SMU Kelvin leakage test
When a Model 2410 SMU is in your system (high-voltage systems only), only row pair A and B will be
tested by the 2410. The remaining rows will be tested using the Series 2600A instruments. Systems
without a Model 2410 will test rows A through H using the Series 2600A instruments.

Force test
During the leakage test, SMUs are used in the 2W mode. The test flow is the same as the instrument
card 2W tests.
Sense test
During the leakage test, SMUs are used in 4W mode. The sense terminal is used to connect the two
SMUs.
