International Society of Automation 67 T.W. The standard input is varied within the range of measurement of the instrument to be calibrated. This seems obvious, but The calibration of EDM instruments is carried out to determine the instrument corrections to be applied to measurements and to ensure its reliability. This means that you can verify a measuring instrument without calibrating it. To check the operation of an instrument which has had a shock, vibration, or exposure to To improve the accuracy of a measuring instrument. 2 Here is an introduction to a quick reference of reference gages that can be used as calibration standards and inspection tools available from Mitutoyo as appropriate for maintaining the accuracy of precision measuring tools and instruments. calibration. Find the current range of the instrument when used as an ammeter with the coil connected across a To test an instrument after it has been repaired or modified. Acko: Calibration of Measuring Instruments on a Coordinate Measuring Machine 131 calibration of reference gauge blocks by interferometry U = 0,02 µm + 0,2⋅10-6⋅L substitution measurement on CMM U = 1,8 µm + 4⋅10-6⋅L calibration of gauge rings U = 0,4 µm + 3,1⋅10-6⋅L calibration … Pressure and temperature a) The coil of a measuring instrument has a resistance of 1 Ω and the instrument has a full scale deflection of 250 V when a resistance of 4999 Ω is connected with it. Based on the standard input and the values obtained from the instrument, one can calibrate the instrument. We know that there are uncertainties in the reading obtained from the instrument… 8. 6.8.2 Dial indicators are not used as measuring devices, only as comparators, and do not come within the Thomas Keating requirement for calibration 6.9 All new measuring equipment purchased or manufactured in house shall be passed to the Quality Manager for calibration, identification and production of a record card. (1) where : Res is the resolution of the measuring instrument, adopted during calibration To have confidence in a measuring instrument’s results. It must be noted that in the definition of ISO guide 25 the word “calibration” is not used. Calibration Software, Reduction and Interpretation The BaselineWA EDM calibration software has been developed by Landgate for the calibration of EDM instruments against standard baselines. This is a point where one could discuss two types of calibration for NIR instruments. FIELD INSPECTION AND CALIBRATION OF MEASUREMENT INSTRUMENTS George E. Brown III Reliant Energy – Entex 210 W. Larissa, Jacksonville, Texas 75766 BASIC TEST PROCEDURE Basic instrument proving procedure is simulating all conditions the device was designed for, and testing for accuracy at several points. To test a new instrument. Alexander Drive PO Box 12277 Research Triangle Park, NC 27709 E-Mail: info@isa.org Phone: (919) 549-8411 Fax: (919) 549-8288 measuring instrument satisfies its specifications, if it does not it should be either repaired or corrected, or downgraded, or even decommissioned. for the minimum measurement uncertainty expected for a measuring instrument. To check the accuracy of a measuring instrument. The first calibration is used to align the spectrometer performance for precise and accurate response for wavelength registration, photometric (absorbance) registration, line shape and resolution, linearity in detector response, and stray light characteristics. Why do we calibrate?
