742A RESISTANCE STANDARD

High accuracy working standards for on-site resistance calibration.

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.
