OPTIONAL USE METHOD (PAIRED) :
Connect one test lead to a wire and connect the other test lead 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 the tone is cancelled.
2. 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 suspect
pair.
•
Speaker will receive tone which will be loudest on the target pair.
•
Alternative using LED by brightest LED indicate receive of tone from
the target pair.
•
Use LED in high background noise or many crosstalk wires, should
cancel brightness of background noise or crosstalk from LED.
Cancelling done by pressing button of
amplifier probe and touch
the tip to those wires which have
background noise or crosstalk .
Adjust down slowly the volume from high sound position until LED
brightness cut off or very fade. Then trace those wires which bright
LED indicate receive of tone from the target pair.
•
In noisy environment, Headphone can be used by connect to audio
jack on
amplifier probe for better hearing.
B) LINE TESTING BY TONE GENERATOR
IDENTIFYING TIP & RING
(
SWITCH TO “OFF”
)
1. Connect the RED test lead to a wire and the BLACK lead to a another
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.
IDENTIFYING LINE CONDITION
(
SWITCH TO “OFF”
)
1. Connect both test leads to the pair (a test lead on a wire).
2. Observe the LED:
1. A BRIGHT “GREEN” or “RED” LED indicates a CLEAR line.
2. No lamp indicates a BUSY line.
3. A BLINKING LED indicates a RINGING line.
VERIFYING LINES
(
SWITCH TO “OFF” THEN “CONT”
)
1. Dial the line to be verified.
2. While the line is ringing, connect both test leads to the pair (a test lead
on a wire)
