The result printed on a report summary can be a pass or fail, or warning. A failure
of any test required by the selected test standard produces a fail result on the
report summary. A warning appears on reports for twisted pair cable if a length,
impedance, propagation delay, or delay skew test produced a warning. The table
in Appendix C shows which test standards can produce a warning result for these
tests.
