The novelty of this work is the analysis of accuracy measures and its visualization especially for the simultaneous two parameter measurements. The parameters of the resistance-to-voltage converters, i.e. different types of DC circuits with arbitrary variable resistive sensors (of relative resistance increments), and their accuracy measures are discussed. Transfer coefficients, limited error (and also standard uncertainty) as functions of relative increments of resistance are shown in broad range for different types of supply and sensor configuration of the circuit of initial 2D converters.
