Annex A Cleaning the optical output port

Pay attention to the following when operating the instrument:
Keep the optical output port clean, and clean it regularly with absolute ethyl alcohol.
Cover the instrument with the dust cap after operation, and keep the dust cap clean.
Clean regularly the ring flange connector at the optical output port. In case of any crack or
breakage to the ceramic core in the ring flange, replace the ring flange in time.
Reasons for cleaning the optical fiber connector and optical output port are as follows:
Since the optical fiber core is very small, any dust or particle adhering to the optical fiber
connector and optical output port can cover part of the optical fiber core at the output end,
resulting in instrument performance reduction.
Such dust or particle can wear the end face of the optical fiber connector at the output end,
affecting the test accuracy and repeatability of the instrument.
Follow the safety precautions first before cleaning:
Make sure the power supply of the instrument is cut off.
Failing to follow relevant control, adjustment or operation procedures can result in dangerous
radiation injury.
Make sure to disable the optical source when cleaning any optical port.
Do not look straight at any optical output port, so as to avoid any eye injury when the
instrument is in operation.
