Standard 742A-25
The 742A-25 is a used Resistance Standard from Fluke. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers. Additional Features: Small and rugged resistance calibrators No oil or air baths required 18° to 28° C operating range Six-month stability to 2.5 ppm Supplied with temperature characterization The Fluke 742A-25 Resistance Standard is a high accuracy working standard for precision, on-site resistance calibration. Its excellent temperature stability allows them to be used from 18°C to 28°C with typically less than 2 ppm degradation. Using the calibration table supplied with the standards, which lists corrections in 0.5°C increments, this uncertainty can be reduced to near zero. No cumbersome oil or air baths are required. Because the Fluke 742A-25 Resistance Standard is small and rugged, it is easy to transport. Care has been taken to reduce resistance changes brought about by thermal and mechanical shock. Retrace (permanent shift in resistance) is typically less than 2 ppm after cycling between 0°C and 40°C.
