Keithley 2000 - Two- and Four-Wire Resistance Measurements

Shielding
To achieve a stable reading, it helps to shield resistances greater than 100kΩ. Place the resis-
tance in a shielded enclosure and connect the shield to the INPUT LO terminal of the instrument
electrically.
See Section 3—Measurement Options for information that explains the configuration options
for 2-wire and 4-wire resistance measurements.
