Length & VF
Knowing the
velocity factor, a physical
length of a cable can be easily calculated.
Press the
(Up) button and edit the
value of the velocity factor, then press
(OK) to start measurement.
To find the
velocity factor of an unknown
cable, press the
(Down) key and
enter the physical length, then press
(OK).
The velocity factor depends on a type of your transmission line.
For instance, RG-58 cable with polyethylene insulator has VF=0.66.
