<p><P>PROBLEM TO BE SOLVED: To perform time correction without causing duplication or deletion of measurement data. <P>SOLUTION: A first time length (delay of 6 minutes), showing delay or lead of an internal clock to the present time (7:00), based on the present time information from an external device, is specified. When the internal clock delays by the first time length, the processing of leading the internal clock by a third time length (3 minutes) shorter than a second time length (4 minutes), between the start time (6:56) of time correcting processing and start time (7:00) of measuring processing to be performed, after time correcting processing is executed as the time correcting processing by a predetermined number of times (2 times), until the first time length becomes a previously specified time length or shorter. When the internal clock leads by the first time length, the processing of delaying the internal clock by a fifth time length which is shorter than a fourth time length between the start time of the previously executed measuring processing; and the start time of the time correcting processing is executed as the time correcting processing by the predetermined number of times until the first time length becomes a previously specified time length or shorter. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
