Calibration refers to the process of determining the relation between the output (or response) of a measuring instrument and the value of the input quantity or attribute, a measurement standard. In non-specialized use, calibration is often regarded as including the process of adjusting the output or indication on a measurement instrument to agree with the value of the applied standard, within a specified accuracy. For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted (e.g. via calibration constants) so that it shows the true temperature in Celsius at specific points on the scale.

Generally Calibration term used with the measuring instruments, for example I am having liter measuring flask and I measured I liter of water, Who will assure that instrument you are using is measuring correct. Here comes the Calibration of the instrument, which certifies that whatever is measured is accurate or not.if not then what is the error percentage.

Calibration is adjustment of instrumentation using some measurement standard, in order to keep it functioning as accurately as possible.

Calibration is the process of testing and readjusting usually a measuring instrument so that it produces precise measurements.Usually a defective instrument is used to measure a piece of known measure and adjusted until its reading is the same with the piece's known measure.

i dont know the official definitions but i can explain what they are calibration is basically setting the measuring intrument right, so you will zero it at the zero postion or set a number to mean something by reference to a known value for example if you where calibrating a set of scales when there was nothing on them youl would 'zero' them so that nothing gives a reading of zero, or if you where calibrating a digital spirit level you would lay it on something you know is flat and then it that its at zero degrees validity in your isa something will be valid if it is reliable and can be repeated and measure what its supposed to measure if you get your gcse text book, there will be a 'how science works' section and the official definitions will be in there

I recently found out about this site about calibration of instruments and found the information fully detailed and very easy to understand. i'm sure it would be very helpful for you.

In science and engineering the SI system is popular and has exact standards. An instrument can be adjusted so that it matches the standards.

when machines is working they gragually lost thire exactness . readjustment means calibration.
