Change the NVP
The tester uses an NVP value (nominal velocity of propagation)
and the signal delay through a cable to calculate the length of
copper cabling.
The default value specified by the selected cable type is the
typical NVP for that cable type. The default value is usually
accurate enough for cable certification tests. To increase the
accuracy of length measurements you can adjust the NVP to a
specified or actual value.
Note
NVP values can be different among cable types,
lots, and manufacturers. Usually, these differences
are not large enough to change the PASS/FAIL
result of the length test.
