Definitions and Conditions Specifications describe the performance of parameters covered by the product warranty and apply to temperature ranges 0 to 55 °C 1, unless otherwise noted. 95th percentile values indicate the breadth of the population (approx. 2 σ) of performance tolerances expected to be met in 95 percent of the cases with a 95 percent confidence, for any ambient temperature in the range of 20 to 30 °C. In addition to the statistical observations of a sample of instruments, these values include the effects of the uncertainties of external calibration references. These values are...
