Setting the NVP percentage
Once in Calibrate Mode, the default NVP (Nominal
Velocity of Propagation) will be displayed followed by
the overall cable length. The cable length is measured
with the currently stored NVP.
NVP is the measure of how fast a signal travels down a
cable compared to the speed of light. The result will be
represented as a percentage of the speed of light. For
an accurate length test, the NVP must be set correctly.
