Cautions
Battery: the battery of our company
’
s optical time-domain reflectometer
adopts rechargeable lithium battery. When using the instrument after a long term
lying aside, charge the battery firstly. If the instrument is laid aside for more than 1
month, charge the battery in time to maintain the electricity in the battery. Do no
charge the battery over 8 hours. Do not take out the battery randomly. Do not
make the battery approach to fire and heat-flash. Do not open or damage the
battery. Do not touch the electrolyte of the battery, otherwise the eye, skin and
clothes will be injured and corroded.
Outside power supply: All OTDR series can use outside power supply. Requirements of
power supply: DC12V/3A, polarity: .
Avoid laser radiation: during measuring processing of optical fiber system, avoid looking at
the open optical fiber, optical fiber interface, optical fiber tie point and other optical source, etc;
otherwise, the eyes may come into contact with the transferred laser and be hurt.
z
When the optical time-domain reflectometer working, do not look at the laser outlet
directly;
z
After using, cover the dust cap onto the optical outlet of the optical time-domain
reflectometer;
z
Do not directly look at the disconnected terminal of the being tested optical fiber. If
possible, make the disconnected terminal of fiber optical point to a non-reflective
object.
