ST203 Wire Tracker is used to identify and trace wires or cables within a group without damaging the insulation. For telephone line, it can identify some state in the line, and more convenience to install, debug and maintain telephone line. There is a Sender and a Receiver included in the cable tracker.

nCable state testing:

1) Line DC detecting and anode, cathode determinant.

2) Open, short and cross testing.

3) Bell signal detecting.

nVolume regulates: according to regulate the sound magnitude.

nFunction of speed regulating: choice speed on testing.

nFunction of the earphone: in noisy environment, earphone can be used to prevent interference from the outside.

nVolume adjusting: while find a wire, volume knob can be rotated for moderate level of sound.

nSpotlight: can easily work as usual while putting on the light switch at night and in the dark

nDirectly hunt 5E, 6E, telephone wire, coaxial cable, USB cable and other cables

nCheck wiring error in 5E, 6E, telephone line, coaxial cable, USB cable and such as           open circuit, short circuit, jumper • wire, reverse connection or cross-talk interference

nLocate the wiring or connection error

nMeasure cable length and determine the distance of open circuit and short circuit

nDynamically calibrate cable length and make length measurement as accurate as 97%

nPortable unit with long battery life (wait-case 50 hours)

nAutomatically time-delay shut off and backlight display function

nMeasure length and pair with or without far-end recognizer

nLocate cable and there are 8 far-end passive test jacks (ID No.ID1-ID 8)

nFar-end recognizer with prompting voice

nSelf-checking function and automatically compensate any change in battery capacity or ambient temperature
