Resistance decade box 3000RS

precision

PRECISION REFERENCES AND STANDARDS • Decade resistances from 1 Ohm to 10MOhm • Temperature co-efficients as low as 0.1ppm/°C • Annual stabilities of better than 5ppm • Precision decade resistance reference The 3000RS is a modern precision resistance standard offering annual stabilities of better than 5ppm without the requirement for an oil bath, with temperature co-efficients as low as 0.1ppm/°C Using ultra-high precision, 4 wire hermetically sealed oil filled film resistors for values from 1 Ohm through to 100 kOhm, and oil filled precision wire wound resistors for the 1 MOhm and 10 MOhm, the 3000RS is suitable for roles of both a working secondary set of resistors or a primary resistance reference. Using the 3000RS with the 8500 low thermal scanner provides an automated solution for the calibration of precision multimeters.
