This section applies to power meters with large area detectors and
screw-on interchangeable optical adaptors.
To access the optical connector, grasp the grey cover on the top of
the instrument and tilt it back. The cover can then be pushed back to
form a convenient tilt bail for the instrument.
To remove the fitted adaptor, simply unscrew it.
Different styles of standard and optional connector adaptors can be
easily fitted by the user.
CAUTION! Be careful of the optical detector when the connector
adaptor is removed. It is vulnerable to damage by static electricity, or
damage to the exposed detector cover glass.
CAUTION! Ensure that inserted connectors do not project through the
adaptor and push on the glass detector cover, or instrument damage
will occur.
These meters can be used with low-precision bare fiber adaptors.
CAUTION! Do not scratch the detector lens with glass fiber end when
using bare fiber adaptors, otherwise instrument will be permanently
damaged.
How to clean the optical connectors
Always clean the mating connector tip and ferrule before mating, using
approved materials.
CAUTION! Never use abrasive cleaners or permanent detector
damage may occur.
This port can be used with both PC and APC connector styles
The power meter interface does not make contact with the inserted
connector; there is a slight air gap. Therefore, it will not wear and only
needs occasional cleaning.
To clean:

Unscrew the connector adaptor, then use a soft brush,
alcohol, air can, or ‘Blu Tac‘ to clean the glass interface, and
inspect for cleanliness.

Using compressed air, blow out the hole in the connector
adaptor, and inspect for cleanliness.
Note: POF users may need to enlarge the connector exit hole on some
connector adaptors that were not specifically designed for POF usage.
If this hole is too small, measured powers will be low.
