Tracing twisted pairs
To trace specific twisted pairs and identify split pairs, connect one EasyFinder test lead
to one wire and connect the other test lead to the other wire. The wires must be from
the same twisted pair.
This can be done by connecting to a wall jack or by clipping to the open cable end.
While holding down the HIGH button, use the PROBE to find the wire pair at the other
end or at each distribution box. To determine the precise location, hold down the LOW
button and find the wire pair with the strongest signal.
If the pair is twisted over the entire length, this specific pair will be found. If a wire is
disconnected along the length or if the pair changes to a single wire (split), several
wires in the distribution box will carry the trace signal. This indicates a fault in the wir-
ing. You now have to go back and locate the fault.
When the cable ends are open, use a similar procedure; spread apart the wires and
move the PROBE flat over them while holding down the LOW button. When the test tip
of the PROBE is guided across the wires, the first wire of the correct wire pair displays
a high level, a minimum level is displayed in the middle, and the second wire again
displays a high level.
This distinctly identifies the wire pair. If you cannot find a minimum level, either it is the
wrong wire pair, or there is a cable fault that may have been caused by an interrup-
tion, crossed or split pair. The EasyFinder transmits the trace frequency at approxi-
mately 12 dBm in lines with a terminal resistance that can be as low as 50 ohm. You
can transmit on energized telephone or data lines. The maximum cable length for
detection is 15 km (no load).
CONT mode - continuity check/resistance check
Turn on the continuity test mode by setting the sliding switch on the right side to CONT.
This applies a voltage to the tested line making it possible to sense line continuity,
shorts or resistors up to 100 kOhm. The green LED CONT briefly flashes when the test
is activated or when the resistance at the test terminals is above 100 kOhm.
Depending on the level of the resistance, LED brightness will vary from light to dark.
This allows the resistance to be estimated. This is a good way to check if data cables
are patched to terminating equipment.
Low Batt - battery voltage level monitoring
When the unit is turned on and the internal battery falls below approximately 6 V, the
SOLID LED briefly flashes three times every 60 seconds to indicate low voltage.
When SOLID flashing is activated in TONE mode, the ALT LED assumes this function.
When 5 V is reached, the EasyFinder automatically turns off.
