Keithley 2016 - Shielding; Figure 2-6 Two- and Four- Wire Resistance Measurements

Shielding
To achieve a stable reading, it helps to shield resistances greater than 100kΩ. Place the
resistance 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.
