An instruments degree of repeatabilityhow reliably it can reproduce the same measurement over and over. Precision is a term that describes an instruments degree of freedom from random errors.

Precision instrument synonyms precision instrument pronunciation precision instrument translation English dictionary definition of precision instrument.
Precision of instrument definition. The precision has two characteristics. For example if you consider an analog scale which is set to graduate in divisions of 02 psi the position of the needle of the instrument could be estimated to be within 002 psi. PRECISION INSTRUMENT definition in the Cambridge English Dictionary.
An instrument or tool which is used for tasks which are precise or exact in nature Meaning pronunciation translations and examples. Or in other words it is the degree of agreement between repeated result. It is the ratio of change in output or response of the instrument to change in input or measured variable.
Precision It may be defined as the limits within which a signal can be read. Accuracy is the ability of the instrument to measure the accurate value and precision is a measure of the reproducibility of the measurements ie given a fixed value of quantity. In other words it is used in measurement for determining the consistency or the reproducibility of the result.
It is the measure of consistency or repeatability of measurements ie. Precision refers to the closeness of agreement between test results. Precision is often though incorrectly confused with accuracy.
Thus the precision of the instrument is 002 psi. The ISO definition means an accurate measurement has no systematic error and no random error. Essentially the ISO advises that accurate be used when a measurement is.
Long-term drift of an instrument affects precision only if it is considered over extended period of time The precision of an instrument is often not provided directly but it must be inferred from other. Precision describes the reproducibility of the measurement. If a large number of readings are taken of the same quantity by a high-precision instrument then the spread of readings will be very small.
The better the precision the lower the difference amongst the values showing that the results are highly reproducible. Precision refers to the repeatability of measuring process ie. In other words precision is the agreement among several determinations of the same quantity.
A tool that can be controlled very accurately so that it produces very accurate results 2. If a large number of readings are taken of the same quantity by a high-precision instrument then the spread of readings will be very small. Precision is a term used to describes an instruments degree of freedom from random errors.
Successive readings in an instrument should not differ. For example measure a steady state signal many times. The values do not have to be the true values just grouped together.
Precision is often although incorrectly confused with accuracy. Precisionwhich relates to the repeatability of the measurement is determined by noise and short-term drift of the instrument. Precision instrument n strumento di precisione.
The precision of an instrument indicates its ability to reproduce a certain reading with a given accuracy. In this case if the values are close together then it has a high degree of precision or repeatability. A higher sensitivity indicates that the system can respond to even the smallest input.
A tool that can be controlled very accurately so that it produces very accurate results 2.
