5.2 Attaching a Connector Adapter
A specialized connector adapter is required for connecting an optical connector to the instrument. Choose
an adapter that matches the optical connector you will use.
The screw mechanism that attaches the connector adapter to the instrument is of precision manufacture.
Please handle all parts with care so as not to damage the screw threads.
Do not allow dirt to come into contact with the optical input section. Dirt or other
foreign particles can influence measurement. Attach the protective cap to the
optical input connector when not in use.
(1) Remove the optical input connector cap.
(2) Attach a connector adapter.
The connector adapter screws onto the connector; hold the adapter upright to align
the threads properly, then turn to tighten.
Do not attach the connector adapter at an angle, and do not forcibly turn it any
further after it has initially tightened. Doing so can damage the screw threads or
sensor.
Note
It is recommended to clean the inside of the connector adapter using a dedicated
swab or other cleaner and anhydrous alcohol.
Dedicated swabs for cleaning optical adapters are available from NTT, including
the “CLETOP Stick-Type” (NTT-ME).
