# Standard Resistors 2792A

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. AH resistors are fully processed to assure the permanence of resistance.

• Low- to high-value resistors standards - 0.001Ω to 1MΩ in 10 steps
• Calibrated limit of error - ±10 ppm to ± 100 ppm
• Suitable for precision DC measurements using a potentiometer or bridge
• Testing resistors yields accuracy of ±5 ppm
