JK2830 Operation Manual Chapter 5 Execute LCR operation and some examples

measurement result will have errors. If a ground conductor is installed between
high and low terminals, Cd can be reduced to Min. Meanwhile if the ground
terminal is connected to the conductance plate, the influence of Ch and Cl will be
eliminated.
When the DUT is low impedance (such as small inductance, large capacitance), a
large current will flow through test leads Hc and Lc. In this case,

electromagnetic coupling between test leads becomes the main source
of test errors

except the influence of the contact resistance on test terminals. If

this  coupling  cannot  be  eliminated,  it  will  bring  unexpected  influence  on  test
results.  Generally,  contact  resistance  affects  the  resistance  of  impedance  and
electromagnetic affects  the reactance  of  impedance. Test terminals  can  adopt
4TP connection method. For 4TP connection, the currents flow though Hc and Lc
are  equal  in  value  and  opposite  in  direction  with  those  flowing  through  each
shielding terminals. By this way, the magnetic fields produced by these currents
can be mutually offset and further eliminate the influence of mutual inductance
coupling on test results.
