A system for analysing a fluid sample arranged on a test element comprises a data processing unit configured to process results of an analysis of the fluid sample arranged on the test element, an audible signal generator, and a control unit. The control unit may control the audible signal generator to generate an audible test signal that is configured to test the operability of the signal generator to audibly encode information. The audible test signal may include audible features that allow for identification of any deviation of the generated audible test signal from a correctly generated audible test signal, and/or from which malfunction of the signal generator can be detected.
