4.2.11Refractive index can be modified between 1.0000-2.0000 by the operation of up and down
arrow. Then press IOR key to save refractive index and exit modification.
4.2.12 When checking high loss fault point or break point of short-distance optical fiber or pigtail,
visible fault location system is available. You need to exit automatic loop test pattern before using
the system. Please connect fiber with visible fault location port and press “GLINT” key, then you
will see red light in pigtail or break point of measured fiber. And press once more to exit visible
fault location system.
Notes: Please don’t look steadily at measured fiber or the end or break of pigtail to avoid damage
to eyes.

maintenance and preservation
The fiber port needs to keep clean, and the output port needs to be cleaned with absolute ethyl
alcohol at regular intervals.
Please cover dust cap after use and keep dust cap clean.
Please ensure power closed when cleaning. Please ensure laser source disabled when cleaning
any port, otherwise it
’
s possible to be inradiant danger.
Please connect device with matched optical fiber, otherwise unmatched connector may cause the
damage to output port.
Please take out the battery if you don’t use for long time.
Please put cotton swab with absolute ethyl alcohol in output port and gently spin, then change a
new one to clean once more.
