Abstract

Vernier calliper is very much used either by measurement laboratories and production. Vernier calliper measurement tools necessary to calibrate each period of 12 months, with a calibration done will determine the value of the correction/error and the value of the measurement uncertainty of measuring instruments vernier calliper. In this study calibration of vernier calliper follow the standard JIS B 7507 - 1993 at which the standard has been described specification requirements vernier calliper. Based on the results of the calibration has been done vernier calliper I have a maximum error of 0.00042 mm and the value of the uncertainty confidence level at 95% with a coverage factor of k = 2 is U95 = ±59.02 μm, vernier callipers II has a maximum error of 0.01994 mm and uncertainties confidence level at 95% with a coverage factor of k = 2 is U95 = ±59.42 μm. Both vernier callipers meets the requirements based on JIS B 7507-1993.Keywords: Metrology, Calibration, Vernier Calliper
