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. More sophisticated 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.

2.
Detach self-storing remote from the tester body. (ID remotes cannot be used.)
Connect the other end of the cable to the corresponding port on the self-storing remote.
3.
Press the data button C or the phone button A on the keypad to begin the test on the ethernet cable or

2.
Attach a known good patch cable from the wall port at one end of the cable under test to the RJ45 port (for ethernet cable)
or RJ12 port (for phone cable) on the self-storing remote.
Attach another known good patch cable from the wall port at the other end of the same cable under test to the corresponding

Testing Continuity-Term Coax
1.
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.
Attach a second barrel connector (not included) to the other end of the cable under test.
3.
4.
Connect a numbered CoaxMap remote onto the second barrel connector.
Press the video button B on the keypad to begin the test on the coax cable.
