In the first report the authors proposed the concept of apparent angles of a hot-wire through which incorrectness of the hotwire angles as well as bias error can be eliminated. The present report is a description of the whole calibration procedure of a hotwire probe including velocity characteristics and apparent angles. These include (1) setting of the calibration table, (2) calibration of velocity characteristics, (3) calibration of apparent angles and (4) confirmation of the results. The table setting can be performed by processing the information obtained by rotating the probe axis. Velocity characteristics are calibrated in terms of the least square concept in determining optimal coefficients in the approximation equation formulated from King's law. The whole procedure is conducted under guidance by a microcomputer, which enables accurate calibration of velocity and apparent angles for three hotwires within 20 minutes.
