Unless otherwise specified by customer, methods used are those stipulated by NIST Handbook 44 N.1.1, N.1.2, N.1.3 and N.1.9. The calibrations within the report are traceable through NIST or another NMI to the SI units and apply to the item as received. Best estimate of uncertainty is in compliance with a 3 to 1 ratio (See NIST Handbook 44, Appendix A, Section 3.21). The reported expanded uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the coverage factor k=2 such that the coverage probability corresponds to approximately 95%. Acceptable environmental operating range is 14°F to 104°F and 28 in. Hg to 31 in. Hg with any deviations noted.
