Accuracy, precision, and resolution are three distinct but related concepts in the context of process instrumentation. Accuracy refers to how close a measurement is to the true value of the quantity being measured. A highly accurate instrument provides measurements that are close to the actual value, with minimal systematic error. Systematic error is a consistent error that always occurs in the same direction. For example, a temperature sensor that consistently reads 2 degrees Celsius higher than the actual temperature has a system....
