ST230F TELEPHONE LINE TESTER
9
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.
8. Accessories
8.1 Main test line
The soft test line has the terminal box and special clamps. The red line is the anode and the black line is
cathode when the voltage is tested; you can realize the connection with many kinds of plugs or sockets using the terminal
box of main test line and the assistant line; you can connect all kinds of telephone lines conveniently to have test using the
special clamps of main test line.
8.2 RJ11 linking line
It can be inserted into the socket in the wall or used to test the quality of telephone through the terminal box.
8.3 The American type plug line (optional)
It can be inserted into the special socket to have test through the Terminal box.
