Figures 2-2 through 2-4 illustrate various methods of connection to the device under test
(DUT). Figure 2-2 illustrates the two-wire connection to DUT. The two-wire ungrounded
connection is the recommended connection of ungrounded components or components
that can be connected very close to the 2408 input terminals rather than through the lead
set provided.
Figure 2-2: Two-Wire Ungrounded Connection
The two-wire grounded measurement is a common type of connection to be used on the
2408. This is the recommended connection on grounded components or components that
are some physical distance from the input terminals of the unit. A grounded component is
one in which one of its connections goes to an earth ground, whereas on an ungrounded
component neither connection goes to earth ground. A component being measured with a
lead set is considered to be a physical distance away from the terminals and thus the two-
wire grounded connection is often recommended.
