Calibration Weight

In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Calibration weights (also known as reference weights or test weights) are manufactured for calibrating weighing equipment. Some calibration weights may also be used as reference weights for the calibration of improvised or non-certified weights. Calibration weights may be taken the form of simple discs, cylinders, wires, or leaves, and constructed of aluminum, stainless steel, brass, iron, and other alloys.
