As the laseris harmful to the eyes, donot attempt todisassemble the cabinet.
Precautions for Use
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 within 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.
Due to technologyimprovement, product specifications are subject to change without notice.

Real-time and averagemeasurement
Real-time measurement canquickly judge basic faults of opticalfiber. Press
button to start real-timemeasuring. During measuring, you can change
range, zoom inor zoom out . Press button again tostop. The device
will not analysesevent after real-time measurement in default. Unless you turn on
RT analyse inSystem settings, thedevice will analyse events according to the last
refreshed waveform.
Average measurement canjudge the line condition more accurate. It can get a
better SNR andfits high requirementcircuit. 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.

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

Menu-Measure settings
Measure settings menu is used to set relative measurement data, which The judgment
of events list is based on. Wrong setting might leads to wrong or missing events.
Wavelength---wavelength of laser.
Scan mode---Manual and auto mode. Under auto mode, it will match the Distance,
range and pulse width .
Range---match with the length of measured optic fiber, usually over one level.
Pulse width---set the pulse width of output laser. Usually, small pulse width can measure
close event, large pulse width can measure remote distance,but enlarge event's blind area.
Average time---can set between 5 second and 180 second as average measurement time.
Splice loss---treat as an event when the loss is higher than setting value.
Reflection threshold---treat as an event when the reflection is higher than setting value.
End threshold---treat as the end of optic fiber when the loss is higher than setting value.
Reflective rate---represent the average refractive index of entire optic fiber.
Scatter coefficient--- the intrinsic value of Rayleigh Scattering.
Optical detector---set whether to check light input in the fiber before measurement or not.
Real time analyse---set whether to analyses events after real time measuring or not.
