<P>PROBLEM TO BE SOLVED: To precisely correct variations of a load signal by a difference in atmospheric pressure by detecting the difference in atmospheric pressure between the inside and outside of a storage case by a pressure difference detection means and correcting the load signal based on the difference in atmospheric pressure. Ž<P>SOLUTION: The meter for storing a load sensor 3 in the storage case 2 includes a differential pressure sensor 10 for detecting the difference between the pressure of gas in the storage case 2 and that of the atmosphere outside the storage case 2 to correct variations of a load signal, thus correcting variations in the load signal based on the differential pressure detected by the differential pressure sensor 10.
