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.
OIML Class M2 Scale Weights - Scale calibration weights for general laboratory, industrial, commercial, technical and educational use. Typically fabricated from cast iron or stainless steel. OIML Class M2 scale calibration weights and scale weight sets should be used in classroom settings or where simple weight calibrations are needed. OIML Class M2 scale calibration weights can be used to calibrate Class III, IIIL, or IIII digital scales, and other weighing devices. Class M2 weights have a higher permissible error compared to Class M1. The maximum permissible error (MPE) for Class M2 weights is typically higher than that of Class M1 weights. The MPE represents the maximum allowable deviation from the true value of the weight.
