TESTING CONTINUITY - OVERVIEW
When testing for continuity of a cable, you are checking that all conductors within a cable are connected properly from one end
to the other.
Usually, faults occur when terminations on each side are not connected (an "open"), or when adjacent conductors are accidently
connected (a "short").

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).
Certain pairs of conductors are required to be twisted together from endpoint to endpoint. These errors are called split pairs, and
can be present in cables that don't have any miswires.
Testing continuity is not the same as testing bandwidth. Other testers exist for verifying the amount of data that can pass through
a cable.
1.
Connect one end of the cable under test to the RJ45 port (if you are testing an Ethernet cable) or RJ12 port (if you are
testing a phone cable) located at the top of the main tester body. If testing a wall port, connect a known good patch cable
from the wall plate to the appropriate port at the top of the main tester body.
2.
Connect the other end of the cable under test to the corresponding port on the testing remote (LOCATION ONLY ID remotes
cannot be used). If testing a wall port, connect a known good patch cable
†
from the wall port to the appropriate port on the
testing remote.
3.

Note: Only Klein Tools Universal RJ12 Jumper Cable (VDV726-125) or an approved equivalent should be used in the RJ45 jack of
the Test-n-Map™ ID Remotes. Using a non-universal RJ11/12 patch cable could result in damaged contact pins.

Attach barrel connector to the open coax port on the top of the main tester body.
2.
Connect one end of the cable to the barrel connector at the top of the main tester body.
3.
If testing a terminated coax cable, attach a second barrel connector to the other end of the cable under test.
This step is not necessary if testing an installed coax cable (cable attached to a wall plate).
4.
Connect a numbered CoaxMap™ Location ID Remote to the second barrel connector or attach one of the
Test-n-Map™ ID Remotes to the barrel connector.
5.
Press the video button

on the keypad to begin the test on the coax cable.
