INSTRUCTIONS:
•
IDENTIFYING TIP & RING (SWITCH TO “OFF”):
1. Connect the RED test lead to the side of the one line and the BLACK lead to the
side of the another 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 (SWTICH TO “OFF):
1. Connect the RED test lead to the RING SIDE of the line and the BLACK to
the TIP.
2. Watch the LED:
1) A BRIGHT “GREEN” LED indicates a CLEAR line.
2) NO lamp indicates a BUSY line.
3) A BRIGHTLY FLICKERING “YELLOW” lamp 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 to the TIP.
3. In the “off” position, the indicator lamp 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 (SWTICH 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 the ground and one
lead to either side of the line.
2. A dual alternating tone, or single solid tone can be selected from the switch
inside the tone generator.
3. Probe the suspected wires with the amplifier probe. Reception of tone will be
strongest on the subject wire. In cases of ready access to bare conductor,
a handset may be used to receive the tone.
• TESTING CONTINUITY (SWITCHING TO “CONT”):
(CAUTION: DO NOT CONNECT TO AN ACTIVE AC CIRCUIT EXCEEDING 24V
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 10000 Ω
