Abstract: An electronic balance includes a weighing pan, a windshield, door opening and closing mechanisms configured to automatically open and close doors of the windshield, a weight sensor, a built-in weight, a weight applying and removing mechanism for the built-in weight, and a control unit, the control unit obtains a first standard deviation measured while the doors of the windshield are left closed, and a second standard deviation measured accompanied by a series of opening and closing operations consisting of opening the door by the door opening and closing mechanism, loading the built-in weight by the weight applying and removing mechanism, closing the door by the door opening and closing mechanism, acquiring weighing data of the built-in weight, opening the door by the door opening and closing mechanism, unloading the built-in weight by the weight applying and removing mechanism, and closing the door by the opening and closing mechanism.

Abstract: Provided is a weighing apparatus and a method capable of quantifying a failure risk based on an impact load and proposing an inspection content according to an impact. In order to achieve the object described above, a weighing apparatus includes a weighing sensor, an impact load quantifying unit configured to quantify an impact load from an acceleration of a load transmitting unit configured to transmit a load of a weighing object to the weighing sensor, and a failure risk level calculating unit configured to calculate an impact level based on a numerical value of the impact load, and calculate a failure risk level from the number of detections of the impact level in a predetermined period of time from past to present and a weighting coefficient according to the impact level.
