1. A method for monitoring an arrangement for determining concentration of an analyte in a body fluid, the arrangement having an interface through which the body fluid passes, a flowmeter chamber which receives a stream of the liquid and carries out a measurement to determine concentration of the analyte, and a signal processor which evaluates the measurement, the method comprising the following steps:

  • using a sensor system to obtain measured values of at least two correlated system parameters of the arrangement;

    comparing the measured values with limit values stored for each of the system parameters in a storage unit to obtain at least two comparison results; and

    determining with the signal processor whether a malfunction has occurred in the arrangement based upon the at least two comparison results.
