Specification:Name: fashion precision mechanical scalesSize: 36.5*36*6.5cmWeighing range: 0-180KGType: MechanicalAbout the error description:When the correct use according to the operating instructions, the data that differs between the weight measured by the scale and the real weight belongs to the above range, and is not a quality problem.Note:------ The mechanical scale is called the spring scale.------ There is a thick spring control gear inside to drive the mechanical arm to pull the gear at the other end, and the pointer is pointed to measure the weight. It is the reason of the new machine.------ There needs to be a running-in and stretching between the gear and the spring. Process, so every time the pointer is not at 0, you need to adjust it manually, but you don't have to adjust it for a while.
