First Claim
1. A measuring method for measuring physical variables, comprising:
- the selection of a working point within a total measurement range of a physical variable to be measured,the detection of a measured value of the physical variable at a first measuring time,the determination of a displacement value as the result of a subtraction of the measured value from the working point,the formation of change values of the physical variable by acquiring at least one subsequent measured value of the physical variable during at least one subsequent measuring time and addition of the displacement value to the at least one subsequent measured value.

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 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 measures 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.

5. A measuring system having a sensor for detecting a physical variable and for emitting measured values of the detected physical variable, having an analog-digital converter for detecting the measured values emitted by the sensor and for converting them into digital measured values, wherein said system further comprises:
- a calculator for determining a displacement value as the difference of a measured value measured at a first measuring time from a selected working point lying within a total measurement range of the physical variable, and a processor for adding the displacement value to the measured values supplied to the analog-digital converter, so that as output values the analog-digital converter supplies change values of the physical variable.
