Error of indication analytical balance

WebManufacturers and scale dealers have the ability to correct errors in linearization by adjusting the balance with test weights at regular intervals of the capacity. This is not calibration, that can be performed with a single weight, provided of course that the balance has been correctly linearized. WebSemi-micro Balances . 0.01 mg : Analytical Balances . 0.1 mg : Precision Balances . 100 - 1 mg : Technical Balances . 1 g - 0.1 g : The classification is based on technical data from several manufacturers of balances. Level III and IV qualifications must be carried out, being an ISO 17025 requirement [1].
