NVP

Nominal velocity of propagation. The tester uses the NVP
and the propagation delay to calculate the length of the
cable.
The default value is defined by the selected cable type
and is the typical NVP for that cable type. To enter a
different value, tap the
NVP
panel, then tap or
on the
NVP
screen to increase or decrease the value.
To find the actual value for a cable, connect a known
length of the cable to the tester, tap
MEASURE
on the
NVP
screen, then change the NVP until the measured
length matches the known length. Use a cable at least
30 m (100 ft) long.
When you increase the NVP value, the calculated length
increases.
