Definition and function of weights
A calibration weight is a precisely manufactured mass block used to provide a standard mass or load during the measurement process. Its main applications include:
a. Calibration of measuring equipment: such as balances, electronic scales, etc., to ensure that the readings they display are accurate.
b. Calibration of other equipment: such as certain mechanical equipment, used to determine the load or other parameters of the machine.
c. Providing standards for scientific research: In some experiments, accurate mass is required as a reference, and weights come in handy.

Production and manufacturing of calibration weights
The process of manufacturing calibration weights requires highly precise equipment and strict manufacturing standards. It mainly includes the following steps:
a. Material selection: ensure the purity and stability of the material.
b. Molding process: Use specific molds and processes to shape the material into the required shape.
c. Fine processing: Including grinding, polishing, etc., to ensure that the surface of the weight is smooth and achieves the required accuracy.
d. Quality inspection: Use high-precision measuring equipment, such as electronic balances, to perform quality inspection on the weights.
Maintenance and care of calibration weights
In order to ensure the long-term stability and accuracy of the weights, regular maintenance and care are required:
a. Storage conditions: Store in a moisture-proof and dust-proof place, avoid direct sunlight and high temperature.
b. Cleaning and maintenance: Use special detergents and soft cloth for regular cleaning.
c. Regular calibration: Use standard weights or other equipment to calibrate it every once in a while.
