Section 5: Measuring low-resistance devices Model 2450 SourceMeter® Instrument User's Manual
Turn the power to the instrument off before attaching connections to the 2450.
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, such as two sets of the Keithley Instruments Model 8608 High-Performance
Clip Lead Set.

triaxial cables.
