JJF 1940-2021 《Calibration Specification for Electromagnetic Balances》 Related products

JJF 1940-2021 Electromagnetic Balance calibrating specification applies to the calibrating work of electromagnetic Balance. Electromagnetic Balance uses the combination of the principle of lever equilibrating and the principle of electromagnetic force equilibrating to measure the mass of an object. This specification refers to a number of related documents, including mechanical balance, weight, electronic balance and other calibrating specifications and general measurement terms and definitions. The terminology includes definitions of electromagnetic Balance, such as the distinction between two-disc electromagnetic balance and single-disc electromagnetic balance, as well as the definition of electrical Measurement range and actual interval scale. Measurement units of electromagnetic Balance calibrating include kilograms, milligrams, grams and tons. This specification ensures the precise weighing capacity of the Electromagnetic Balance under different loads to meet the requirements of mass measurement.
