Effect of Eddy Currents
Appx. 2 Effect of Eddy Currents
The AC current generated in the instrument induces eddy currents in the
surrounding metallic plates, which generate induced voltage in the test lead.

measure resistance using an AC source. To protect the test lead from such
effects, keep metallic parts, including metallic plates, at a suitable distance
from the test lead (branched section).
