Set Reference
To exclude the length measurement of patch cables, you can use
Set Reference
to
determine the length of these cables and have the device automatically subtract them
from the total length of the cable test.

Tests can be carried out on cables with or without the use of patch cables,
depending on the type of cable termination being used.
Cable tests are typically performed with patch cables in order to test through a patch
panel or keystone jack. Set reference is carried out as explained under "Set the
reference with leader cables". If no patch cable is being used, "Set Reference" is used
to calibrate the length measurement at the connector.
Follow the instructions on the screen to define and save the length of the patch cable.
Be sure to connect the patch cable to the main unit only, do not connect the other end
of the patch cable to the remote or networking equipment.
Select
Set Reference
to
calibrate the patch cable length or NetXpert XG2 connector
capacitance (pF), which will later be subtracted from cable test length measurements. The
referencing procedure should be repeated when changing patch cables.
