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.

What process is designed to ensure the accuracy of measurements through routine performance of a set of operations designed to detect and than correct errors in the measurement instrument?
calibration
Difference between calibration and validation?
A calibration is a process that compares a known (the standard) against an unknown (the customer's device). During the calibration process, the offset between these two devices is quantified and the customer's device is adjusted back into tolerance (if possible). A true calibration usually contains both "as found" and "as left" data. A validation is a detailed process of confirming that the instrument is installed correctly, that it is operating effectively, and that it is performing without error. Because a validation must test all three of these operational parameters, it is broken into three different tests: the installation qualification (IQ), the operational qualification (OQ), and the performance qualification (PQ).
How do you decide calibration frequency for instruments?
Normally it will get from its instruction manual. In most of the engineering concerns there will have a calibration schedule for calibration of measuring instruments. The frequency of calibration mainly depend on the type nature and usage of such instruments.
What is a wrongly calibrated instrument?
A wrongly calibrated instrument is one that shows the wrong measurement. For example, alcohol in a thermometer rises with temperature; but the exact marks for 0 degrees, 10 degrees, ... 100 degrees (for example) may be wrongly placed, so that, when the temperature really is 30 degrees, the thermometer only shows 28 degrees (for example). Any instrument will have some error of this type, but the idea of calibration is to keep this kind of error reasonably small.A wrongly calibrated instrument is one that shows the wrong measurement.

What is the difference between calibration and measurement?
Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device. 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.

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?
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..
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).
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.
IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?
It depends on the calibration of the instrument you are measuring with.
