Method for determining the resistance value of a measurement resistor and assembly for carrying out such a method

Abstract

The invention relates to a method for determining the resistance value of a measurement resistor, comprising the following steps: a) providing an assembly for measuring the strength of an electric current, wherein the assembly comprises a measurement resistor and a reference resistor, b) defining a resistance ratio, c) measuring the resistance value of the measurement resistor by means of a first measurement device, d) measuring the resistance value of the reference resistor, e) adjusting the resistance value of the reference resistor such that the ratio of the resistance value of the reference resistor to the resistance value of the measurement resistor equals the defined resistance ratio, f) integrating the assembly in an application environment, g) measuring the resistance value of the reference resistor in the application environment by means of a second measurement device, h) determining the resistance value of the measurement resistor from the resistance value of the reference resistor measured in step g) and the resistance ratio known from step b). The invention also relates to an assembly for carrying out such a method.
