Open software, suitable for all volumetric instruments, irrespective of the manufac-turer. 1821 0 obj <> endobj The set of criteria defined for the instruments, which are used to measure the quantities which are slowly varying with time or mostly constant, i.e., do not vary with time, is called ‘static characteristics’. Instruments … Mechanical type flow meters. Sélection de programme (programme . The selection of measuring instruments is a complex task, which depend on the size, the character and the value of measured magnitude. The measuring instruments are the most important part of the measuring process so their selection have to be done carefully. 203 27 END KEYPOINT In this unit inspection technologies, particularly automated inspection technologies, are investigated. ��;3މ2�#C��`~ The in-situ instruments:. The purpose of this paper is to analyze the existing methods for selection of measuring equipment. Selecting the right instrument for a given measuring application can be a challenge. ! 0000002863 00000 n More specifically, it is the IEC 61010-031 standard and its amendment A1 which define the safety rules for measuring instruments and their associated accessories. 0000004824 00000 n trailer In its latest edition applicable from 1st March 2011, this standard has been completed ���\����\�����G��CS���o4����`���t�:��C��e��-��@S]����":�S�*3R-����00p�r�8�L0�j8���h�(��GK�b��k��aA��\�t��6�&r��)er���*O��\R�,&�������P���ubE'�Ȩ.ŀ ]�*̂���̂��b�.Zb�.�IJ ;��X Rain gauges are discussed in this chapter.
