According to the different accuracies and purposes of weights, the weights used for calibration or verification of weighing instruments with high accuracy, as well as the weights used for value transfer in the laboratory, are usually referred to as working weights, standard weights, and reference weights; The weights directly used on site to determine the mass of the object being weighed are called working weights. OIML divides weights into seven levels: E1, E2, F1, F2, M1, M2, and M3, and provides detailed regulations on their uses, tolerances, structural shapes, materials, and processing requirements.


Weighing instruments are an important component. Due to people's lack of understanding of the importance of adding weights, they do not pay attention to their storage, and even use them as hammers to smash things, nail nails, or place them on the stove to cushion lunch boxes. This can cause inaccurate quality of adding weights. Therefore, it is necessary to strengthen the understanding of the importance of adding weights and ensure correct use and storage.

◇ It is strictly prohibited to come into contact with corrosive substances

The additional weight must be verified and qualified before it can be used

Before use, use a soft bristled brush or specialized wiping cloth to remove dust from the surface of the weight

The principle of "minimum number of weights" should be followed in weighing.

◇ Strictly prevent collisions or falls, avoid injuries or scratches

The weight should be placed gently in the center of the scale pan, with the large weight in the center and the small weight around the large weight. Do not place it sideways or stack it together.
