the tester.
3. Press TEST key.
The tests are performed depend on whether a remote identifier
unit (ID) is connected to the end of the cable or not.

For twisted pair cables, when the tester checks for a cable
remote identifier unit (ID) at the other end of the cable and a
pass condition exists, the LCD will display the following
information.
m
m
If testing coaxial cable with a termination, the tester dispalys
the total resistance of the cable wires and the terminetion.
COAX ST = 49.0
Ω
Only coaxial cables must be unterminated for the tester to
display the cable’s length. If a coaxial cable is open looks just
like an unterminated cable, then a length measurement that is
less than the known cable length would indicate a possible
open in the cable.
The tester if a failure is detected, additional information can be
viewed with the ▼/ ▲keys. The failure messages refer to
individval wires rather than pairs of wires. The TEST mode
failure messages are described in following tables.

Split Pair
Display wire pairings that are
incorrect based on the cable

A short greater than 0

, will cause display a length greater
than the actual distance to the short. The tester uses 0

calculate distance to a short.

Good cable, no cable remote unit
detected or the tester may not
sense the remote unit.
