Place an insulating support (height 0.1 m) on the ground plane, and place the EUT on top of it for testing.

When using a coupling adapter, do not take the EUT power supply through the impulse noise tester; take it independently from the primary side.
Also, when testing power lines, do not connect the coupling adapter to the impulse noise tester.
