Abstract

In a method and arrangement for determining a requirement to replace a component in a device, the measurement of a first parameter that has an unbeneficial influence on the consumption or the service life of the component is replaced by the measurement of at least two parameters that represent the first parameter and whose changes allow the current condition of the component to be calculated. A count reading is thereby modified such that it approaches an outage threshold that is specific for the component and such that the device emits a warning before the end of use or end of the service life of the component part is reached. The invention can be advantageously utilized for the indirect measurement of parameters of components that are located in a security module or in its immediate proximity, for example for determining a requirement for battery replacement for security modules.
