Do not use the tester if it is damaged. Inspect
the tester before use.
•
If this equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.

Caution
To avoid damaging the tester or cables under
test and to avoid data loss:
•
Always turn the tester off before removing or
installing a module.
•
Never connect the OTDR port to an optical
source. Doing so can damage the OTDR receiver.
•
Never connect the tester to an active network,
except when using the power meter. Doing so
causes unreliable test results and can disrupt
network operations.
•
If the tester shows an error because the power
reading is too high, immediately disconnect the
source from the tester. The tester is not
designed for measuring higher power levels,
such as produced by CATV, optical amplifiers,
and cellular systems.
•
Avoid touching reflective surfaces (such as
metal) to the end of a fiber cable plugged into
the OTDR when the OTDR is operating. An open
fiber connector endface has about a 4%
reflection. Holding a reflective surface near the
connector endface may cause much greater than
a 4% reflection, which may damage the
photodetector in the OTDR.
•
Use proper cleaning procedures to clean all fiber
connectors before every use. Neglecting this
step or using improper procedures can cause
unreliable test results and may permanently
damage the connectors.
•
Use a Fluke Networks FiberInspector Video
Microscope to periodically inspect the OTDR and
loss/length option’s OUTPUT connectors for
scratches and other damage.
•
Read the instructions for splice machines before
using the OTDR to monitor splicing procedures.
The OTDR can interfere with the light injection
detection techniques used by some splicers.
•
To avoid unreliable test results, connect the ac
adapter or replace the battery as soon as the
low battery indication appears.
