Claims

[Scope of utility model registration request]

In an electronic scale that includes a weight detection device that outputs digital weight data based on an output signal of a weight detection element corresponding to a load, and a display that digitally displays this weight data, a timing device that measures a predetermined time; Read the drift range regulation data setter that sets the drift range regulation data that is allowable as a drift, and each weight data before and after the elapse of a predetermined time measured by the timing device, find the difference between both data, and use the difference to define the drift range. a comparator that compares the data; a drift storage device that stores the difference between the weight data within the drift range defined data range obtained by the comparison with the comparator as drift data;
An electronic scale comprising: an arithmetic unit that performs a correction calculation to correct weight data by adding and subtracting weight data after a predetermined period of time and drift data stored in a drift storage device.
