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:
 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.
To set the reference
1 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).
2 Use the reference patch cord and two channel adapters or
permanent link and channel adapters to connect the main
and remote testers together as shown in Figure 10.
