Four-Terminal Pair Configuration
2. The vector voltmeter measures the differential voltage between the inner

and same amount current flow. Hence there is little inductive magnetic
field, test leads do not contribute additional errors due to self or mutual
inductance between the individual leads.
and outer conductors. The differential measurement method can minimize
the influence of the mutual inductance.
