Calibration \Cal`ibra"*tion\, n. The process of estimating the caliber a tube, as of a thermometer tube, in order to graduate it to a scale of degrees; also, more generally, the determination of the true value of the spaces in any graduated instrument.

Douglas Harper's Etymology Dictionary

1854, noun of action from calibrate.


n. The act of calibrate something.


n. the act of checking or adjusting (by comparison with a standard) the accuracy of a measuring instrument; "the thermometer needed calibration" [syn: standardization, standardisation]


Calibration is the process of finding a relationship between two quantities that are unknown (when the measurable quantities are not given a particular value for the amount considered or found a standard for the quantity). When one of quantity is known, which is made or set with one device, another measurement is made as similar way as possible with the first device using a second device.The measurable quantities may differ in two devices which are equivalent. The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.

The formal definition of calibration by the International Bureau of Weights and Measures is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication."

Calibration (statistics)

There are two main uses of the term calibration in statistics that denote special types of statistical inference problems. Thus "calibration" can mean

:*A reverse process to regression, where instead of a future dependent variable being predicted from known explanatory variables, a known observation of the dependent variables is used to predict a corresponding explanatory variable.

:*Procedures in statistical classification to determine class membership probabilities which assess the uncertainty of a given new observation belonging to each of the already established classes. In addition, "calibration" is used in statistics with the usual general meaning of calibration. For example, model calibration can be also used to refer to Bayesian inference about the value of a model's parameters, given some data set, or more generally to any type of fitting of a statistical model.

Calibration (Is Pushing Luck and Key Too Far)

Calibration (Is Pushing Luck and Key Too Far) is the fifth studio album by Omar Rodríguez-López, and the fourth released in the "Amsterdam series". The album was released in Japan on December 15, 2007 with a following U.S. release later on February 5, 2008, merely a week after The Mars Volta's The Bedlam in Goliath. The album art was illustrated by graffiti artist GREY, a childhood friend of Rodriguez-Lopez's. According to the label, the original title given to them by Omar was "Calibration Is Pushing Luck and Key Too Far" but the "Is Pushing Luck and Key Too Far" part of the title appeared nowhere on the physical release.

Usage examples of "calibration".

After three months of testing and calibration, INTELSAT 707 was nudged into its geostationary orbit high above the tiny West African island nation of Sao Tome and Principe.

It requires calibrations to be made against higher harmonics of very low frequency sounds, where the higher harmonics are in the range of the intervals that you are calibrating against.

The main reason to doubt that this type of arithmetic plays a significant role in the calibration of interval perception is the same as the second reason given above for supposing that higher harmonics are not involved in this calibration: complex fractions are not observed to be significant in music perception.

The first type of calibration would involve the human ear, nervous system and auditory cortex all being pre-programmed to grow and develop in such a way that the intervals between different pairs of pitch values whose frequencies are in the same ratios are perceived as the same intervals.

The high-energy proton spectrpmetry clusters flunked out, too, as did the gravimetric distortion mapping scanner, the fixed angle gamma frequency counter, the wide-angle EM radiation imaging scanner, the quark population analysis counter, the Z-range particulate spectrometry sensor, the low-frequency EM flux sensor, the localized subspace field stress sensor, the parametric subspace field stress sensor, the hydrogen-filter subspace flux scanner, the linear calibration subspace flux sensor, the variable band optical imagining cluster, the virtual aperture graviton flux spectrometer, the high-resolution graviton flux spectrometer, the very low energy graviton spin pola-rimeter, the passive imaging gamma interferometry sensor, the low-level imagining sensor, the virtual particle mapping camera, and even the life-form analysis instrument counter.

The calibration is critical, so we have to have people with both maintenance and operational experience.

From his comments, Krishia deduced that the first blast was for calibration purposes only.

He occupied himself with repeating systems checks and performing useless calibrations, wishing he'd at least thought to bring along a magazine, or his VR headset.

To further this delicious calibration he slightly bent and parted his legs, urging himself forward half a famished millimetre.
