Description

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 0.001&Omega, to 1M&Omega,. The resistor elements of the 0.001&Omega, to 1k&Omega, models (4 terminal construction) are of selected manganin wire, and those of the 100k&Omega, and 1M&Omega, models (3-terminal construction), nickel and chromium wire. AH resistors are fully processed to assure the permanence of resistance. Low- to high-value resistance standards - 0.001&Omega, to 1M&Omega, in 10 steps Calibrated limit of error - ±10 ppm to ± 100 ppm Suitable for precision DC measurements using a potentiometer or bridge
