• The studies to measure the unsteady flow by means of a combined probe were shown in the previous papers. However there have been left two problems unsolved: One of them is the convenient procedure to process great many time-series data, and the other is the way to confirm the accuracy of the measuring systems. These means were established by using a digital data processor, improving the experimental devices and developing the computer program. In this paper, the calibration procedure of a combined probe is presented and the error estimation in flow measurements is discussed with the application of characteristic polynomials which are derived from the regression analysis for the calibration data using digital computer. To formulate the probe characteristics as polynomials is greatly useful in measuring unsteady or steady multi-dimensional fluid flows.
