About Setting The Reference - Fluke DTX-MFM2 User Manual

Connector Ends
1 Touch the tip of a fiber optic solvent pen or swab
soaked in solvent to a lint-free dry wipe or fiber
cleaning card.
2 Wipe the connector end-face across the solvent spot,
then back and forth once across the dry area of the
wipe or card.
Some connector styles, such as VF-45, may require
a different cleaning method.
3 Inspect connectors with a fiber microscope, such as the
Fluke Networks FiberInspector Video Microscope
before making connections.
Always cover unused connectors with protective caps. Clean
caps periodically with a swab or wipe and fiber optic
solvent.

About Setting the Reference

The reference serves as the baseline power level for loss
measurements. Regular referencing helps account for
minor variations in source power and connection integrity.
Also, since the reference is the baseline for measurements,
the losses of the test reference cords and adapters used
during referencing are excluded from test results.

Note
Turn on the tester and smart remote and let them
sit for 5 minutes before setting the reference.
Allow additional time if the modules have been
stored above or below ambient temperature.
You should set the reference at these times:
•
At the beginning of each day using the remote end
setup (Figures 10 through 18) you will use that day.
•
Anytime you reconnect a test reference cord to the
module's output or other source.
•
Anytime the tester warns you that the reference is out
of date.
•
Anytime you see a negative loss measurement. (See
the Technical Reference Handbook for more
information.)
You must set the reference at these times:
•
Anytime you change the fiber module in the tester or
smart remote.
