Assuming that you are asking why is there a need, the reason is simple. At any given point a machine, especially precision machines, are moving in their operation. Calibration ensures that the machine works to factory specification, thus making the machine run smoothly. Calibration is necessary because in the normal operation, the parts move ever so slightly with each motion, taking it out of perfect alighnment. Recalibration corrects the problem of sloppy performance. Assuming that you are asking why is there a need, the reason is simple. Every time a measurement is made or a process is performed, there is an actual result and an expected result. Because of random and non-random variability, the actual result usually differs from the expected result. Calibration works to either fix the non-random variability or account for it in such a way that the difference between the actual and expected results are random and negligible. Often a calibration is used with a control scheme which monitors process variability and makes corrections or applies calibrations to ensure the quality of the product.

What is the basic calibration process?
The Basic Calibration Process is the process through which an instrument is calibrated, or set to a scale, during its manufacturing process - and it must be able to "hold a calibration."
When calibration required?
Calibration is required during installation of new instrument to check whether the instrument works as per specifications or not. Calibration is required when instrument is shifted from one location to another. Calibration of instrument is done when instrument is used again after maintenance. Some instruments such as weighing balance are calibrated daily while some instruments or equipments such as HPLC, GC, etc., are calibrated or validated at specified interval as per standard operating procedure (SOP).
What is sensor calibration?
calibration of sensors to optimize sensor accuracy
What are the precautions to be taken while using UV spectrophotometer?
One should not touch the optical assembly with bear hands. Optical surface of cuvettes should not be touched with fingers to avoid erratic reading. Always ensure effectiveness of silica gel kept in instrument. Preserve the instrument from dust particles. Never wash the cuvettes with chromic acid. Wash the cuvette with the distilled water and then with methanol before storage. Check the calibration status before using the instrument and ensure the timely calibration. Do not overfill the cuvettes. Perform the visual inspection of cuvettes for suitability.
When are calibration standards used?
Calibration standards are used to record the accuracy of certain calibrations that are performed. The accuracy allows the user to find out how good the calibration was.
What is the calibration of an ammeter?
calibration of an ammeter is done in order to standardise the instrument,and rectify the errors present in the instrument, if any.
What is an absolute instrument?
An absolute instrument is an instrument whose calibration can be determined by means of physical measurements.
What is the calculation for the calibration of a Level instrument displacement type dry method?
How to find out the calculation for dry calibration of a level instrument used on the top of the tank? How to calibrate level instrument with the help of weights?
What is calibration of instrument?
To know about the error, quality, performance of every instrument calibration is an essential part. A standard calibrator is required for this process to calibrate that Instrument. That calibrator is also Calibrated and standardised by National or International Standard.
How do you detirmine the precision in an instrument?
By calibration in comparison to a standard one.
What is the basic calibration process?
The Basic Calibration Process is the process through which an instrument is calibrated, or set to a scale, during its manufacturing process - and it must be able to "hold a calibration."
Judgment criteria for whether an instrument needs calibration?
calibration criteria is depend on instrument. if u r 1st criteria is for 3 month and after 3 month instrument is properly working then second time you may be extended its for 6 month..

Why you use holmium filter for UV calibration?
to check the sensitivity of the instrument
What is the common formula used when checking equipment calibration?
sources used for instrument checking and calibration irradiation of other materials, and radiography called
CATLab accredited calibration lab?
CATLab is the A2LA Accredited Test Equipment Calibration division of Control Automation Technologies Corporation. CATLab has two laboratories, North Carolina and Virginia. It provides precision instrument calibration services for test equipment used by Electrcial, Quality and Instrument technicians.
What process is occurring when you change a test instrument's output to agree with a known standard?
Your answer is Calibration.
