Abstract
A measuring method for measuring physical variables comprises—the selection of a working point (AP) lying within a total measurement range (G) of a physical variable (M) to be measured,—the detection of a measured value (M(t1)) of the physical variable at a first measuring time (t1),—the determination of a displacement value (V(t1)) as the result of a subtraction of the measured value (M(t1)) measured at the first measuring time from the working point (AP),—the formation of change values (C(t2), C(t3) . . . C(tx)) of the physical variable (M) by acquiring subsequent measured values (M(t2), M(t3) . . . M(tx)) of the physical variable at subsequent measuring times (t2, t3 . . . tx) and addition of the displacement value (V(t1)) to the subsequent measured values.
