Fiber Test Module Maintenance
The following sections apply to the optional DTX-MFM
and DTX-SFM fiber modules.
Optical Connector and Adapter Care
Periodically clean and inspect the module’s optical
connectors as described in Chapter 5.
Replacing Fiber Patch Cords
Choose replacement fiber optic patch cords that meet the
following requirements:
• Core and cladding size: match the fiber to be tested
• Connector polish: PC or UPC
• Patch cord length: minimum 2 m; maximum 5 m
To ensure optimum performance from your tester, get
replacement patch cords from Fluke Networks.
Storage
• Before storing the tester or an extra battery for an
extended period, charge the battery to between
70 % and 90 % of full charge. 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 internal lithium battery that maintains the
clock.
• See “Environmental and Regulatory Specifications”
on page 9-14 for storage temperatures.
If Something Seems Wrong
If something seems wrong with the tester, refer to
Table 9-1.
If Table 9-1 does not help you solve a problem with the
tester, contact Fluke Networks for additional help. See
Chapter 1 for contact information.
If possible, have the tester’s serial number, software and
hardware versions, and calibration date available. To see
this information, turn the rotary switch to SPECIAL
FUNCTIONS; then select Version Information.
