a
Check
：
Observe fiber setting in the V-groove. The fiber should
rest in the bottom of the V-groove, Reload fiber if it
does not rest properly.
a
Check
：
Fiber end-face should rest between the V-groove tip and
electrode centerline. It is unnecessary that the fiber
end-face be exactly at the midpoint.

Splicing Operation
The WY-725 uses image processing to identify abnormal conditions
that sometimes occur during the splicing process. A small portion
of these defects sometimes goes undetected and a poor quality
splice occurs. Visually inspect the fiber image on the monitor to
confirm acceptance or rejection during the various stage of the
splicing process.
(1)Start of splicing
Pressing
＜
＞
moves the left and right fibers forward. After
completion of cleaning arc discharge, the fibers stop at the
predetermined position.
a
Note
：
When the fiber are moving forward and they appear to hop up
and down, contamination may be present in the V-grooves or
the fiber surface, Clean the V-grooves and redo fiber
preparation.
(2)Cleave angle measurement and alignment operation
Visually examine the condition of the fiber end-face while the
splicer is in operation or at a pause.
a
Check
：
Even if no cleave angle error is displayed, press<
>and
redo fiber preparation if the following cases occur.
