Fluke 742A Resistance Standards
Product overview: Fluke 742A Resistance Standards
High accuracy working standards for on-site resistance calibration
- 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
742A Resistance Standards are high accuracy working standards for precision, on-site resistance calibration. Their 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 742A Resistance Standards are small and rugged, they are 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.
The 742A-1 1 Ω and the 742A-10k 10 kΩ units are ideally suited for Artifact Calibration of 5700A/5720A Calibrators. The other values can be used to verify the calibration if you desire.
A convenient transit case, designed to hold two standards, is available as an option.
