PROBLEM TO BE SOLVED: To perform easily and precisely a calibration treatment such as two point correction in an electronic azimuth meter. SOLUTION: The electronic azimuth meter includes a first memory control means which stores a first and a second data output from a geomagnetism detection means when a first switch is input (step S24), an azimuth memory control means which calculates and stores an azimuth indicated by an azimuth display means at inputting the first switch (step S25), and a specific azimuth indication control means which controls an azimuth display means to indicate the stored azimuth even when an instrument body is rotated during waiting a second switch input after the first switch input (S27, S28). A correction data is obtained from the data taken during the first and the second switch inputs (S31). COPYRIGHT: (C)2010,JPO&INPIT
