<p><P>PROBLEM TO BE SOLVED: To record the state of a measuring object with respect to passage of time, without causing shifts in time. <P>SOLUTION: An RTC (real-time clock) 2 with a radio controlled timepiece is provided with the real-time clock for performing time clocking and the radio-controlled timepiece for reading standard time, based on the time information broadcast on the standard electric wave. The RTC 2 with the controlled timepiece corrects the time of the time clock, based on the standard time shown by the controlled timepiece. Upon receiving measurement value obtained through measurement using a temperature sensor 4, a CPU 1 obtains the time then from the RTC 2 with the controlled timepiece, and records the temperature measured by the temperature sensor 4 to a memory 9, together with measured time shown by the RTC 2 with the controlled timepiece. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
