A memory stores compensation factors with sets of components of the gravitational acceleration, each of the first compensation factors being a ratio between the true weight value of a material and an apparent weight value of the material, which is assumed to be measured by the weight measurer when the planar surface is inclined at an angle. The weighing scale further includes a compensator that refers to the memory for obtaining an appropriate compensation factor corresponding to the components of the gravitational acceleration currently being measured by the acceleration sensor. The compensator compensates for, by the obtained compensation factor, the apparent weight value of the object to be weighed indicated by the weight data currently being output from the weight measurer. | 10-30-2008 |
