VELOCITY SRCH.
This feature permits adjusting a cable’s Velocity Factor (VF) manually to get the
end of the cable or a known event on the cable’s trace to match a known length
measurement or measurement on a cable plat. Follow the on-screen instructions.
After the “Preparing” screen use the
◄►
keys to move the active cursor to a
known “target length” on the cable. When the cursor is in position, use the
▲▼
keys to adjust the VF higher or lower until the cable’s end or known event is
at the cursor. The resulting VF will be the cable’s actual VF.
Press
to accept the modified VF and return to the Measurement
Screen.
NOTE: The term “Target Distance” refers to a distance obtained by actual length
measurement in feet or meters, cable plat, or best estimated distance.
SAMPLE A CABLE
This feature permits measuring a cable’s velocity factor. It requires knowing the
cable’s length in feet and inches or meters to make that entry valid and obtain an
accurate velocity factor. A cable’s point-to-point measurement on a cable plat
will suffice as long as there are no undocumented maintenance loops in the
cable. Use
►
to select this feature and follow the on-screen instructions to
connect the cable, leave the opposite end open and mark the end with the
cursor. Pressing
will calculate and display the velocity factor to accept
or decline for use.
