VI. Testing Mode
6.1 Testing Twisted-Pair Cabling
6.1.1 Cabling Test
(1) Turn on the tester, and set the knob to "TEST", then press "PORT" to select RJ45
port.
(2) Connect tester and wiremap adapter to the cabling, the test runs continuously until
you change modes or turn the tester off.
Note: Accurate cable length measurement without the need to connect a remote adapter,
however, an adapter is required for a complete wiremap test.

6.1.2 Typical Testing Results
6.1.2.1 Open on Twisted Pair Cabling
As shown in figure 6.2, the third wire is open-circuit, the three segments shown for the wire
pair length indicate the open is approximately 3/4 the distance to the end of the cabling.
The cable length is 71.5m.
To see the distance to the open, use "
" and "
Note: If only one wire in a pair is open, both wires are shown as open. The warning icon
"
" does not appear if both wires in a pair are open because open pairs are normal for
some cabling applications.
