displayed, select soft key “ More ” until you come to the soft key
menu that includes:

Select INSERT EVENT from soft key menu, choose
placement type, then choose reflective or non-reflective…
• Non-Reflective:
use the dial to place the A cursor just before
the event. Once you push the dial button, the A cursor will
be set and now you control the B cursor, place that at the
end of the section you want to measure the event with. The
unit should display the location of cursor A (start of event) as
well as the measured loss between the two cursors. Select
“
Accept
” and the event will populate in the event table.
• Reflective:
Use the dial to position the A and B cursors the
same way you would to measure a non-reflective event.
However after this is completed, you must select the soft
key option “Measurement” until reflectance is displayed,
another B cursor will appear, use the dial to move it until
you reach the highest point of the reflective “spike”(use the
arrow keys to zoom in and out if needed). You will notice this
value change in the top left corner as you move the B cursor
around. When you get it to the proper place, select “ Accept ”.
Edit:
While having the event table displayed, use the dial to scroll
to the particular event you would like to edit. Then select “EDIT
EVENT” from the soft key menu. (Use the arrow keys to zoom in
or out if needed). Use the A & B cursors to re-measure an event
