In a method for determining measured values from a time-dependent graph of specified values, a measurement is carried out using a measuring device, and a point in time (TM) that is associated with this measurement is determined. Furthermore, the measured value (yE) is determined by using at least two value pairs (t1, y1; t2, y2) on the time-dependent graph, each value pair (t1, y1; t2, y2) being composed of a point in time (t1; t2) and a value (y1; y2) that is associated with this point in time (t1; t2). The measured value (yE) is determined based on a corrected point in time (TK) which is determined by correcting the point in time (TM) that is associated with the measurement by using a correction term that accounts for a dead time (TT) of the measuring device.
