Certifying Twisted Pair Cabling
Setting the Reference
The reference procedure sets a baseline for insertion loss,
ELFEXT, and dc resistance measurements.
Run the tester’s reference procedure at the following
times:
• When you want to use the tester with a different
smart remote. You can reference the tester to two
different smart remotes.
• Every 30 days. Doing so ensures maximum accuracy
of test results.
You do not need to set the reference after changing link
interface adapters.
Note
Turn on the tester and smart remote and let
them sit for 1 minute before setting the
reference. Set the reference only after the
testers have reached an ambient temperature
between 10
°
C and 40
°
C (50
°
F and 104
°
F).
