<p>PROBLEM TO BE SOLVED: To write a polynomial approximate expression without using an exclusive writing device. SOLUTION: This digital memory-type hot-wire anemometer comprising a wind seed detecting part 10 for outputting a wind speed value detected by a hot-wire 20 as a sensor, as a voltage value, a polynomial approximate expression storing part 12 for storing a polynomial approximate expression for calculating the wind speed value from the voltage value, and a wind speed value calculating means 36 for calculating the detected with speed value by applying the voltage value outputted by the wind speed detecting part 10 to the polynomial approximate expression stored in the polynomial approximate expression storing part 12, further comprises a standard voltage value storing part 30 for storing at least two or more standard voltage values on the basis of the reference wind speed outputted by the wind speed detecting part 10, corresponding to the reference wind speed, a polynomial approximate expression preparing means 38 for preparing the polynomial approximate expression on the basis of at least two or more standard voltage values, and a polynomial approximate expression storing means 40 for writing and storing the prepared polynomial approximate expression in the polynomial expression storing part 12.</p> |
