Abstract

A program for measuring the differential resistance of varistor materials by scanning digital images of analog oscillograms is described. The program was created using the languages HTML, CSS, JavaScript and Canvas technology. The software environment for its execution are Internet browsers. The program can be used to measure linear resistance, which limits the nonlinearity of current-voltage characteristics of varistor materials at high electric currents.
