With the rapid development of digital insturuments, there are increasing needs in medium and small sized enterprises to replace analog meters with digital ones. For utilization of such digital meters we have to set up specialized software. However, shortage of available software prevents us from manipulating effectively various functions equipped with the meters. It has been known that the graphical programming(Virtual Instrumentation) method is capable of visualizing measurement and control processes in the windows environment. In this paper, based on Virtual Instrumentation we report experimental results on effective visualized and automatic measurements. The results are obtained for calibration of multimeters and powermeters of typical digital instruments. To this end, we designed a virtual instrument for measurements, and we made a table available for processing data by utilizing the recent ActiveX.
