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 F1 Calibration Weights - Appropriate for calibrating high-precision top loading balances with a readability as low as 0.01 g to 0.001 g. OIML Class F1 weights can be used to calibrate precision balances, Class I and Class II laboratory balances, and digital scales. OIML Class F1 weights are equivalent to ASTM Class 2 and 3 weights
