Model 2792A resistors are low- to high-value resistance standards which can be used for accurate DC measurements in combination with a potentiometer or bridge. The different models are available, ranging from 0.001Ω to 1MΩ. The resistor elements of the 0.001Ω to 1kΩ models (4 terminal construction) are of selected manganin wire, and those of the 100kΩ and 1MΩ models (3-terminal construction), nickel and chromium wire.
