You can use either the front-panel or the rear-panel terminals for this application. The following
figures show the physical connections for the front and rear panels. Note that you must use either the
front-panel terminals or rear-panel terminals — you cannot mix connections.
When you connect the leads to the device under test (DUT), notice that the FORCE LO and SENSE
LO connections are attached to one of the DUT leads. Make the FORCE HI and SENSE HI
connections to the other lead. Connect the sense connections as close to the resistor under test as
possible. This 4-wire measurement eliminates the resistance of the test leads in the measurement.
The figure below shows the front-panel connections. You can make these connections with four
insulated banana cables that are rated to the maximum current (7 A) such as two sets of the Keithley
Instruments Model 8608 High-Performance Clip Lead Set.

The figure below shows the rear-panel connections. You can make these connections with either the
Model 2460-KIT Screw-Terminal Connector Kit (included with the Model 2460) or a Model 2460-BAN
Banana Test Leads/Adapter Cable with appropriate cabling.
