Abstract

A calibration assisting device includes a reference load data storage means 30d for storing, as a reference load data, the reference load data produced from load sensor 10 when a desired reduced quantity is generated in a vehicle weight measuring device 40, a load data fetching means 30a1 for fetching the load data produced from the load sensor 10, a tire load data fetching means 30a2 for fetching a tire load data produced from the vehicle weight measuring device 40, a reduced quantity detecting means 30a3 for detecting a reduced quantity on the basis of the tire load data thus fetched, a calibration information creating means 30a4 for creating calibration information on the basis of the load data fetched by the load data fetching means 30a1 corresponding to the tire load data and the reference load data stored in the reference load data storage means 30d when the reduced quantity is detected, and a calibration information outputting means 30a5 for outputting the calibration information produced from the calibration information creating means 30a4. In such a configuration, the calibration assisting device can assist the calibration of the weight meter.
