Calibration Of Measuring Instruments

Calibration of the measuring instrument is the process in which the readings obtained from the instrument are compared with the sub standards in the laboratory at several points along the scale of the instrument.

Calibration of measuring instruments.

The accuracy of the standard is required to be ten times the accuracy of the measuring instrument. As per the results obtained from the readings obtained of the instrument and the sub standards the curve is plotted. During monitoring activities we use calibrated measuring instruments to achieve confidence with our monitoring results. Hb 145 was developed as a source of calibration procedures for weights and measures laboratories and covered mass length and volume calibrations for field.

The following steps will help you establish an instrument calibration procedure or tune up your existing one. Fundamentally measurement is a process which checks whether something is. Oppermann is out of print and the majority of content has been updated and published in the publications noted below. Management should be confident that their measuring devices are reading correctly.

If the instrument is accurate there will be matching of the. Nbs handbook 145 1986 handbook for the quality assurance of metrological measurements by john k. In order to achieve the finest measurement and thereby the correct decision based upon it calibration of equipment both before and after use is essential. Does nist require or recommend specific recalibration intervals for measuring instruments devices or calibration standards.

Early detection of defects damage apart from drift instruments are also prone to damage and defects due to loose connections or faulty components. Identify the measuring devices instruments develop a comprehensive list of every device in your facility that is used to measure something. Taylor and henry v. To the instrument engineer or technician calibration is the process of determining the relationship between the values of the quantity being measured and that indicated on a measuring instrument.

In general nist does not require or recommend any set recalibration interval for measuring instruments devices or standards. This both establishes metrological traceability for the measurement and fulfills the requirements of iso 9000. Calibration helps identify the amount of drift which helps analyze instrument stability and measurement consistency. Specific recalibration intervals depend on a number of factors including.

It is the process of checking the reading of the device to see how the measurement compares to the true value. Because we are performing a measurement we are using measuring devices equipment and instrument or in general measuring resources that must undergo calibration to deliver a reliable result.
