Warning
To avoid possible fire, electric shock, personal
injury, or damage to the tester:
• Do not open the case. No user-serviceable parts
are inside.
• Replacing electrical parts yourself will void the
tester's warranty and might compromise its
safety features.
• Use only specified replacement parts for user-
replaceable items.
• Use only Fluke Networks authorized service
centers.
Caution
Replacing electrical parts yourself might void
the tester's calibration and compromise its
accuracy. If the calibration is void, cable
manufacturers might not extend their warranty
to the cabling you install.
Reference Procedure for Link Interface Adapters
The reference procedure sets a baseline for insertion loss,
ELFEXT, and dc resistance measurements. You should
perform the reference procedure every 30 days or
whenever you start using the tester with a different
remote.
See “Setting the Reference” in Chapter 3 for details.
