2). Press "Settings" key to enter setting interface
3). In "Function", select "P"(Path)
Press "↓" or "↑" key to make the gray cursor on "Function" menu bar. After
pressing "→" or "←" key between "L"(Location) "P"(path), select "P"(i.e. select the
path mode). After selecting the function, press "Start-Stop" key to exit the setting
screen and enter the sampling display interface.
The path mode is a combination with a path signal generator provided by the
manufacturer to work. Connect the line correctly between the signal generator and the
fault cable, and plug the power supply of path signal generator, then select the signal
frequency, and adjust the output power of the generator(i.e., the output current of
signal generator), and make sure that the output current value is greater than 50 mA
and less than 100 mA. Under normal circumstances, you can hear "beep" sound from
signal generator in the headphones of the location instrument.
Press "↓" or "↑" key to adjust the size of the sound heard, and press "→" or "←"
key to adjust the amount of amplification of electromagnetic receiver. Usually the
electromagnetic gain is adjusted to 20% - 60%, and voice gain adjustment for 50% -
80%. You can make an appropriate adjustment according to the specific circumstances
of the site.
After moving the probe matching with the location instrument, measure the
underground route of cable with maximum or minimum method according to "path
measurement principle"of the fifth behind.
While listening to the sound, LCD will display waveform of sound signal
emitted by the current path of signal generator after detector and prompt waveform
amplitude. according to the size of sound heard and magnitude of waveform observed,
it can be a reference instruction for underground route of cable.
