Replacing Reference Test Cords and Launch Fibers
Choose replacement reference test cords and launch and
receive fibers that meet the following requirements:
•
•
•
•
To ensure optimum performance from your tester, get
replacement reference test cords and launch fibers from
Fluke Networks.
Replacing the Battery
Replace the lithium ion battery pack when its life becomes
noticeably shorter. The battery is normally good for up to
400 charge/discharge cycles.
An internal lithium battery maintains the tester’s clock and
other settings when you remove the battery pack. This
battery typically lasts about 5 years. When the battery

Core and cladding size: match the fiber to be tested
Connector polish: UPC for reference test cords and
launch fibers
Reference test cord length: minimum 2 m; maximum
5 m
Launch and receive fiber length: 100 m minimum for
multimode; 130 m minimum for singlemode
Dispose of the lithium ion battery pack in
accordance with local regulations.

Note
begins to fail, the tester will lose the current date and time
when you remove the battery pack. If the lithium battery
fails, send the tester to a Fluke Networks service center for a

•
To avoid damaging the display or the case, do not
use solvents or abrasive cleansers.
Before storing the tester or an extra battery for an
extended period, charge the battery to between
70 % and 90 % of full charge (2 or 3 LEDs lit on the
battery’s gauge). Check the battery every 4 months and
recharge if necessary.
Keep a battery attached to the tester during storage.
Removing the battery for long periods shortens the life
of the lithium battery that maintains the clock.
See “Environmental and Regulatory Specifications” on
page 11-10 for storage temperatures.
