Warning
The OTDR is a laser device. Users should always avoid direct eye contact
with the laser output. Users are strictly prohibited from using a microscope
or magnifier to observe the optical source output. The laser beam may cause
permanent damages to eyes when the energy of the laser beam is converged
on the retina.
When the OTDR is used to test an optical fiber, the working light cannot
exist on the optical fiber under test. Otherwise, the test result is
inaccurate. Even worse, the OTDR may be permanently damaged.
Precautions
Battery: The battery used by the OTDR is a rechargeable Li-ion battery.
If
the OTDR has not been used for a long time, charge the battery before using
the OTDR again. If the OTDR has not been used for more than two months, charge
the battery in time to ensure that the battery power is full. DO NOT charge
the battery for more than 8 hours. It is prohibited to remove the battery unless
otherwise authorized. Keep the battery away from the fire or strong heat. DO
NOT open or damage the battery. DO NOT touch the electrolyte of the battery;
otherwise, the electrolyte may damage your eyes, skin, or clothes.
External power supply: The OTDR supports the external power supply, which
should be DC15V/1.0A.
Laser radiation: When measuring an optical fiber system, prevent direct eye
contact with the open-circuit optical fiber, optical connector, splices, or
other optical sources. Otherwise, direct contact of the eyes with the
transmitting laser will damage your eyes.
DO NOT look at the laser output port with naked eyes when the OTDR is working.
After the OTDR stops working, cover the optical port with a dust-proof cap.
DO NOT look at the unconnected end of the fiber that is being tested with
naked eyes. If possible, point the unconnected end of the fiber to an object
that cannot reflect light.
