The AT series testers provide all the connections required to take advantage of
Kelvin measurements.
A test node may be considered to be a pair of connections consisting of one

The following diagram indicates how to identify the node terminal function;
POWER terminals are all on the outside of the fixture area.
SENSE terminals are all on the inside of the fixture area.
IMPORTANT: Kelvin four terminal connections are generally advised to be
used in all test fixtures but they are essential for impedance measurements
