| Fluke 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 degree C to 28degree C with
typically less than 2 ppm degradation. Using the calibration table supplied with
the standards, which lists corrections in 0.5degree 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 0degreeC and 40degree C. The 742A-1 1 Ω and the 742A-10k 10 kΩ units are ideally suited for Artifact Calibration of Fluke 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.
