectance is the ratio of reflected light to input light.

Note: If you are testing in Real time, the reflectance value you will get is not

necessarily accurate.

To get reflectance:

1. From the main window, select the Measure tab.

2. In the Results section, press the Refl. button. Markers a, A and

B appear on the graph.

3. Zoom in and position marker A on the linear area preceding the event

to be measured. For more information, see Using Zoom Controls on

page 123 and Using Markers on page 165.

4. Position submarker a at the beginning of the linear area preceding the

event to be measured.

5. Position marker B at the peak of the reflective event to be measured.

Note: Using this procedure, you can measure the reflectance of all the events in a

merged reflective fault event.

Note: For non-reflective events, ∗∗∗∗∗ will be displayed.
