Abstract

A high precision weighing system and weighing method has a weighing plate and weighing unit separation mechanism and a weight loading mechanism. The weighing plate and weighing unit separation mechanism controls separation of a weighing plate and a weighing unit, so that the weighing plate or the weighing plate and its carried material do not apply force to the weighing unit. The weight loading mechanism loads a weight onto the weighing unit or removes a weight from the weighing unit; the weighing system records a weighing value of the weighing unit during the action of the weighing plate and weighing unit separation mechanism and a sensitivity value during the action of the weight loading mechanism. The weighing system modifies the weighing value at the time of the most recent combination of the weighing plate and the weighing unit based on the recorded weighing and sensitivity values, achieving a high precision.
