Care and Maintenance
1.
Keep the sensor port clean from pollution; not use dirty and non-standard
fiber-optic adapter connector; not to be inserted to the badly-polished port. Otherwise
the sensor port can be damaged and the whole system performance will be affected.
2.
Insist on the use of one fiber-optic adapter as possible.
3.
Once the instrument is not used, cover it with dust cap to keep the port clean
