The OTDR Port and End events always show N/A for

columns, the tester did not find the event at the
selected wavelength. Tap an arrow button (

 If the tester made measurements at two wavelengths, tap the
arrow buttons to see results for the other wavelength. Possibly,
some events show only at one wavelength.
 : The measurement is within the limit.
: The measurement exceeds the limit.
: The tester does not give a pass or fail result to the event. This
occurs for OTDR Port, Hidden, and End events. This occurs for all
events if you use the Document Only test limit because Document
Only does not have values for limits.
When you use a test limit that has a reflectance limit, Hidden
events show a FAIL status if their reflectance exceeds the limit.
To see details for an event, such as limits for measurements and
the SEGMENT ATTENUATION coefficient, tap the event in the
table.
