"The paper deals with an original control system embedded in an apparatus for measurement of thermal conductivity of electrically conductive materials. The measurement method is based on one-dimensional heat conduction in a bar-shaped specimen heated by internal heat source with ends cooled by water. The control system consists of main computer, which communicates with four external measuring units. The computer contains a multiply-function card with A/D converter. A control program is written in LabVIEW environment. The algorithm carries out controlling of the specimen temperature according to a setting point, controlling of heating active mirror to compensate specimen radiation for the purpose of achieving one-dimensional heat conduction state in the specimen as well as data acquisition. Two methods of automatic control are described in the paper." . "5"^^ . "4"^^ . . "Pyszko, Ren\u00E9" . . . .
