VEVOR ALK-T2 - Splicing Loss and Quality Evaluation; Fusion Splice Exception Explanation

2.6.2 Splicing loss estimation and quality
evaluation
After the splicing of the fibers has been completed, the
evaluation of the splicing loss is shown on the right side of
the display. The limit value for the splicing loss is set in the
menu [Fusion Splice Settings]. Note that the splice point
sometimes looks slightly thicker than the rest of the splice,
this is a normal splice and does not affect the splice loss.
