Fluke.Keeping your worldup and running.

Fluke measurementspecification philosophyThe accuracy specifications for theFluke 2680 Series, Hydra Series,and NetDAQ Series instruments arecalculated conservatively so thatthey include three standard devia-tions from the nominal value—thisis referred to as 3-Sigma. Morethan 99.7 % of the instrumentsproduced will perform within theerror limits. Rigorous screeningand testing procedures catch andcorrect the three out of 1,000instruments which could havefallen outside their publishedspecifications.

Many other products use a“rootsum-square” scheme, or onlyspecify the error band within onestandard deviation (1-Sigma) ofnominal. This method produces aspecification that appears to bemore accurate, but the resulting“typical” specifications correctlycharacterize only ~66 % of theinstruments produced. Thismethod is kind of like knowinghow accurate “most of the instru-ments” will be. The 3-Sigma spec-ifications for the 2680 Series,Hydra, and NetDAQ tell you howaccurate ALL of the instrumentswill be.Note: Listed specifications aresummary in nature.
