Abstract
The method comprises producing a measurement signal (s1) having a signal parameter, followed with a temporal change (Δx1/Δt; Δx1′/Δt) of a primary measured variable (x1) and a temporal change (Δy1/Δt) of a disturbing variable (Δ1), and producing a measurement signal (s2) having a signal parameter, followed by a temporal change (Δx2/Δt; Δx2′/Δt) of a primary measured variable (x2). The method comprises ascertaining measured values (XI) of first type representing the primary measured variable (x1) or a secondary measured variable (f(x1) Δx1′) of measured values (XII) of second type representing the primary measured variable (x2) or a secondary measured variable (f(x2) Δx2′). The method comprises using measured values (XI) of first type and measured values (XII) of second type for ascertaining an error characterizing number (Err) representing a velocity error (ΔXI/ΔXII) caused by a change of the disturbing variable (y1).
