ST230F TELEPHONE LINE TESTER
1. Summary
ST230F Telephone Line Tester is one portable and intelligent line fault tester, which adopts advanced technologies such
as intelligent CPU, IC & surface mounted technology (SMT) technology. It integrates various kinds of functions such as
telephone, line performance test and safety test to be the one.
The caller telephone number display function is compatible with FSK/DTMF two types. Its particular function of
automatically detecting high AC voltage test can test whether there is dangerous high AC 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 cooperating with the high quality earphone when the
lineman is climbing or doing other things; the max continuous working duration when the inside rechargeable Ni-MH
battery is fully charged is about 7 hours without replacing battery; the shell is made of new material and it is very reliable.

It means that there is high voltage in the line if the LCD display like following and there is fluting sound. Please take the
clamps quickly.
6
ST230F TELEPHONE LINE TESTER
~
The LCD will display the line voltage figure 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; then the line which is connected by the red clamp is positive port and the
black clamp is negative 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 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 20MΩ and there is a fluting sound, it means that the insulation resistance figure of the
line is small; 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 checking the user line.
6.2.3 Open line 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 MΩ.
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
Disconnect the local side, connect the test line to passive user’s line, press “Phone/Tester” (its right LED on), press
“Talk” after judging there is no voltage in the line and then press “Test”, and you can call user telephone of the line. (Call
LED on indicates the signal has been sent out); that Talk LED is on indicates user off hook, loose “Test” enable to talk.
This function can be used to check the line condition of repair.
6.4 Phone test
The phone quality can be tested by the ST230F.
Connect the tester line to the user phone through clamps 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
7
ST230F TELEPHONE LINE TESTER
On the one end(END A) of the cables, use the ST230F black alligator clamping one cable and red alligator clamping
another cable, On the other end (END B), we name the cable with red alligator as the assistant cable. Use the telephone
or ST230F clamping the same two cables to confirm normal talk. Then at the other end (END B), choosing any waiting
checked cable connects with assistant cable, after that, on the end (END A),
you should insert single alligator cable into
the charge hole, using this single alligator to connect any of waiting checked cables, when you hear the long “Du…” sound,
you find the checked cable.
6.6 Monitor
High resistance monitoring function helps operators choose/check line without influence to the user telephone and digital
service. This can less user complaints and avoids interruption of user data service.
Has high resistance monitor function,
Usage:
①
②
③
Press button
, the MONITOR indicator light is on. The tester enters into Monitor & Identifying state.
Connect line clamps to telephone line that is being used, the tester can clearly hear voice call in the line, and the
DATA-LED light will be bright accompanying the talk.
Connect clamps to ISDN network, DATA-LED light will be bright when user uses this service, and there will be rustle
sound in the receiver, if there is no user using this service, you will hear code stream sound like da,da…and
④
occasionally rustle sound.
Connect clamps to ADSL line, DATA-LED light will be bright when user uses this service, and there is no sound in the
line, if there is no user using this service, DATA-LED light is not bright.
6.7 High AC voltage alarm
Press “Phone/Tester” and then press
when the ST230F is near the line circuit which has high AC voltage;
LED on and there is alarm sound. Please take care and operate it carefully!
Purpose: the safety of the line can be tested before 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 caused by using this function.
6.8 Low voltage self-checking
After pressing “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.
6.9 Charge
Insert the output plug of charger into charge hole, and then insert the charger into 220V socket. The charge indicator light
8
ST230F TELEPHONE LINE TESTER
on the charger will be bright, which means the tester is in normal charging status.
The 7 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.
6.10 Accompanied earphone (optional)
Earphone jack is on the upside. Hang the tester in tool belt of waist or cable by Belt Clamp, using earphone accessory
can liberate the hands of the user to do other work at the same time.
7. Notes
Before using this tester, you should use induced voltage 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 status, there will be dangerous voltage in the line when you press the Test key, please
pay attention to the safety 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 clamps and pay attention to the safety.
The distance of induced voltage test is related to the high/low of the voltage which is tested, the test
environment and the weather; the higher the voltage which is tested is, the longer the distance of
electromagnetic eradiation is, and the longer the test distance is; the rain, snow and fog can absorb
part of electromagnetism, therefore, the test distance is small; if there is other barriers such as trees,
house, wall and so on, and they can absorb 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 (dialing
does not consume battery, only the test status, monitor or induced voltage can consume battery).
Please check whether there is high AC V or DC V in the line or not before operating the tester to avoid
the damage to the instrument or person.
Take the clamp immediately and do not do other operation if there is high DC V in the line.
