<P>PROBLEM TO BE SOLVED: To provide an altimeter capable of performing accurate altitude measurement by appropriately setting a reference altitude without obliging a user to take a lot of effort in such a contest that the user has to run on a mountain continuously for a long stretch of time. <P>SOLUTION: The altimeter includes: altitude calculation means for calculating an altitude based on atmospheric pressure and set data of a reference altitude; time measurement means (S14) for counting time from start; and halfway time calculation means (S21) for calculating lap time or split time when a switch part is operated during the time measurement. The altimeter includes also altitude storage means for storing altitudes of a plurality of lap points or a plurality of split points and reference altitude changing means (S25) which in each operation of the switch part, updates the set data of the reference altitude by altitude data corresponding to the lap point or the split point stored in the altitude storage means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
