A measurement equipment scale is a device used to determine the weight or mass of an object. Scales can vary in their design and functionality depending on their purpose. Here's a basic overview of different types of measurement scales and their key components:

Calibration is the process of adjusting the scale so that its measurements align with a standard or known weight. Over time, scales can lose accuracy due to wear and tear, and regular calibration ensures the readings remain precise.

Calibration certificates are usually provided to confirm compliance with industry standards (e.g., ISO, NIST).
