Definition and function of weightsA 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.
