Calibration Weights and Calibration Mass Sets
Calibration Weights are used to check the reading of scale, to make sure it is still accurate. They used when calibrating a scale. While the calibration states how a scale behaves, adjustment of the scale changes its behavior. What it dose is a set of operations carried out on a scale so that it provides prescribed indications corresponding to given values of a quantity to be measured. Therefore, adjusting a scale means modifying its indications in a way that allows them to correspond – as much as possible – to the quantity values of the measurement standards applied.

ANSI/ASTM Class F (Class 5) Scale Weights - For student laboratory use or low precision scales ASTM Class 5 scale weights and weight sets should be used in classroom settings or where simple weight calibrations are needed. A Class 5 scale calibration weight can be used to calibrate Class III digital scales and other weighing scales. Class 5 weights are equivalent to OIML Class F1 weights. Includes Grip Handle Weights, Hanger Weights, and Slotted Weight styles.
