Set the Reference
The reference procedure for twisted pair cable sets the baseline
for insertion loss, ACR-F, and DC resistance measurements.
Set the reference at these times:
 When you want to use the tester with a different module. The
tester can save reference values for eight different pairs of
modules.
 When you attach Class F/F
A
link interface adapters, such as the
optional DSX-PLA011 TERA ™ adapters.

Every 30 days, at minimum. To ensure maximum accuracy of
test results, set the reference daily.
It is not necessary to set the reference when you change the link
interface adapters (unless you attach Class F/F
A
link interface
adapters).
To set the reference
1
Install DSX modules in the tester and the remote.
2
Turn on the tester and the remote a minimum of 5 minutes
before you set the reference.
Note
Set the reference only after the testers are at an
ambient temperature between 50 °F and 104 °F
(10 °C and 40 °C).
3
Use the appropriate adapters or a reference artifact to
connect the main and remote testers together as shown in
Figure 27.
