PROBLEM TO BE SOLVED: To provide a weighting device for enabling a user to accurately have a clear view of a period when a load sensor reaches a use limit.SOLUTION: The weighting device includes: a load sensor 2 for supporting holding means 1 which holds an object to be weighted; an A/D converter 4 for A/D converting the output signal of the load sensor 2; a control device 5; and a display part 7. The control device 5 performs processing of converting the output value of the A/D converter 4 into a measured value corresponding to the weight of the object to be weighted, and when the measured value obtained by converting the output value of the A/D converter 4 when the object to be weighted is not held by the holding means 1 is not zero, performs zero adjustment processing to set the measured value to zero, and when the zero adjustment processing is performed, calculates at least one of a lower limit margin value as a difference between the lower limit values of two ranges, that is, the output range of a digital value at a current point of time of the A/D converter 4 corresponding to a measurable weight range and the range of a specified digital value which can be output and an upper limit margin value as a difference between the upper limit values of those two ranges, and allows a display part 7 to display information related to the calculated margin value. |
