Electronic balance and method for stabilizing weighing accuracy by electronic balance

A method for stabilizing weighing accuracy by an electronic balance comprising a weighing pan on which a specimen is placed, a weighing mechanism joined to the weighing pan, a windshield including a weighing chamber covering the weighing pan, an opening and closing mechanism configured to automatically open and close a door constituting a portion of a wall of the weighing chamber, a moving up/down mechanism configured to automatically apply and remove the load of the built-in weight to and from the weighing mechanism, and a control unit configured to control the opening and closing mechanism and the moving up/down mechanism, and calculate a weighed value from a measurement value obtained by the weighing mechanism, comprising:

• a first step in which the opening and closing mechanism opens the door;
• a second step in which following the first step, the moving up/down mechanism applies the load of the built-in weight to the weighing mechanism;
• a third step in which following the second step, the opening and closing mechanism closes the door;
• a fourth step in which following the third step, the opening and closing mechanism opens the door after a predetermined period of time elapses;
• a fifth step in which following the fourth step, the moving up/down mechanism removes the load of the built-in weight from the weighing mechanism;
• a sixth step in which following the fifth step, the opening and closing mechanism closes the door;
• and
• a seventh step in which following the sixth step, the control unit performs zero-point adjustment of the weighed value.
