Disclosed is a method for commissioning a magneto-inductive flow measuring device having means for producing a magnetic field and at least one measuring electrode pair for sensing a potential difference in a medium. The method includes a settling of the means during a settling time for stabilizing the magnetic field. During the settling time a first voltage time function is applied to the means, wherein after the settling time a measuring time begins, wherein during the measuring time a second voltage time function is applied to the means, wherein the settling time is divided into first time intervals, each of which has a duration, wherein the measuring time is divided into second time intervals, each of which has a duration, wherein an average value of all first interval durations is always less than an average value of all second interval durations.
