Non-Kelvin Measurement
Click
Remove the jumper lead connected between the terminal 17 and the SMU4 F terminal. And click the
Append button to add another measurement to the graph.
Now you see the very large difference between Kelvin and non-Kelvin measurements when the
resistance is low. You can see that Re jumps from about 0.735 ohm in this example, to about 0.949
ohm. The extra resistance is due to cable loss and fixture loss. This resistance is compensated out
when you use the Kelvin connection.
