Precision And Accuracy 1 Pdf Accuracy And Precision Measurement What is suitable traceability according to the law the need for meter standards and traceability in electric metering the definition of metrology and the application of this science in electric metering the difference between accuracy and precision and why both are important the use of standards in the test lab the use of portable standards in. 1.1.1 introduction to metrology metrology word is derived from two greek words such as metro which means measurement and logy which means science. metrology is the science of precision measurement. the engineer can say it is the science of measurement of lengths and angles and all related quantities like width, depth, diameter and straightness with high accuracy. metrology demands pure. In order to achieve this greater precision measuring equipment of a greater accuracy and sensitivity must be used. micrometer is one of the most common and most popular forms of measuring instrument for precise measurement with 0.01 mm accuracy. The precision of a measurement system, re lated to reproducibility and repeatability, is the degree to which repeated measurements under unchanged condi tions show the same results.[1][2] although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method.
