Difference between accuracy and precision

Accuracy “Accuracy gauges how closely results match the real or predetermined value” Precision “Precision assesses how closely related outcomes are to one another” Comparison Chart between Accuracy & precision  Basis for Comparison Accuracy Precision Meaning Accuracy refers to the degree of agreement between the absolute measurement and the actual measurement. Precision refers to the degree of variance present in the results of multiple measurements of the same factor.  Represents How Closely result agree …

Different types of calibration

Definition and Need for Calibration According to Webster’s Dictionary, calibrate means “to check, adjust, or standardize systematically the graduations of a quantitative measuring instrument.” As noted in Inter-Range Instrumentation Group (IRIG) 118-98 Volume I, “a telemetry system measurement begins with the sensing of a measurand by a transducer located either on a test vehicle or …
