分銅内蔵型電子天びん。 The output of the load detection unit with the plate engaged above is converted into mass using the span coefficient in the memory, and it also has a built-in calibration weight and its addition/subtraction mechanism, and drives the addition/subtraction mechanism to convert the calibration weight. In a balance equipped with a calibration program that adds or subtracts the above to the load detection section, updates the span coefficient from the output of the load detection section when the calibration weight is loaded and when it is not loaded, and updates the contents of the memory. sensor and
It has a determination means for determining whether the output of the temperature sensor has changed by more than a predetermined value since the previous calibration, and based on the determination result, when a preset temperature change occurs, the above calibration program is automatically executed. The calibration weight is formed in a gap between the bottom surface of the pan and the top surface of the balance housing, or by protruding the top surface of the balance housing toward the bottom surface of the pan. An electronic balance with a built-in calibration weight, characterized in that the electronic balance is disposed in a space above the interior of the housing.
