You arecautioned that changesor modifications notespressly
approved in thisdocument could voidyout authority to operate this
equipment.
To reduce the risk of fire or electric shock,do not expose this
apparatus to rainor moisture.
To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.
Use batteries
At the same time, can not use different style or different capacitance batteries. And only charge the rechargeable batteries.
Avoiding condensation problems
As much aspossible, avoid suddentemperature changes. Donot attempt touse the driveimmediately after movingit
from a coldto a warm location, to raising the room temperature suddenly, ascondensation may formwith in thedrive. If the
temperature changes suddenlywhile using thedrive,
Stop using itand take outbatteries for atleast an hour.
Storage
When long timeno use,must takeout the batteriesto avoid destroyingthe device.

Real-time and averagemeasurement
Real-time measurement canquickly judge basicfaults of opticalfiber. Press
button to start real-timemeasuring. During measuring,you can change
range, zoom inor zoom out. Press button again or button to
stop. The devicewill not analysesevent after real-timemeasurement in default.
Unless you turn on RT analyse in System settings, the device will analyse events
according to thelast refreshed waveform.
Average measurement canjudge the linecondition more accurate.It can geta
better SNR andfits high requirementcircuit. Press button to start. Usercan
set measurement timefrom 5 secondto 180 second.The device analysesevents and
generates event listautomatically. Press button during measuring,device
will stop measuring,analyses events andgenerates event listautomatically.

increase or decreasethe range. Andit also supports tochange the cursorposition
and zoom in/outwaveform in realtime, which means you can zoom in partial
waveform while measuring to judge the network fault.

Menu-Measure settings
Measure settings menu isused to set relativemeasurement data, which
the judgment of eventslist is based on.Wrong setting mightleads to wrong or
missing events.
Wavelength---wavelength of laser.
Scan mode---manual and automode. Under auto mode,it will match the
distance, range and pulsewidth.
Range---match with the lengthof measured optic fiber, usually over onelevel.
Pulse width---set the pulsewidth of output laser. Usually,small pulse width can
measure close event, largepulse width can measureremote distance, but
enlarge event's blind area.
Average time--- can setbetween 5 second and180 second as average
measurement time.
Splice loss---treat asan event whenthe loss is higher than setting value.
Reflection threshold---treat asan event whenthe reflection is higher than setting value.
End threshold---treat asthe end of optic fiber whenthe loss ishigher than setting value.
Refractive rate---represent theaverage refractive index ofentire optic fiber.
Scatter coefficient--- the intrinsicvalue of Rayleigh Scattering.
