You arecautioned that changesor modifications notespressly
approved in thisdocument could voidyout authority tooperate this
equipment.
To reduce the riskof fire orelectric shock,do notexpose this
apparatus to rainor moisture.
To avoid electrical shock,do not openthe cabinet. Referservicing to qualified personnelonly.
Use batteries
At the same time, can not use different styleor different capacitancebatteries. And onlycharge the rechargeablebatteries.
Avoiding condensation problems
As much aspossible, avoid suddentemperature changes. Donot attempt touse the driveimmediately after movingit
from a coldto a warm location, to raisingthe room temperature suddenly, ascondensation may form with in the drive. If the
temperature changes suddenlywhile using the drive,
Stop using itand take out batteries for at least an hour.
Storage
When long timeno use,must take out the batteries to avoid destroying the device.

Real-time and averagemeasurement
Real-time measurement canquickly judge basicfaults of optical fiber. 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-time measurement in default.
Unless you turn on RT analyse in System settings,the device willanalyse events
according to thelast refreshed waveform.
Average measurement canjudge the line condition more accurate. It can get a
better SNR andfits high requirement circuit. Press button to start. Usercan
set measurement timefrom 5 secondto 180 second. The device analyses events and
generates event listautomatically. Press button during measuring,device
will stop measuring,analyses events and generates event list automatically.

The device supports userto change measurement range during real-time
measurement. Start Real-time measuringfunction and press Up or Down button to
increase or decreasethe range. Andit also supports to change the cursorposition
and zoom in/outwaveform in realtime, which means youcan zoom inpartial
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 when the loss ishigher than setting value.
Reflection threshold---treat asan event when the reflection ishigher than setting value.
End threshold---treat asthe end of optic fiber whenthe loss is higher than settingvalue.
Refractive rate---represent theaverage refractive index ofentire optic fiber.
Scatter coefficient--- the intrinsicvalue of Rayleigh Scattering.
