The VDV Scout Pro LT uses the capacitive properties of a cable to measure its length. One end of the cable should be connected to the
corresponding port on the top of the tester. The other end should be left disconnected or attached to the self-storing remote.
The Length Constant sections below discuss the best practices to follow when measuring length in order to achieve the most accurate
The length constant refers to the electrical characteristic of a cable used to characterize length. Every cable has an associated length
constant in units of picofarads per foot. Setting the length constant on the tester is important to obtaining an accurate measurement
from the VDV Scout™ Pro LT. The default length constants are as follows.
The length constant can sometimes be provided by the manufacturer of he cable (see EDITING LENGTH CONSTANT section). You may
consistency of the cable along its length.
The length constant can vary from cable to cable, even of the same type produced by the same manufacturer. It can also vary over
the length of one cable because the length constant is dependent on the physical properties of the cable, which may not be consistent
throughout the entire cable. The change in wire pair spacing through the cable can vary the length constant along the length of the cable.
When setting the length constant using a length of cable, the cable should be at least 50 feet long. This will yield a ±2% uncertainty

TESTING CONTINUITY - OVERVIEW
When testing for continuity of a cable, you are checking that all conductors within a cable are connected properly from one
TESTING CONTINUITY - TERMINATED RJ45/RJ12 CABLE
8-wire ethernet cables can have an additional set of errors. A miswire simply means that the pin on one side of the cable is not
connected to the identical pin on the other side of the cable (for example, pin 2 on one side is connected to pin 6 on the other side).
Testing continuity is not the same as testing bandwidth. More sophisticated testers exist for verifying the amount of data that can pass
1. Connect one end of the cable under test
to the RJ45 port (if you are testing an ethernet cable) or RJ12 port

to the corresponding port on the self-storing remote.

The VDV Scout™ Pro can assist in this in two ways.
The most convenient way to identify installed cables is by using ID remotes (5 of each LAN and coax are included in the
VDV501-809 kit, and 19 are included in the VDV526-055 LANMap Kit and the VDV512-056 CoaxMap Kit, sold separately). Using ID

the same standard is used at both ends of a run or patch cable. Mixing “A” and “B” creates a cross-over cable.
