Keysight Technologies Reliable High-Resistance Measurements Using the B2985A/87A Electrometer/High Resistance Meter 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
