4-wire connections
Connections for 4-wire local sensing are shown in Figure 4. Use 4-wire remote sensing for
the following source-measure conditions:
•
Test circuit impedance is <1k
Ω
.
•
Optimum ohms, V-source, and/or V-measure accuracy is required.
With 4-wire sensing selected, the 4W annunciator is on. The following menu sequence
selects 4-wire remote sensing:
Press CONFIG > select SOURCE V (or MEAS
Ω
) > select SENSE MODE > select 4-WIRE
NOTE
Specified accuracies for both source and measure are achieved only using 4-wire
remote sensing.
