> **Understanding "Delta Mode":** The term "Delta Mode" refers specifically to a technique used by Keithley Models 6220 and 6221 Current Sources in conjunction with the Model 2182A Nanovoltmeter for very low resistance measurements. This method is described in detail in the [Keithley Low Level Measurements Handbook](https://www.tek.com/en/documents/product-article/keithley-low-level-measurements-handbook---7th-edition). In this documentation, "Ultra Low Resistance Measurements" is used as the general scientific term, while "Delta Mode" may appear when specifically referencing the Keithley-specific method or program files.
