3000RS Precision Resistance Standard

Description

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, it is suitable for roles as either 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 calibration of precision multimeters.
