Abstract:
A method of constructing an output characteristic correction database indicating output characteristics of a plurality of load measurement sensing devices disposed in a transport device at portions supporting a carrier of said transport device, comprising the steps of:correcting the outputs of said sensing devices in accordance with transport device characteristics determined on the basis of variations in output characteristics of said sensing devices and a structure of said transport device, by use of weight vessels disposed on said carrier;changing an amount of a liquid contained in the weight vessel to thereby change the weight of said weight vessel containing said liquid while making the value of the weight of said weight vessel containing said liquid known to said database; andcollecting and storing at least one of the amount of the liquid and the weight of said weight vessel while relating it to the outputs of said sensing devices whenever the amount of the liquid in the weight vessel is changed.
