4. Maintenance
4.1
Keep the sensors’ surfaces clean and free of dust or other contaminant
by cleaning them regularly.
4. 2
Do not use unclean or nonstandard adapters.
4.3
Change adapter carefully if necessary and keep any spare adapter in
dirt/dust free environment.
4.4
When the instrument is not in use, keep the optical connectors covered
with dust caps at all the time. Exposing the sensor for a long period of time
will allow dust to be accumulated on surface of the sensor; this will in turn
result in measurement inaccuracy.
4.5
Consider leaving test cords connected to the PON meter at all times.
This will prolong the life of the instrument ONT & OLT connectors.
