Overview of Instrument Calibration

  1. 1. Overview of Instrument Calibration Presents by NCQC, India
  2. 2. What is Calibration? Calibration is the activity of checking, by comparison with a standard, the accuracy of a measuring instrument of any type. It may also include adjustment of the instrument to bring it into alignment with the standard. www.calibrationlaboratory.in
  3. 3. Why is Calibration Necessary? It is impossible to make perfect hardware that would not need any form of error correction. Even making the hardware good enough to eliminate the need for error correction for most devices would be extremely expensive. The accuracy of network analysis is greatly influenced by factors external to the network analyzer. Components of the measurement setup, such as interconnecting cables and adapters, introduce variations in magnitude and phase that can mask the actual response of the device under test. The best balance is to make the hardware as good as practically possible, balancing performance and cost. Calibration is then a very useful tool to improve measurement accuracy. www.calibrationlaboratory.in
  4. 4. Purpose of Calibration Calibration refers to the act of evaluating and adjusting the precision and accuracy of measurement equipment. Instrument calibration is intended to eliminate or reduce bias in an instrument's readings over a range for all continuous values.  Precision is the degree to which repeated measurements under unchanged conditions show the same result  Accuracy is the degree of closeness of measurements of a quantity to its actual true value. www.calibrationlaboratory.in
  5. 5. When do Instruments Need to be Calibration?  Before major critical measurements  After major critical measurements  After an event  When observations appear questionable  Per requirements  Indicated by manufacturer www.calibrationlaboratory.in
  6. 6. What is Important of Calibration? Calibration of a measuring equipment or working standard enables the user to take note of the deviations and errors from the nominal values so that corrections can be made to minimize the errors during measurement. A well-calibrated instrument provides the confidence to the user as well as the consumer that the service or the product meets the required specifications and ensures the acceptance in international market. www.calibrationlaboratory.in
  7. 7. Requirements of Calibration Management System Each instrument requires:  Unique identification  A recorded history and current calibration status  Use appropriate for the function of the instrument Calibration procedures require  Approved procedures for calibration  Schedule for calibration  Process range limits Calibration standards and test equipment  Must be more accurate than the required accuracy of the instrument  Traceable back to national or international standards Personnel  Proof of appropriate training  Perform within an established change management process www.calibrationlaboratory.in
  8. 8. Futures of Calibration System at NCQC  Identifies instruments that can be calibrated  Determines calibration requirements for instruments  Establishes calibration procedures  Develops corrective action procedures  Documents calibration results and activities  Supports audit trails for calibration system www.calibrationlaboratory.in
  9. 9. About NCQC - Calibration Laboratory in India National Centre for Quality Calibration Laboratory The NCQC was founded in 1998 for instrument calibration laboratory. Since then, we have steadily grown by adding many new facilities, capabilities including primary and secondary instrumentation to become leading NABL calibration laboratory in India. We provide calibration services to our customers in either our own environmentally controlled multi-laboratory facility or on-site at their location. We are NABL accredited Calibration Lab is having wide scope of thermal, mechanical and electro-technical instrument calibration. We had our branches in Gandhidham, Ankleshwar, Bhavnagar, Rajkot and Vapi. www.calibrationlaboratory.in
