If the EUT isn't grounded, and very solidly grounded at that, the permittivity of the insulator may affect the results, since it affects the capacitance of the EUT to ground, in parallel with the inductance of the grounding strap. So the inch/cm-worms should measure the permittivity with a microfaradpermeter as well as the thickness.(;-) -- OOO - Own Opinions Only.
