Cleaning Instructions
Preserving Connectors
Listed below are some hints on how best to keep your connectors in the
best possible condition.
Making Connections Before you make any connection you must
ensure that all cables and connectors are clean. If they are dirty, use the
appropriate cleaning procedure.
When inserting the ferrule of a patchcord into a connector or an adapter,
make sure that the fiber end does not touch the outside of the mating
connector or adapter. Otherwise you will rub the fiber end against an
unsuitable surface, producing scratches and dirt deposits on the surface of
your fiber.
Dust Caps and Shutter Caps Be careful when replacing dust caps after
use. Do not press the bottom of the cap onto the fiber as any dust in the
cap can scratch or dirty your fiber surface.
When you have finished cleaning, put the dust cap back on, or close the
shutter cap if the equipment is not going to be used immediately.
Keep the caps on the equipment always when it is not in use.
All of Keysight Technologies' lightwave instruments and accessories are
shipped with either laser shutter caps or dust caps. If you need additional
or replacement dust caps, contact your nearest Keysight Technologies
Sales/Service Office.
Immersion Oil and Other Index Matching Compounds Where it is
possible, do not use immersion oil or other index matching compounds
with your device. They are liable to impair and dirty the surface of the
device. In addition, the characteristics of your device can be changed and
your measurement results affected.
Cleaning Instrument Housings
Use a dry and very soft cotton tissue to clean the instrument housing and
the keypad. Do not open the instruments as there is a danger of electric
shock, or electrostatic discharge. Opening the instrument can cause
damage to sensitive components, and in addition your warranty will be
voided.
