3. Touch the tip of the amplifier probe to the insulation of each suspect conductor.
4. Reception of the tone will be loudest on the subject wire.
5. The plug receptacle is provided to be connected to a headset or handset.
•
Identifying tip and ring (switch to "Off"):
1. Connect the RED test lead to one line and the BLACK lead to the other line.
2. The LED will glow GREEN when you connect the RED test lead to the RING SIDE of the line.
3. The LED will glow "RED" when you connect the RED test lead to the TIP SIDE of the line.
•
Identifying line condition (switch to "OFF"):
1. Connect the RED test lead to the RING SIDE of the line and the BLACK lead to the TIP.
2. Watch the LED:
a. A bright green LED indicates a clear line
b. No light indicates a busy line
c. A brightly flickering YELLOW light 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 the RED lead to the RING SIDE of the line and the BLACK
lead to the TIP.
3. In the "Off" position, the indicator light will flicker YELLOW when the test leads are connected to
the subject pair.
4. If you switch the test set to "CONT", it will terminate the call on the subject line.
•
Sending tone (switch to "TONE"):
(Caution: Do not connect to an active AC circuit exceeding 24V in this mode)
1. Connect the test leads to the pair, or attach one lead to ground and one lead to either side of the
line.
2. A dual alternating tone, or a single solid tone, can be selected from the switch inside the tone
generator.
3. Probe the suspected wires with the amplifier probe. Reception of the tone will be strongest on
the subject wire. In the case of ready access to bare conductors, a handset or headset may be
used to receive the tone.
•
Testing continuity (switch to "CONT"):
(Caution: Do not connect to an active AC or DC circuit in this mode)
1. Connect the test leads to the subject pair.
2. Use "CONT" position.
3. A bright GREEN light indicates continuity. The LED will not glow if the line resistance exceeds
10,000 Ω.
•
Testing continuity using tone (switch to "TONE"):
(Caution: Do not connect to an active AC or DC circuit in this mode)
1. Connect the test leads to the subject pair.
2. Use a handset or headset at the remote end and touch the wire end(s) with the clip lead(s).
3. Reception of the tone is an indication of continuity.
•
Modular testing:
1. All of the above tests are available through the modular plug for line 1 only – red and green
wires.
