MEASUREMENT DIAGNOSTICS BY ANALYSIS OF LAST DIGITS

摘要

Though measurement instruments and methods have their natural precision limits, long term monitoring, which is so important for environmental studies, requires to set up and maintain certain standards regarding precision. The elementary further develops and allows to increase the number of valid digits, the change should be documented. In this paper we discuss a simple pro- cedure for validity assessment of the last digits of data in a data base. It may be useful for both calibration control of an instrument as well as for preliminary data analysis in scientific studies.
