calibration

Calibration in measurement technology and metrology is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, or a physical artefact, such as a metre ruler.
The outcome of the comparison can result in no significant error being noted on the device under test, a significant error being noted but no adjustment made, or an adjustment made to correct the error to an acceptable level. Strictly, the term calibration means just the act of comparison, and does not include any subsequent adjustment.
The calibration standard is normally traceable to a national standard held by a National Metrological Institute.

    In the symphony of life, sometimes admitting you hit a sour note is the sweetest melody of growth.

    In the twisted realm of audio revelations, my stance on the whole timber-matching saga took an unexpected turn. Initially, I shrugged off the importance, relying on calibration voodoo for sonic cohesion. Yet, a recent sonic odyssey threw me into the abyss of dissonance, particularly during the...
