Weighing apparatus configured to calculate failure risk, and inspection content proposing method of the same

A weighing apparatus configured to calculate a failure risk based on an impact load, comprising:

• a member that is displaced in response to a load applied by a weighing object;
• a weighing sensor that generates an electrical signal indicative of a weighed value of the weighing object;
• a displacement detection sensor that generates an electrical signal indicative of an amount of displacement of the displaced member;
• a microcontroller having a CPU that receives the electrical signal generated by the weighing sensor and the displacement detection sensor, and that includes
• an impact load quantifying circuit configured to quantify an impact load from the electrical signal received from the displacement detection sensor;
• a failure risk level calculating circuit 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, and
• a failure risk level correcting circuit configured to adjust the magnitude of the weighting coefficient according to a change in repeatability related to the weighed value.
