1. An installation environment proposal method for a weighing apparatus, comprising:
(a) a step of acquiring, as weighed data of an object to be weighed, at least a weighed value, a zero-point, and a standard deviation of a span value from a weighing sensor together with time information;
(b) a step of acquiring, as environmental data, at least an atmospheric pressure, a temperature, and a humidity from an environmental sensor together with time information;
(c) a step of checking, with respect to the weighed data and the environmental data, whether an amount of change of the data per unit time or an average value of the data is less than or not less than a threshold with reference to a threshold database and obtaining a determination of influence on the weighing apparatus; and
(d) a step of making a proposal on an installation environment based on the determination of influence with reference to an improvement proposal database.
