What is the allowable error for electronic truck scales?

[VanKate]

Electronic truck scales have measurement errors that are separately inspected at multiple weighing points. For example, a truck scale with a maximum capacity of 100t, a verification scale interval number of 3000, a verification scale interval of 20kg, and a minimum weighing capacity of 20kg must not exceed the allowable error values at 10 tons, 50 tons, 80 tons, and 3000 grams. The scale is considered qualified only when all these points pass inspection. Additional relevant information is as follows: Inspection Items: When inspecting truck scales at a nationally authorized metrological verification institution, there are many inspection items, such as the visual inspection of the truck scale, electromagnetic interference resistance testing, metrological mark verification, and auxiliary function checks. Metrological Standards: Truck scales belong to weighing instruments of accuracy class. Marked as Class III, also known as Class 3 scales.
