Calibration
Calibration ensures that the weighing scale provides accurate readings according to a set standard. During calibration, a technician adjusts the scale to eliminate any errors by comparing its readings with certified reference weights.
Calibration is typically performed as part of regular maintenance or after any repairs. It helps keep the scale’s accuracy within acceptable limits, ensuring that the readings are reliable.
Calibration certificates are often provided as proof that the scale has been checked and adjusted to meet the required tolerances.
Stamping
Stamping, or verification, is a legal requirement performed by government-authorized bodies (like the Weights and Measures Department) to confirm the accuracy and compliance of the scale with local standards.
During stamping, the authorized official checks the scale’s calibration and overall condition. Once approved, they affix a stamp or seal on the scale, indicating it has passed the verification process and meets regulatory standards.
Summary
In summary, Calibration is the process of checking whether the machine is showing the correct weight or not whereas stamping is a legal procedure for all the weighing scales. It is mandatory to have the stamping done every year, if found guilty it may result in fines or severe punishments.
Calibration is an internal process to maintain the scale’s accuracy, while stamping is an external regulatory check required to legally validate the scale for trade use.
