Cable Testing General Guidelines
The CableMaster tests video, data, and voice cables to detect potential
faults, measures cable length, shows a cable’s wire pairing, and examines
the physical properties of a cable.
Important Points to Note
▪
The RJ jacks for data and phone cables share internal connections
within the tester. Only one RJ cable can be connected at a time for
accurate cable test results.
▪
An RJ cable and a coax cable may be connected at the same time. In ID
mode, all connectors on the Tester may be connected at the same time.
▪
To easily toggle between cable test modes, press the desired cable
type button.
Important Points to Note
The CableMaster is designed for use on unenergized cabling
systems. Connecting the CableMaster to live AC power may
damage the unit and pose a safety hazard for the user.
Poorly terminated RJ plugs, the head of a cable, have the
potential to damage the jacks on the CableMaster. Visually
inspect an RJ plug before inserting it into the tester to ensure
you are inserting the plug into the appropriate jack of the
remote-end or tester-end of the unit (ex. data cable plug fits
into data jack on the unit).
The cable’s contacts should always be recessed into the plastic
housing of the receiving jack. Plugging a 6-position phone plug
into the 8-position data jack on the tester has the potential to
damage the outer-most contacts of the jack. Insert the cable
into the appropriate connector on the remote end or tester end
of the unit.
