OPERATION INSTRUCTION
TEST CONTINUITY
1. Use the Sender (switch to "CONT")
Connent the test leads to the object, use "CONT" postion.The green light of "CONT" indicates the continuity.(the resistance of line is less than 10kΩ)
2.Use the Sender (switch to "TONE")
a. Connect the test leads to a pair of cables, touch Receiver to the cables.If the two cables give high and same tones, it means that both of them have continuity. Otherwise, the cable which has lower tone doesn't have continuity.
b. Connect one test lead to one cable among a group of cables, connect another test lead and the other cables to earth ground.Touch the tip of Receiver to another end of cable mentioned above.Reception of tone means that the cable has continuity. (see figure)
IDENTIFY THE STATE OF WORKING TELEPHONE LINE
USE SENDER (SWITCH TO "OFF")
1. Identify TIP&RING:
Connect the red test lead to the side of one line and the black test lead to the side of another line.
a."CONT" indicator light is "green" when you connect the red test lead to the Ring(-)side.
b."CONT"indicator light is "red" when you connect the red test lead to the TIP(-)side.
2. Identify CLEAR, RINGING, BUSY state on the working telephone line:
Connect the red test lead to the RING side, black test lead to the TIP side, or connect RJ11 into the RJ11 socket on telephone.
a. "CONT" indicator is "green", which indicates a CLEAR Line. If "CONT" indicator is "red", which indicates the polarities were reversed.
b. "CONT" indicator does not glow or glow faintly, indicates a BUSY line.
c. "CONT" indicator brightly flicker "YELLOW", indicates a RINGING line. (Switch to "CONT" will terminate the call on the line)
