FIELD: technological processes.
SUBSTANCE: sensitive element is heated for a certain difference of temperatures compared to nominal working temperature, for instance, by means of rise of voltage that is supplied to the element. Gas analyser readings change due to element heating is fixed, and the value of change is used to determine actual concentration, using previously established functional dependence between change of readings due to element heating by specified difference of temperatures and concentration of measured component. Then nominal temperature is restored, and after gas analyser readings are stabilised, its value is preset for the value that corresponds to found concentration.
EFFECT: simplification of adjustment and reduction of its duration under operation conditions.
