Connecting a DUT
2-Wire Connections or 4-Wire Connections
When connecting a DUT, you can choose the connection type either 2-wire
connections or 4-wire connections.
If you want to simplify the connections, use 2-wire connections by connecting the
Force terminals only and opening the Sense terminals. The Force terminals can be
used to apply and measure DC voltage or current.
To make 4-wire connections, remote sensing, well known as Kelvin connections,
use both Force and Sense terminals. Connecting the Force and Sense lines together
at the terminal of the DUT minimizes the measurement error caused by the residual
resistance of the test leads or cables. This connection is effective for low resistance
measurements and high current measurements.
To specify the connection type (Sensing Type), perform the following procedure.
1. Press the Config > Source > Connection function keys. This opens the Output
Connection dialog box.
2. Set the Sensing Type on this dialog box. Choose 2-WIRE for 2-wire
connections, or 4-WIRE for 4-wire connections.
3. Press the OK softkey. For 4-wire connections, the following indicator appears
on the Single view or the Dual view.
