Abstract

In this paper a solution for metrological calibration of <i>digital instruments without built-in communication interface</i> (DIWIs) is presented. The solution is based on the conversion in numerical data of video camera images of DIWI display. The paper describes the vision algorithm used, illustrates the functionality of the realized software (in LabVIEW environment), and presents the results of an actual calibration experiment performed on a Fluke model 189 True RMS digital multimeter.
