The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

UNTIL recently the measurement of currents at radio-frequencies has depended on the assumption that the instruments used did not alter their calibration with frequency, and every endeavour was made to ...

A measurement or observed value is discussed as the sum of two components-one the absolute value of the characteristic measured and the other an error of measurement ...

Test instruments such as oscilloscopes and DMMs (digital multimeters) often let you get the measurement results you need with just the press of a button. But the number on a meter's display or the ...

ISA recently published the third edition of Calibration Handbook of Measuring Instruments by Alessandro Brunelli. In this Q&A feature, Brunelli highlights the focus, importance, and differentiating ...

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...
