Additional Features: True Secondary-Transfer-Standard Performance 10 ppm rdg. + 1 ppm rng. Basic Accuracy 10 ppm Stability for 60 Days, 20 ppm for 6 Months “Incrematic™” Dial Control Over 2-Million Value EMF Reference Source 5-Decade Current Source NIST-Traceable on All Ranges μP-Based Design with Optional IEEE-488 Interface 1 ms Settling Time Full-Floating Output The Model 8200 is an extremely accurate microprocessor-based, remotely programmable, line-powered portable DC voltage/current standard. Transferring NIST reference values to instrumentation and equipment in the laboratory, the QA/QC department and on the production floor is convenient, fast and accurate. Six decade controls allow adjustment of accurate, ultra-stable DC voltage ranges of ±100 mV, ±10V, and ±100V, in steps of 0.1 µV, 10 µV, and 100 µV respectively, with 10 ppm basic accuracy. If an even wider range is called for, a 1 kV option is available. The Model 8200 also provides outputs from ±1 µA to ±100 mA as a DC current source, with 100 ppm basic accuracy.
