the coppers (4/8 wires for RJ11/RJ45 ) one end, and terminating
modular plug the other end.
OPTIONAL USE METHOD (PAIRED) :
Connect one clip to a wire and connect the other clip to the other
wire of pair(See figure 4). This method can further verify if tracing
pair is the target by momentarily shorting the pair at trace end and
found that the tone is stop.
2. PROBE TRACING
•
Press the round on/off spring-loaded button of the amplifier probe.
The volume control switch can be adjusted to suit the environment.
Do not adjust volume with sound too high for better identifying
target pair from crosstalk pairs
.
•
Touch the tip of the amplifier probe to the insulation of each
suspected pair.
•
Speaker will receive tone which will be loudest on the target pair.
•
Alternative using LED as visual tracing by observing its brightness.
Brightest LED indicate receive of tone from the target pair.
If using in high background noise or crosstalk ( other wires in group
also have tones). It may needs to set volume to the level which
cancel brightness of background noise or crosstalk from LED before
tracing. Setting done by pressing button on probe, touch the tip to
those wires which have
background noise or crosstalk, and adjust
volume down slowly from position high to low until LED brightness
cut off or very fade. Then start tracing
without adjusting volume,
which a bright LED indicate receive of tone from the target.
•
In noisy environment such as server room,etc., earphone can be
connected to audio jack for better hearing.
B) LINE TESTING BY TONE GENERATOR
IDENTIFYING PHONE TIP & RING
(
SWITCH TO “OFF”
)
1. Connect the RED clip to a wire and the BLACK clip to the other wire of
pair.
2. The LED will glow “GREEN” when you connect the RED test lead to
the RING SIDE.
3. The LED will glow “RED” when you connect the RED test lead to the
TIP SIDE.
VERIFYING PHONE LINE CONDITION
(
SWITCH TO “OFF”
)
1. Connect the RED clip to a wire and the BLACK clip to the other wire of
pair.
2. Observe the LED:
•
A BRIGHT “GREEN” or “RED” LED indicates a CLEAR line.
•
No lamp indicates a BUSY line.
•
A BLINKING LED indicates a RINGING line.
