To those who wish to double production efficiency Just 5 mg after 30 million times! EM-DLC* AD-4212C-300 (320 g × 1 mg) completed an endurance test of 30 million repeated loadings, which took more than 1 year. The final value of span drift was a mere 5 digits, or 5 mg (display value of 200.005 g for a standard weight of 200 g), demonstrating that the product can maintain its accuracy over a long period of use.
