An indicating device (2) intended to indicate the function of a pressure sensor (4) arranged so as to measure the pressure in a medium. The indicating device (2) is adapted so as to receive a pressure signal (10) from the pressure sensor (4) and a time signal (12) indicating the time point ts of a pressure change in the medium (6), the indicating device (2) being further adapted so as to determine said pressure signal (10) after the pressure change during a predetermined measurement period, and to determine at least one parameter Y for the pressure signal (10), wherein the indicating device (2) is arranged so as to compare said determined parameter Y to one or a plurality of threshold values UpsilonT, and to generate an indication signal (14) in dependence upon said comparison, and wherein the indication signal (14) is adapted so as to indicate the function of the pressure sensor (4). |
