Povzetek

Prispevek rešuje problem nazornosti pri demonstraciji merjenja električnih količin z univerzalnim električnim merilnikom s pomočjo uporabe video flex-kamere. Predstavlja vmesno fazo med razumevanjem uporabe analognih in digitalnih merilnikov ter virtualnih merilnih instrumentov.
S projiciranjem univerzalnega merilnika preko video flex-kamere in LCD-projektorja učencem omogočimo boljši pregled nad dogajanjem na učiteljevi eksperimentalni mizi in s tem krajšo pot do samostojne uporabe omenjenih merilnikov.

Abstract

The paper solves the problem of visual instruction in demonstrating the measurement of electrical quantities using a universal electricity meter with the help of a video flex-camera. It presents the intermediate phase between understanding the use of analog and digital meters and virtual instruments for measurement.
By projecting the universal meter via video flex-camera and an LCD projector, we enable students to obtain a better overview of what is happening on the teacher's desk, thus providing a short cut to the independent use of such meters.
