1. Summary
This Telephone Line Tester is one portable and intelligent line fault tester, which adopts
advanced technologies such as intelligent CPU, IC & SMT technology. It integrates various
kinds of functions such as telephone, line performance test and safe test to be the one.
The incoming call number display function is compatible with FSK/DTMF two types. Its
particular function of AC voltage detect and test can judge whether there is dangerous AC
high voltage in the line or not quickly and accurately in order to protect lineman from high
voltage.
The tester is designed following the human engineering theory with the appearance style like
barbell, it can be put on the shoulder, the lineman can do other work using hands at the same
time; besides, it can be hung in the tool belt of waist through the pothook, it is convenient to
realize the talk function cooperate with the high quality earphone when the lineman is
climbing or doing other things; inner chargeable NI-MH battery can works about one week
after full charging; the shell is made of the new type of material and it is solid.

6.1.5 Mute function
Loose all keys, connect clamps to the telephone line, press Hook and then press “MUTE”,
the other side can not hear our voice, and press “MUTE” again, it becomes normal.
6.1.6 P/T transfer function
Loose all keys, under hook-off status and no ringing signal, this tester can do P/T transfer
operation. Pressing “*” more than 3 seconds can realize pulse dialing and tone dialing
transformation, after successful transformation, the LCD will display “pulse” or “tone”.
6.1.7 High DC voltage indication
Connect this tester to the telephone line, if there is high DC voltage, the H-DCV light will be
bright all the time. Please do not off-hook in order to damage the tester.
Notice:
1. If the line has high AC/DC voltage, please do not use telephone function.
2. Only the line which has opened caller ID service can has caller telephone number function.
3. Line high voltage indicator can only apply to lines with low current and the range can not
exceed 250V.
6.2 Tester test
Press “Phone/Tester” and connect test line of tester to user line, which will be tested, you
can have the tests like followings:
6.2.1 AC V & DC V test
In the normal status, press “Phone/Tester” (“Phone/Tester” LED on) to have the voltage test.
It means that there is high AC voltage in the line if the LCD display like following and there is
fluting sound. Please take the clamp quickly.
~
The LCD will display the line voltage value automatically if there is DC voltage in the line. In
the following graph, it means that there is minus 64.6V DC voltage in the line; the line, which
is connected by the red clamp, is negative port and the black clamp is positive port.
－64.6V
Purpose: This function can be used to test whether the ringing up/off voltage of line is normal
or not; it can help lineman to distinguish the positive port and negative port of the line quickly
in order to ensure whether they connect the line correctly or not when install the relevant
equipment.
6.2.2 Insulation test
Press “Phone/Tester” in the normal status to judge there is no voltage in the line, and keep
5
TELEPHONE LINE TESTER
pressing “Test” about 3 seconds to test the insulation. The LCD will display the insulation
resistance figure automatically like the following graph. If the insulation resistance is less than
10MΩ and there is the fluting sound, it means that the insulation resistance figure of the line is
in small side; there is bad insulation fault.
16.4 MΩ
Please take off the user phone if you want to test the insulation resistance of the line.
It can be confirmed whether the fault has been canceled or not through the line insulation test
after check the user line.
6.2.3 Open test
In the normal status, connect the tester to the line which will be tested and press
“Pone/Tester”, after confirm there is no voltage in the line, keep pressing “Test” for about 3
seconds. It means that the line is break if the LCD only displays 9999MΩ.
6.2.4 Earth insulation
Like the above operation, connect the black clamp to earth line and the red clamp to the line
which will be tested. The LCD will display the earth insulation degree.
6.3 Call user & talk
Connect the test line of tester to passive user’s line, press “Phone/Tester” (“Phone/Tester”
LED on), press “Talk” after judge there is no voltage in the line and then press “Test”, you
can call user telephone of the line. After both sides is off hook, and loose “Test”, enable to
talk.
This function can be used to check the line maintenance.
6.4 Phone test
The phone quality of users can be tested by the tester.
Connect the tester line to the user phone through clamp or assistant line and ring the user
phone, it means that the user phone is normal if it rings normally; the phone quality is good if
the quality of the communication voice is good, otherwise, there are faults in the phone.
6.5 Check wire pairs
Firstly, side A and side B are in normal communication status from the agreed line. The man
in side A tell the man in side B which line links with the red clamp, and appoint this line as
6
TELEPHONE LINE TESTER
assistant line. The man in side B twist one of needing checking lines with the assistant line
and still keep in communication status with side A. Then, the man in side A use the assistant
line C which insert into the charge hole to touch the core line one by one, until both sides hear
flute sound , which means the same line in two ends. Then check other line in the same way.
6.6 Monitor
This function can monitor and check line without influence to the user normal communication.
① Press MON button
(
LED is on);
② Connect the two clamps to the line which is talking, the tester can clearly hear the voice on
the line.
6.7 High AC voltage detect and alarm
Press “Phone/Tester” and then press
has high AC voltage;
when the tester is near the line circuit which
LED is on and there is alarm sound. Please take care and
operate it carefully!
Purpose: the safety of the line can be tested before by using this function and to avoid the
danger effectively.
Notice: This function is the accessorial function, please operate it according to the
manual and the manufacturer does not respond for damages.
6.8 Under voltage self-checking
After press “Phone/Tester”, if it displays
and there is the sound “di di…", it means the
battery is low voltage. Please loose “Phone/Tester” and charge the tester. Please do the
charge before your using.
6.9 Charge
Insert the output plug of charger into charge hole, and then insert the charger into 220V
socket, the charger LED is on. The 8 to 10 hours charge duration is the best. Please do not
press “Phone/Tester” during the charge process; otherwise, there will be the fluting sound. If
you do not use the tester for a long time, please charge it full for storage, and charge the
tester every 30 days.

using earphone accessory can liberate the hands of the user.
7. Notes
Before using this tester, you should use high AC voltage detect and alarm function to
make sure there is no high AC voltage in the line, and use voltage test function to
make sure there is no high DC voltage in the line, after that, you can use other
functions, which not only protects user safety but also protects the tester from
damage.
◆ During the test, there will be the dangerous voltage in the line when you press the test
keys, please pay attention to the safe and do not touch the test clamp.
◆ If there is “V”, which is displayed in the LCD during the test, it means that there is high DC
V in the line, please take the clamp and pay attention to the safety.
◆ The distance where tester can detect the voltage is related to the high/low of the voltage
which is tested, the test environment and the weather; the voltage which is tested is higher,
the distance of electromagnetic eradiation is longer; the rain, snow and fog can absorb part of
electromagnetism, therefore, the test distance is small; if there is other bars such as the trees,
wall and so on, and they can absorb a part of electromagnetism and the distance is small.
◆ Please loose all the keys to avoid discharge of the battery when the instrument is not
used.
◆ Please check whether there is high AC V or DC V in the line or not before operate the
tester to avoid the damage to the instrument or person.
◆Take the clamp immediately if there is high DC V in the line.
