Scale Calibration

What is scale calibration?
Calibration of a scale is a procedure in which a Licensed Scale Technician uses known weight certified by the State of North Carolina Bureau of Weights and Measures, to adjust the response of a mechanical or electronic weighing system to the following tests; The indicator must show zero when there is no weight on scale. When a known weight is applied the indicator must display the exact amount of applied weight within a specified tolerance. When weight is applied or removed incrementally the scale must display weight equal to that on the scale within a specified tolerance.

Why is calibration needed?
All scales need to be calibrated when first placed into service to insure accurate operation. Any scale will, in time, drift away from its original calibration for various reasons. Wear of mechanical components, age and degree of use all contribute to calibration drift. Most state's law require that any scale used to sell a commodity or service must be inspected and certified as to it’s accuracy.
