Technical Overview
Introduction
Previously, high resistance and resistivity measurements have required exten-
sive measurement expertise in order to obtain accurate results. This is Important words used in
primarily due to the nature of very low current measurements, which are ex- the document:
tremely sensitive to a variety of environmental factors. Typical sources of error
Preix in the metric system used
include: leakage currents, discharge or absorption currents, test device ground-
in very low current:
ing/loating issues, and environmental noise arising from the test device's
