In addition, the shielded cable under test may not be equipped with an socket or plug. In this
case, connecting the main unit with a shielded patch cord will not provide the cable shield contact
with the grounding contact ST 301.
For connection of the shield it is necessary to use a patch cord with a probe needle
(Fig.1, item
22)
equipped with a probe needle. This needle punctures the isolation of the tested cable and
provided contact with the shield.
The other end of this patch cord is equipped with a jack that connects to the "SHIELD" slot of
the main unit.
The scheme of connection to shielded cable (which no equipped with socket and plug) using
the adapter
(Fig.1, item 16)
and a patch cord with a probe needle is shown in Fig.9.

The cable is connected directly to the "INPUT" slot of the main unit. The contact with the cable
shield is provided by means of the patch cord with the probe needle
(Fig.1, item 22)
