Abstract A computer-aided calibration method for hot film probes is presented which tolerates statistical and some systematic errors, and which allows data evaluation in real-time. Essentially, the velocity is approximated by a power series at each yaw angle and for each sensor. A weighting function minimizes the influences of errors. At measurement time the anemometer voltages are roughly linearized. The digitized voltages are subjected to a combination of iteration and interpolation in order to compute the velocity components. RMS-values of the two velocity components parallel to the wall, u and w, and of their partial derivatives with respect to time in a turbulent wall boundary layer are shown and will be used for comparison.
