OTDR-File Save
Press (Save) key to save �ile after test
complete, pop up the keyboard, enter the name of
the �ile, and press Enter to save the �ile. If the
automatic save (otdr) function is turned on in
"System Settings", it will be saved automatically
after the test complete without manual operation.
Auto-save function
Enter the system settings, open the auto-saving
function, the instrument will automatically save the
test �iles after the average or auto-test.
OTDR-File Operation
Press to enter the �ile list.
Press the key to open a folder or File.
F1：Open �ile
F2：Delete �ile
F3：Rename �ile

The function can be tested
automatically by one key, and the
information of the length of the link,
the type of event point and the position
of breakpoint can be displayed in a
graphical form. The result is clear and
easy to understand.
This function is used to test the power of
optical signal and insertion loss of
various devices and optoelectronic
components. It can identify and measure
the frequency of 270/330/1k/2kHz
frequency optical signal.

Visible red light (650 nm) is injected into the
optical �iber, and the position of the optical
�iber fault point can be judged conveniently
and accurately by observing the leakage
position on the measured �iber. It is suitable
for the detection of bare optical �ibers,
jumpers and other high loss sections caused
by near-end faults and micro-bending of
optical �ibers and cables which can leak red
light.
Avoid looking directly at the laser output port.
Laser can cause damage to human retina.

The wavelength of stabilized laser source is
the same as OTDR wavelength. It is used to
measure the parameters of telecommunica-
tion, CATV, LAN cable, insertion loss, isola-
tion loss and echo loss of optical passive
devices, and wavelength responsiveness of
detectors.
There are �ive modes of light source: CW,
270 Hz, 330 Hz, 1 kHz and 2 kHz.

RJ45 Line Tracker
Used for RJ45 cable length testing and wire
tracker.After the line-�inding function is activat-

distal end of the line-searching, and the sound of
continuous "drops and drops" is heard.
